Hi,

By using serial Modbus protocol you can control watlow devices.for that you have to use Opto’s Modbus Serial Integration Kit for PAC Project. and by using that you can control this watlow controller.

we tried that with watlow CLS204 and we can sucessfully communicate this watlow controller using PAC.

check out http://www.cszindustrial.com/documents/manuals/WatlowF4_UserManual.pdf. Chapter 7 gives a summary of the modbus registers on the unit. Coupled with the Opto Modbus integration kit you should be able to extract whatever information you require.
