Has anyone connected an06 to a Watlow ex-zone controller? I am trying to communicate through port 2 on my 06 to an EZ-Zone controller that has Modbus communications. I am trying to pull the input values from th eWatlow controller to my 06. Any help would be appreciated. Paul Ribich

06 to Watlow EZ Zone
It looks like the value you want to read is at Modbus address 360 in the Watlow controller and the value is a Floating point data type. If you are using the MRX command you would have the following:
Port # :K2
Slave address: K ?? ( Whatever your Watlow address is set to.)
Function Code: 03- Read Holding Registers
Start Slave Memory Address: 40360 ( 360 per the EZ Zone manual)
Start Master Memory Address: V????(wherever you wish it to go reserve 2 words)
Number of elements: K2
584/984 data format
change Exception response buffer to a unique address.
Since it is a floating point I am not sure what order it will come in. ( low word/ high word or high word/ low word) but it looks like there are provisions in the Watlow controller to change the order if needed.
