  1. Hey everyone, I'm new to programming PLCs and I've run into a problem. I have a Micrologix 1400 Series B PLC, and for the past month, I've been using a free trial of RSLogix 500 Starter. But now, the trial ran out, and so I bought a license for "RSLogix Micro Starter". The problem is that when I downloaded my updated file to the PLC for the first time with micro starter, the PLC's outputs don't work anymore. I checked the PLC screen and the inputs from the HMI screen are getting recognized, but the inputs from the physical sensors are not. Also, none of the outputs are being activated on the PLC at all, which I can tell by looking at the I/O status on the PLC screen itself. I then uploaded a new test program, where you press a button and a light turns on, but that doesn't work either. I haven't changed any of the physical wiring, only thing I've changed is that I'm using RSLogix Micro Starter as opposed to RSLogix 500 Starter. I spoke to a Rockwell technician about this and he said that there shouldn't be any problem, as I haven't done anything wrong. So I now ask everyone on this forum if they could help me out a bit.
  2. Hi all,I'm completely new to ASCII and trying to figure out where I'm going wrong here.Application: I need to send 2d barcode data to a KGK Jet model CCS3000L Inkjet printer. Only protocol possibility is ASCII. PLC I have is a Micro850, and the only port option for ASCII is the serial port. I modified one end of a 2707-NC11 cable to connect PLC TxD to printer RxD, PLC RxD to Printer TxD, and PLC SG to Printer SG. I jumpered CTS and RTS at the printer connector, and the 2707 cable I'm using doesn't have wires on the Micro850 CTS or RTS pins.Printer company verified that I can just jumper RTS and CTS on their side and not connect their DTR and DSR pins (since I'm not using hardware handshaking). I don't really need any flow control for the application ( I don't think...again, ASCII noob here).Do the CTS and RTS on the PLC side need to be jumpered? Does the DCD pin need to be jumpered or connected to something if I'm not using handshaking?I downloaded the Micro800 ASCII read and write functions and function blocks from Rockwell library, and they seem to be working, except that I keep getting ABL error id "7". This error states, "Cannot complete ASCII send or receive because channel configuration has been shut down using the channel configuration dialog box." I have the serial port enabled and configured to ASCII, no handshaking, baud 9600 same as printer, no parity check, 1 stop bit, character length of 8.Any help in pointing out what I'm doing wrong or things to try would be greatly appreciated!   ASCII_TEST.ccwsln
  3. Motion Control

    Hi Everyone.   I have been tasked with changing out an older Flex Drive servo drive to a more modern Micro Flex drive in a machine that has an Omron CQM1H-CPU51 PLC.  I'm having a few issues but hope that i can gain some clarity around at least one of the hurdles Im facing from here. Biggest issue for me at this moment is My work hasn't yet purchased a programming lead for this PLC (or even the bits required to make one myself) but i have a feeling the control for the Servo is done via motion control in the PLC.  Question here is, if changing from one servo drive to another type, will the motion control code need to be updated to work with the new servo drive?  I have very limited experience with motion control itself at this stage so I'm a bit lost when it comes to these sort of details. Regards Kiwi_man82
  4. PLC is old one, but I need to add one feature, Signal can be very short and when I get it I want to stop auto mode. I am afraid that signal can be so short and skipped by normal input. How I can set input as an interrupt input. I read that PLC has events processing and it can be triggered by " inputs 0 - 3 of position 1 module, on rising or falling edge"  - in first slot I have card TSX DMZ 64DTK. ( 32 inputs and 32 outputs) is it true ? -  and how I associate it. Maybe I create new Events and as an input I use f.e %I1.0  or I configure it somewhere?   thanks for help     
  5. Hi! I'm using RSLinx Classic, RSLogix Micro English and RSLogix Emulate 500 to emulate a Micrologix 1100 Series B. I'm able to run, program and simulate different input and output with the emulated PLC. Everything works fine. My problem is that I'm writing a program using the nodePCCC library (https://github.com/plcpeople/nodepccc) and I'm not able to connect to the emulated PLC using the address 127.0.0.1 and the port 44818. I tried  running 'netstat -a' on Power Shell and I found out that the port 44818 is not being used.  Could someone help me identify what I'm doing wrong?
