  1. Walt Boyes reports that Dick Morley, the father of the PLC died on October 17th. http://www.spitzerandboyes.com/a-legend-passes-dick-morley-died-today/ Wikipedia has been updated and summarizes Dick's contribution to the automation world: "Richard (Dick) Morley (died October 17, 2017) was considered the "father" of the programmable logic controller (PLC) since he was involved with the production of the first PLC for General Motors, the Modicon, at Bedford and Associates in 1968. The Modicon brand of PLC is now owned by Schneider Electric. The PLC has been recognized as a significant advancement in the practice of automation, and has an important influence on manufacturing industry." https://en.wikipedia.org/wiki/Dick_Morley An article gives some history of the process Dick went through in the early days https://www.automationmag.com/features/the-father-of-invention-dick-morley-looks-back-on-the-40th-anniversary-of-the-plc.html
  2. 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?
  3. Hi everyone, I'm a newbie in the ladder logic programming languages. For my thesis project I've to develop a scenario but I'm stuck with the creation of a socket connection from the Modicon M340 PLC to a server for transfer continuous data given from sensors or similar. Does anyone have a sample program that could have such a functionality so that I can change it based on my needs? Thanks in advice for any further reply!
  4. Hi all, I have a problem when I upload program from PLC TSX P57104 to modify some parameters and download to PLC again but I cant because the PLC have error is "write protected-catridge".I tried using "online modification" to change the parameters but the same error appears "This action is forbidden because Flash catridge: write protected-catridge".

  6. Trouble Wiring a Simple LED with a Micro820 Controller

    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 !
  7. Hi all, I am working at a company that has a paint booth that is rather outdated. It has 10 robots in the booth and the safety circuit for each robot is controlled by a Modicon Nano TSX PLC. I have managed to successfully download the programs with the PL7-07 software (managed to do it on a laptop with window XP). We have some back up programs that were taken roughly 4 years ago and I would like to load them both up on the software and compare them. Is this function possible and if so how do I do it?   Thanks  Shane
  8. Socket communication with Micro820

    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 !
  9. Can't connect to Micro820 controller via CCW

    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 !

  13. ASCII Code 8 Byte In Twido

    Hey Guys!!!! I'm trying to use ASCII 8 bites in TWIDO PLC and on MOD BUS TCPIP it connected to WinCC , where I'm trying to read the ASCII in as a STRING char that to in 8bits. The problem I'm facing is that it is getting swapped like if I'm writing VA in PLC then on SCADA it is showing AV. In WinCC there is no setting for word swapping. Therefore Kindly help me for this in plc end
  14. Hi guys, I have tried almost everything and ran out of option on how can I successfully connect modicon m34020 processor using mini USB with unity pro, I am working in Windows 10 and selected everything possibly correct I can, like setting address to USB, and "SYS" in Set parameters, I have USBplc driver installed and it shows, "disconnected" and local and remote id emptly fields. In my device manager, I can see a question mark on the processor driver "BMX CPU" and when I try to update/upgrade/fix it it simply goes to nothing. While the Unity Pro shows the error "this isn't the right address or the plc is too busy or off". Please advise, if i am missing something. thanks in advance.
  15. 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.
  16. 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. 
  17. Hello,I am trying to use ProWORX NXT to view the logic of my Modicon Quantum 534 controller online. When I try to go online with it, it always times out. I am using a TCP/IP connection and my PC is in the same subnet as the controller in question. I can ping the controller's IP address just fine and when I use ProWORX NXT's Net Scan function, it recognizes that there is an Ethernet connection at that IP address but doesn't recognize it as a Modicon controller.Weirdly enough, my PC can connect to another Modicon controller of the same type and in the same subnet just fine.Can anyone help me with this issue?
  18. 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!
  19. Hello, I got a new work job to design a cycle tester for a mechanism to make sure will work for at least 5000 cycles open - close.

I have a TM221C16R PLC from Schneider. please help me with some instructions. the cycle tester will have a start pushbutton, stop pushbutton, door open switch, one air cylinder with solenoid to push and pull and a counter. Thank you, Romica
  20. I am having trouble loading the configuration into a Micro984-230. I lost an old M84-002 PLC. I have the program. I purchased a Micro994-230 replacement. I lost my cable, so I made a new one. The only software that I have still running is Updoc 4.30b. I tested out my cable and Updoc by connecting to a 984-381. Everything worked fine online and offline. The error I get during the configuration loading is communication error 13. I have no idea what that is. Perhaps I can't do configuration loading with Updoc. I have Modsoft Lite  working but I do not think that it works with this controller. It is for MIcro and Compact controllers. I may have modsoft and taylor kicking around but I do not know if they are installable or not. I hope I can find out if my config is improper, I have used the wrong controller setup file (used Micro984), or where iI can have the config loaded for me? I also do not know if this used controller is functioning correctly.
