  1. http://accautomation.ca/now-you-can-have-robust-data-logging-for-free-part-1/ YouTube overview: https://www.youtube.com/watch?v=6Xa2HYVOxE0 Robust PLC Data LoggerWith traditional loggers, software will read the memory of the PLC and store in a local computer. If the network stops or the PLC communication fails then the logging will stop.Creating a robust PLC data logger allows the communication to be stopped for a period of time without losing any of the data for collection. This is accomplished by storing the data locally on the PLC until communication is restored. All of the data is then read without loss. The amount of time that the connection can be lost will be dependent on the memory size of the PLC and the frequency of the data collected.This series will walk you through the steps to create and implement a robust PLC data logger using the following equipment and hardware.

    Hi guys , Greetings to all and a Merry Christmas to the moderators of this forum, I am relatively new to the S7 plc programming but i had some basic troubleshooting and very basic programming while i was a technician over at a MNC running some moulding machines. I wish to rekindle my interest on S7. I wish to simulate the outputs using a simulator so that i can test my ladder programs without the need of a plc controller. I have managed to obtain a S7 software and i have installed it in my laptop running windows xp sp3. The software that i have installed is a S7 V5.4 SP3, no issues in the installation here. And i have also installed a S7PLC Sim Version 5.4. I hope anyone here can guide me on how to test a simple ladder prgrm and see the simulated results. How do i configure my laptop and how to set pg/pc interface and so on? I did try something on my own but when i try to add the plcsim v5.x into the list of modules installed i get an error stating " S7einstx.dll module can't be started. I humbly request that someone here can point me to the right direction or so? Thank you and have a nice day. Rgds Ruben

    There are two Proficy ME projects in the zip file one for VersaMax and one setup for 90-30 CPU364 but is the same for all of the 90-30 processors, but read the Manual GFK-2220 to get the correct port information for your CPU and configuration. They are both working and well documented. They were done quite a while ago but I do not recall what version of PME is needed to open them. It is my recommendation that we all use the latest version. Good luck and have fun with it. R~ <))>(

  7. Hi everyone, I'm facing problems implementing the Easy modbus-rtu master solution kindly provided by PMCR. i'm working with a CJ2M, and i have a SCU41-v1 connected to 5 AC10 series Parker drives, using modbus at Port 1 (Protocol Macro as indicated in the manual- 2 wire). Everything works ok after powering up the system. Unfortunately, after a few minutes, one of the parker drives freezes communication. An hour later....another. And so on. If I reboot the drive, powering it off and on, it starts communicating again. Any ideas about what might be causing this? Thanx.
  8. Hi everyone, I want to connect Allen Bradley 1756-L63 cpu (slave) via RS-232 port to ABB CI-853 (I don't have Prosoft MVI-56-MCM that can easily solve my situation). The only way that I found is application ModbusSlave.ACD (cig-ap129_-en-p.pdf). Do I need AIC+ converter (1761-NET-AIC) or can I connect with cable (DB9-to-RJ45)? Is there another way to make this connection? Regards, Luka
  9. Im trying to control a baldor VFD trough modbus RTU with cp1h/cp1wcif12 using the solution posted here which for me works really fine but the problem comes when I turn on the motor (500hp 440v), the cable gets induced and adds noise to the communication causing errors when reading. I already try to use shielded cable and it gets better but still causing errors. In the solution posted in the link above shows how to connect the cp1w-cif12 by connecting only SDA- and SDB+. So my question is, should I connect FG to the VFD rs-485 ground as well to reduce that noise? Any suggestions are welcome
