Hey everyone,
Working on a system with a newly installed ControlLogix 5571 (Rev 24) which replaced an old SLC (5/04 I believe). The SLC originally communicated I/O back to a DCS integrator PLC, with a PLC-5 piggybacking onto it over DH+. The DCS integrator PLC is another ControlLogix, but it's a 5562 (Rev 15.04), and I seem to be having a bit of trouble talking to the integrator PLC remotely. When I go into RSLinx, I can see the integrator PLC by going into the new PLC through USB, then out of the DHRIO card on Channel A, which shows me the PLC-5 and integrator PLC, but I can't go online with the processor. It gives me Error 701-8004250A, and says "No open connection." There are a fair bit of MSG instructions happening in the integrator PLC, could that be hogging the connections?
Thanks
