Jevan Posted December 19, 2022 Report Share Posted December 19, 2022 Hello I have recently started a new job, and been told "you know siemens/tiaportal, so work out how this unitronics stuff works". Arm moving around big chunks of metal, process controlled via PLC. All installed by external company some time ago. I cannot physically check what is actually installed at the moment as it is in 24h usage, but want to be prepared for when an opportunity arises. The project parts list includes a "V130-33-T38", a "Ex90-DI8-R08-C1", and a whole load of switches etc. The parts list makes no mention of an I/O expansion for the V130, but given that it needs one, I assume that one is installed. It looks like they are likely to be connected over RJ45. I have ordered a MJ10-22-CS25 and MJ10-22-CS35 (and installed drivers and vislogic) to hopefully be able to create a copy of whatever programming is on the PLC. Questions: Is the I/O port in the V130 specific to the EX90 expansion? Could it be used for other things like copying the programming off the PLC? Can any RJ45 cable be (potentially) used? Any issues/complications to watch out for when copying the programming off? Can't do a test run in a safe environment to check that communication works. Basically, I have no knowledge of the hardware, and no experience with the software, and want to be prepared as I will have limited time to see how it is physically set up, and to try to copy/backup the PLC data. Thank you. Quote Link to comment Share on other sites More sharing options...
