Hi, we have a system that has multiple cabinets using guardlogix point I/O. For some reason that I cannot explain as of yet we sometimes loose ownership on one of the cards and have to reset it. Has anyone experienced this before and if so what was the cause and solution?

Hi, I have a problem with my BC9020 and hope that someone can help me. I managed to set the IP adress of my PLC in the 10.2.5... add a root, run a program and make the PLC working for a while. I then tried another program, a new one... and now that I want to re-read the first program, Twincat System Manager doesn't allow me to enter in the "run mode" and stays in "config mode". It also has lost the IP address I set (10.2.5.....) and came back to the 172.16.22... (manufacturer settings) I cannot determine if the problem is in the PLC Control or In System Manager... This is my method to change the IP *** IP config *** 1) Reset the PLC First I place the end terminal next to the PLC. I set the DIP switches 1,6,7 to ON, power on the PLC and power off. I set the DIP switches 2,6,7 to ON, power on the PLC and power off. I set the DIP switches 1,2,6,7 to ON, power on the PLC and power off. 2) Set my PLC on the same AMS than my own IP (172.16.22...1.1) 3) In System Manager, add a new route 4) change the setting in I/O Configuration -> I/O Device -> Device 2(BX9000) -> clic on BX9000 define "set IP Address" to Manual define " IP Address" to 10.2.5...., the AMS change automatically. Press the configuration button and then Ctrl+F4 (run mode) This method worked but seems not to be the best... If you have any Ideas ? or questions? Thank you in advance Gregi

A SCADA framework is a software platform for creating SCADA applications. I recently wrote an article that can help people evaluating SCADA frameworks. It includes a checklist at the end that is also useful. The article is here: A Software Framework for SCADA Applications The article describes capabilities and functionality of an ideal SCADA framework.

Hi I have a customer who wants to communicate some setpoint information from their Siemens S7 PLC to a CompactLogix L32E PLC. I have installed a Prosoft PLX32-EIP-SIE for ethernet-to-Siemens Industrial Ethernet comms. On receiving a setpoint in from the S7 I then close a loop with some speed feedback in the L32E with a PID. I don't have any access to a Siemens S7 (or software) to test that the comms is working before the unit is shipped, all I have is the CompactLogix hardware. I do have a second CompactLogix PLC / PanelView HMI, but I dont think that this will give me the comms to talk to the SIE port in the Prosoft. I was hoping to have a simple slider on the PanelView to change an integer value to simulate the setpoints coming from the S7. Does anyone have any idea how I might implement this with AB hardware / RSLogix / FactoryTalk?

I need to change the IP address of an existing PLC. Only access I have is remote (VPN). Is there any issue with downloading the same program - with the IP address changed - to the existing processor? Then change the local network range to match, etc...