  6. Hello all, I am working on a project where I am communicating with a Mensor CPT6100 pressure transducer using a Micro-850 PLC. For this, I have used an AWA instruction to write some ASCII characters to the sensor. The sensor then responds to the write instruction by sending ASCII characters to the RX buffer and I used ACB and ARD instructions to read the ASCII characters. Now, I have set the ACB trigger type to 0 (msg triggered only once) and it successfully reads from the sensor. However, when I set the ACB trigger type to 1 (msg triggered multiple times), I do not get any reading in the ARD block. As a matter of fact, the ACB Q bit switches off every time the program is executed when the trigger type is set to 1. I am trying to get continuous readings from the sensor, but when the trigger type is set to 0, the program latches on to the first and only reading and it won't change. My question is, how can I change my program so that it can continuously and autonomously read from the sensor without me having to manually trigger the AWA and ACB instructions every time. I am attaching the program to this thread for your reference.  ASCII_Test_Copy.ccwarc

  8. Hello - we run a car wash that is controlled by a Modicon TSX Micro 3721001. It is indicating a CPU fault. I've attached a picture of the unit in place, with the LEDs lit. I have ordered a new base unit (2nd picture). I haven't tried it out yet, but it is tested working. I am hoping a base unit replacement will solve the problem, but wondering if it it possible the problem could be in the modules? I did not order those but now wondering if I should have... If the issue could be with the modules, is there a way to test which one it would be so I won't need to order all 4? If it coult be a module, I might order that now as I am in a rush to get back in service. Thanks for any guidance! Andy
  9. We have a carwash automatic controller board with an Eagle Signal Micro 190 PLC.  The program has been reloaded after power outages from a MX207l1 EEPROM Memory Transport Module for over 20 years.  Suddenly the reload isn't working -- either the MTM lost it's program or the socket has worn out over the years.  Anyway, the program can also be loaded via a 9-pin serial cable from a PC.  In trying that, we've found that the program the vendor gave us on the PC doesn't match that on the MTM.  Testing shows that only one output is incorrect.  We simply need to change output on O22 (broken trace on the board 20 years ago) to O20 (which would then match the MTM code).  I am a software engineer, but have never used ladder logic in a PLC.  I *think* I have changed the output, but maybe I just changed a comment.  [Testing requires powering off the carwash, with loss of $$ if we can't get it back up, and $80K expense for total failure, so trial-n-error isn't feasible.]  (1) Can anyone discuss what I did with me so I have a better idea if it will work or not?  (2) Is there anyone in the Atlanta area willing to look at this?  Thanks for reading!
  10. I am trying to read data from a Micro 850 into my L18 (V 30.11). I have never set up an ethernet bridge between these 2 components and i have been up against a wall since starting. I have the MSG blocks in my routine but i am obviously configuring either the bridge, MSG instruction or something wrong. Any help will be GREATLY appreciated!!!
  11. Is it possible to communicate from a PC program to PLC program for reading inputs and setting outputs? How can it be made ? is it possible to do from TER connector or AUX connector , without special comm module?
  12. Hi everyone, Recently, I started working with the Micro820 Controller Embedded I/O. My project is simple : when the output _IO_EM_DO_00 is set to true, an LED light turns on. But, even though it's super simple, I can't make it work. Here's my setup. If you need more information, feel free to ask anything !
