  1. Macro Burned by the Micro 850

    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.
  2. Micrologix 1000

    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. 
  3. Panelbuilder 32

    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!
  4. PLC Micro 850 and Enthernet

    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
  5. 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
  6. Micro 810 Timer Reset

    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?
  7. 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
  8. Hello A-B Guru's, I have a small station with a Micrologix 1000 controller in it. Keep getting a "Major Halt Error S:1/13, Invalid STI interrupt set point. Refer to S:30." It is a very simple program, not using the STI instruction. Have a filter on the processor power. Nothing crazy going on, on the station, no big coils, etc. What can I do to prevent this fault from occurring? Can I add a line of code to always unlatch S:30? What should I do? Please help.
  9. Hey guys, so for a while I've been wanting to get a little PLC for home that I can play with and just have some fun with. I don't know exactly what I will do with it, I mean I live in a 1 bedroom apartment in Minneapolis, so I don't exactly have a large workshop to set up projects, but maybe some home automation type stuff. I'll probably set up a little test board with din rail and terminals and just mess around with it when I get bored. Anyways... so I wasn't sure what to get. I've always liked Allen Bradley, but the licenses are so expensive, obviously. But now with my current job I have to take my laptop home in case someone needs support on one of our machines, so I have RSLogix5, 500 and 5000 software/licenses installed on my laptop, so I can just use that. So I was looking at my options. I was thinking about getting an Aurduino or Raspberry Pi, but I kind of wanted to stay with Allen Bradley since that is what I use at work, and I may as well learn as much as I can about that. Well anyways, 2 nights ago I had a few too many drinks after work and I was browsing eBay for used PLCs and I bid on/won a MicroLogix1000. It seemed like a good idea at the time, it says its fully functional, it has free shipping is only $85, and since I already have the software... So what are your guys' thoughts on the MicroLogix1000? To be specific, the one I bought was the: 1761-L32BWA MICROLOGIX-1000 Besides the software and the computer cable, is there anything else I will need? I don't need expansion cards with this, unless I want, because it has i/o built into the controller, correct? I will just need a 120VAC and 24VDC power supply? Thanks!
  10. Micro 1400 with an RFID Reader

    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
  11. Micro 1100 to a stepper

    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.
  12. S7 200 Fatal Error

    Hi guys, I have an S7 200 CPU 212 PLC and it is in system fault condition. I am using MicroWin V4.0 and I am connecting via 6ES7 901-3DB30-0XA0 USB PPI cable. I have followed the steps in the help file to find the fault code but cant seem to find how to rectify it. The code displayed in the fatal errors section is: '5 Permanent Memory error on user program' I was hoping that I could upload the program to my laptop, clear the PLC memory, then download the program back to the PLC. This does not seem to be possible and I am now stuck with a PLC in fault. I do not have a backup copy of the program so if I clear the memory I will be stuck. Any advice greatly appreciated
  13. Ken Roach already answered this question for MicroLogix 1200, I'm trying to find the same answer for MicroLogix 1000. DF1 half-duplex communication gets dropped with MicroLogix 1000 slaves. I monitored the data, and found the slaves stop sending ACK, and the master stops sending ENQ. Slaves still send valid responses, but these responses are ignored by master because the ACK is not present. Power cycle solves the problem, but that's a hassle to drive out to remote sites. Power cycle to master sometimes solves the problem, but not always. Messages are initiated by the master, not by the slaves. Rockwell support said the only solution is to cycle power. Ken's approach was to monitor CS0:17, if it changes issue an ACL command. See previous topic: http://forums.mrplc.com/index.php?showtopic=22686 Thank you!
  14. Micro 810 application.

    Hello all, I'm quiet new to control and logic systems, I'm still learning. I have to develop a circuit/logic for an application. I was wondering if Micro 810 can be used for this & the objectives of the application are: 1. whenever Signal A(0-24V) is high for the first time in the cycle and Signal B(0-24V) goes high then the solenoid X(24V) should be ON. 2.when signal B is low then the solenoid X should be OFF. 3. If in an instance signals A and B are opposite to each other for more than 2 seconds then a signal should be sent to E-stop. If not Micro 810, what are the other products that are suitable for such application? I know this can be done by normal relay board and some timers; I want to use a controller for this if its cheaper in price. Regards, _SKR
