I don't know the best place to start, so....
I have a piece of equipment from a vendor (large blower from EBM) that has Modbus capability.
I have a SNAP-PAC-R1 controller on a 16 position rack and have a SNAP-SCM-485-422 module in one of the locations.
I have downloaded and started to play with the Modbus integration kit.
The blower requires Modbus RTU communication, 19200 baud rate, even parity, 1 stop bit, and 8 data bits.
As I said, I have tried playing with the Modbus integration kit settings but have been unable to get any useful information through the module.
What I am really looking for is some advice on where to start to learn what enough about Modbus to get started with this.
I know this is vague, but any help/pointers would be appreciated.
