Has anyone had any experience with a Watlow to Red Lion modbus comms setup? We have a pair of Watlow controllers that I want to set up to comm with a RL CSMSTRSX using modbus TCP/IP. The Watlow units are doing their thing, controlling a furnace, but I want to monitor them. I will not make any writes to the Watlow.
I have set the RL 2nd protocol for "Modbus TCP/IP Master" and I can see (display on the PC screen) that hex data and 16 bit data gets to the RL but I can't see the real data (temperature) in decimal form. I have tried using the Word, Long and Real settings on the tag mapping with no success.
I have used CAS's Modbus Scanner to read the Watlow data so I know I'm getting all the data from the Watlow to my ethernet. CAS does an "Auto Update" poll and the data stream follows the readings shown on the front of the Watlow so, again, I know I'm live to the ethernet. I also know that the RL is getting the hex and 16 bit data since it too shows what the Watlow shows.
I really just need to show the temperature in decimal form, that is being sent by the Watlow to the RL, on the PC screen. I'm sure I am just missing that "one little thing"! Any help would obviously be appreciated.
