I've setup an Omron NX102 PLC with two CIF105 cards communicating with about 40 MX2 VSD's (20 on each card). Generally it works pretty well. I used the attached document to set up the devices. The links on the document to the examples don't work, so I'm unsure if I missed anything. My problem is that every day, sometimes multiple times a day the communication seems to die. i.e I either loose the output to the VSD and nothing will run. Or it all runs but I loose the feedback, as in I get no running signal even though the drives are running causing a fault in my program. I'm at a bit of a loss as to what might be causing the issue. To resolve it, I put the PLC into program mode and back into run mode and everything is happy again. Has anyone had a similar issue or offer any advise? MX2_Control_Serial.pdf

Has anyone setup comms between an Omron NX range PLC and a Sick Flexisoft GENT module. Trying to figure this out. Should be doable, but struggling to get InDataSet1 to update in the PLC. I have a comms error on the Flexisoft module. Assume it's something to do with the size of my tag arrays

Hi there, I'm wanting to connect a panelview 800 to an SLC5/03 the SLC is connected to an 1747-AIC which is run to another 1747-AIC. I'm trying to figure out what cable I require to connect the peripheral of the second AIC module to the panelview. I can't seem to find any reference online. Any help would be appreciated. Image attached to clarify.

Hi, So I have a problem when copying an application from USB onto a panelview plus 700/1000. The copying part from external to internal memory is fine, then I load it into the current application and run it and everything works. Until you restart/cycle power to the HMI and for some reason it reverts back to whatever the previous application that was loaded was. If this has been deleted then a message appears saying the application can't be found. Transferring the application from the transfer utility on a PC to the HMI works perfectly and when power is cycled there is no problem the application sent loads and runs, provided the tick box "Run application at startup" is selected. Has anyone had this problem of a USB transferred and loaded application reverting back to a previous version before, and found a solution by any chance? My current work around is to make sure the new application is called the same as the previously loaded application and that works. However this creates issues with keeping track of revisions on sites. Cheers
