OK, I'm having trouble understanding correct addressing to read data from the MB-Gateway Automatic Read registers.
I am reading data from the MB serial slave using an ECRX block, and a peer-to-peer setup in the PLC's ECOM.
I believe I have configured the MB-Gateway to auto-read data from the serial slave.
I cannot read the auto-read data from the gateway into the PLC. Too many "ID"s.
ECRX sends its message to Slave ID 4
ECOM100 has a peer-peer device 4 configured to TCP device at 192.168.5.104, port 502, ID #2 so the read message is sent to serial MB slave #2, which responds. Works fine, but with occasional comm errors.
Gateway Modbus Address is set to 4. I have tried changing to 5.
How do I address the MB-Gateway data space that contains the data automatically read from the serial MB slave?
Any help would be gratfully accepted.