  13. Hi everyone ! I have a little project wich involves communication between two Micro820 controllers via TCP/IP. To do that, I started to work with TCP/IP socket. Within CCW (Connected Components Workbench), I tried to create a new socket instance using the instruction SOCKET_CREATE and set the socket address to 127.0.0.1:21. Basically, my computer through the FTP port. The problem was that it couldn't create a new socket instance (error variable is set to TRUE and status is set to 4, wich I don't know the meaning) because I didn't have a server-side application that listens to TCP/IP socket requests. That said, I found an open source application called SocketTest that listens for TCP/IP socket requests on a specified IP address and port. So, I started a listener on the following address : 127.0.0.1:21, but the error variable is still set to TRUE and status is still set to 4. So, my questions are : Is my IP address OK ? Is my port number OK ? What means the status code 4 ? Is SocketTest doing what I think it does ? Do I need to do something else before using the SOCKET_CREATE instruction ? Thank you in advance for your help !
  14. Hi everybody, Recently, I started working on a project. I want to develop a program for a Micro820 controller (2080-LC20-20AWB) using CCW (Connected Components Workbench). I built a little motor circuit for testing purpose. However, after building the program and downloading it to the controller, I tried to connect to my controller via CCW, but I can't. When I click the button "Connect", CWW crashes OR a window saying : "The controller has unnacepted changes" appears and asks me if I want to "Download current project to the controller" (wich I already did) or "Upload the project in the controller to overwrite current project content" (wich is grayed out). When I choose to "Download current project to the controller", CCW starts downloading the resource, but fails. In the "Output" window, there's a line saying : "Download failed for Device:Micro820: An error occured while reading from GETACTIVERESOURCELIST.". The problem is that there's no documentation at all concerning this error. I even tried to reinstall CCW, but it didn't fix the problem. I joined some images so you guys can see what I'm talking about. Don't mind asking for more details !

  17. I'll try and keep this neutral and not degenerate into a rant, but my recent experiences with the AB Micro 850 have been less than heart-warming and encouraging.  We recently purchased a production line for my place of employment from a trio of OEM Equipment builders.  All were supposed to use AB ControlLogix or CompactLogix PLCs.  However, two of the vendors called purchasing and said "let us save you some money, by using the Micro-850 PLC Rockwell's latest and greatest offering".  And our purchasing bought it.  So this week we brought in a Rockwell Premier System Integrator to add 9300-ENA units to these machine so we could collect SCADA Data from them. Now in full disclosure these were CCW version 6 not the latest and greatest 9.1,  So we came to machine 1 a micro 850 and uploaded, saved a copy for safety, then changed the Gateway  from blank to the NAT device IP and downloaded.  Machines on our SCADA Net could now see the Micro 850, but the machine it was in wouldn't start or communicate with the Component Panelview.  Turns out that thing was in remote and came up in program.  Chose run and all appears well.  Go on and do machine 2 another Micro - 850 and it went equally flawlessly.  Our downtime window was up so we started making product.  Only one problem the previous maximum speed was unattainable.  As a matter of fact several configured variables were at their Initial Factory State rather than the state they were when we shut down.  SO HERE COMES BURN NUMBER ONE.  Upload and Save only gets the logic not the variables or the values.  You must export the Controller and each programs variables to a separate excel file to have them around to restore.  That means 1 upload and 15 exports per machine backup and no word of this "FEATURE" in the tech database.  Now today we got a window to do the third machine also a Micro-850. This time we went to program and changed the Gateway without downloading.  Went back to run and all was well in CCW, except the NAT couldn't find the Micro-850.  Blowing the project totally away and doing an upload we learned that the Gateway was not there.  So we did the 1 upload, 15 exports, 1 download and 15 imports and this time all worked fine.  SO HERE COMES BURN NUMBER TWO.  So now we try and place message instructions from Machine 1 to Machine 2 in place and nothing will communicate.  Now before you think we're total fools we had to Micro-850's talking to a Compact Logix on the shop bench just fine when they were all in the same subnet.  But when we placed NATs between them nothing works.  Hopefully our SI will sort this out over the weekend and I'll post that answer later.  SO HERE COMES BURN NUMBER THREE.  We've decided it is in our best interest to flash our Micro-850's to version 9.1, but given the Micro's track record we decided to flash a spare first and swap it in.  Only one problem, the Micro-850 is either such a hot commodity or poor unit that you can't get one for at least 2-3 weeks.  ANd FINALLY BURN NUMBER FOUR.  Trying to troubleshoot this week I wanted to force an INPUT on; only there is no right click and force option.  It is called variable monitoring and you must lock and un-lock.  It has been FORCE for two decades, why change what we call it.  Really did we need to make this more complicated.   OK I am done.  I will not knowingly spec or buy another 850 in my Plant.  Enough said.  Control and Compact Logix only.
