I'm trying to get Ethernet/IP communication working to a Festo CPX valve bank using an FB32 from a non-Rockwell PLC (Schneider/Elau PacDrive3). I have the status bits turned on, one 8DI and six MPA2S modules in the bank, which should result in 3 input bytes and 6 output bytes.
I imported the EDS file and created an I/O Connection with the correct number of inputs and outputs bytes to match my valve bank. When I go online with the PLC, it says everything is fine and working, BUT it only returns zeros on the inputs and if I force an output, no valves turn on. If I connect to the bank with the Festo Maintenance Tool, it correctly reads the inputs and sets the outputs.
The connection path is: 20 04 24 66 2C 64 2C 65 and the trigger type is Cyclic with RPI of 20ms. O->T is 6 bytes, mode is Point to Point, type is Fixed, and transfer format is 32Bit Run/Idle. T->O is 3 bytes, mode is Multicast, type is Fixed, and transfer format is Pure Data.
For comparison, a working connection to a VFD has a connection path of 20 04 24 05 2C 64 2C 65 (only difference is 4th pair is 05 instead of 66) and all the same settings except for the input/output sizes.
Any help would be appreciated.
