Hi all;
I am having problems connecting to a Schneider Electric PLC.
I've had a real good look around the web and the forums and am still unsure why I cannot resolve this issue, so hopefully someone here will be able to point me towards a thread with the answer or give me some direction.
The PLC in question is a Schneider Electric TSX P57 3634M processor/ETY Port comms combo card. I am unable to connect via:
- TCPIP using a crossover cable or straight cables to a hub/switch
- USB/UNITELWAY using the TSX CRJMD25/TSX CUSB485 cable
I have no other cables, etc to connect with.
USB / UNITELWAY:
I have connected to both the TER and AUX ports, setting my cable in turn to TER Direct, TER Multi and so on, without luck. I have checked the driver settings, ensuring via Windows Device Manager that the COM port number in Unity Pro / Driver Manager matches that of the laptop. I have tried various COM ports (e.g. 1, 3, etc.) but none seem to work. Also I have tried multiple BAUD rates and so on as suggested online but again, no luck. I have set the address to SYS/USB and SYS/UNITELWAY but neither has worked.
TCPIP:
I have power-cycled the PLC to reboot it, which has returned it to it's default IP address (which I reconstructed as 85.16.26.177 from it's MAC address, ending in 1A-B1). Setting the laptop to 85.16.26.180 (subnet 255.255.0.0) has enabled me to ping it succesfully from the command prompt within Windows, however I am still unable to connect to it from the 'set address' window in Unity Pro. I am also able to see the PLC in Rockwell Automation's 'BootP' software (I can view it's MAC address and reassign it to something else, which I can then ping successfully from the command prompt once the laptop is set to a compatible IP).
I have removed all I/O modules from the rack in case they are causing some kind of conflict, but again this has not helped.
In frustration I have tried both Unity Pro L and Unity Pro M, even though that shoudln't matter for the sake of establishing a simple connection..!
I did see an obscure mention somewhere suggesting it's because I am using an 'extended' rack instead of a 'non-extended' rack (my rack is part number TSX RKY12EX). I have tried with and without terminators on the ends of the rack and it makes no difference.
Is the rack/backplane the cause of my problems? I have no other spares I can try for this PLC.
Any help you can provide will be greatly appreciated! There's a lot of inof here, and I hope I haven't missed anything out. It is doubly confusing as I am able to ping the PLC but Unity Pro will not connect.
Many thanks, Jake