  18. Hello,  I am getting this fault when I am trying to load one of my program and set to run mode.  I have the same plc and I have not had this problem again. 1761-L16BWA Any suggestions ? I think this plc is older than the other I have. 
  19. I am in the learning phase of HMI and PLC programing and am trying to use some of the hardware that has been donated to me. I have an AB panelview 300 micro terminal and a Micrologix 1000 Plc (they are not tethered yet). I have constructed a small test board with everything mounted to it and have successfully written and downloaded a simple project to the plc with timers, etc.   Now I need to find a way to program the terminal to make changes to the program.   I am looking for some free panelbuilder 32 or anything that will allow me to program the terminal and use it.   Can anyone help me? All help will be greatly appreciated!
  20. Hello, I have a question if anyone could help. Need to communicate Enthernet/IP a PLC Micro 850 to an HMI Panel View 800 4.3'' . Some examples would help a lot. 1- http://ab.rockwellautomation.com/Programmable-Controllers/Micro850#overview 2- http://ab.rockwellautomation.com/graphic-terminals/2711r-panelview-800-graphic-terminals#selection thank you
  21. I'm getting ready to use a 4" PanelView800 with the Micro820, this is my first time, can anybody recommend a good Video, tutorial? I just going to display about 4 or 6 lines of "Instructions" and then have just 2 "Touch Buttons" a START & FINISH. Thanks
  22. I would like to create a Ladder logic file to do the following: When an Input is pressed, I want to start a Timer. When the input is pressed again, I want to write the Elapsed time of the timer to a word, and then reset the timer, and start the timer again. I tried putting a pulse Rising Edge Contact to start the timer, and a reverse contact (XIO) on the input to keep the timer going, but this only times half of the time. This is my first project with the Micro810 On RSLogix, I can reset the Timer, so I don’t have this dilemma. Any pointers?
  23. Hi, I have AB Micro820 PLC (2080-LC20-20QBB) which, acc. to the specs, can be both Ethernet/IP master and slave. I need it to be a master(scanner) and communicate with a KEYENCE DL-EP1 module, which is Ethernet/IP slave(adapter), but don't see any way to make that happen. How do you declare/configure Ethernet/IP slaves in Connected Components Workbench and how do you add slaves to your CCW project? I have an EDS file for the slave, but what to do with it? I imported it (have no idea where) with the EDS hardware installation tool which reported all was OK, but do not see the slave anywhere in the CCW. I only see in the Device Toolbox > Discover, but the only available option there is to remove it :) Thanks for any suggestions. Peter
  24. I am trying to use my RFIDeas pcProx plus reader with my micrologix 1400. I know that the 1400 can send and receive strings. I want to read in the id number from the reader and send it to an external database. Can someone please point me in the right direction? Thank you
  25. Hello I was searching the internet and I came up with this forum. Im excited to be part of it as a newbe I have a question on a micro 1100 with pto outputs to a stepper drive. The drive I'm using is anaheimautomation MBC25081TB - Stepper Drivers with DC Input. I was told that the sourcing output of the 1100 would work fine with the clock input on the drive. this is how I wired the drive and this is how the drive looks. Im not even sure what Im doing I have the plc set up and see it pulsing but for the life of me I can't get the drive to move. Can you please tell me the errors of my ways. Im very new to this and its killing me trying to get this running.
