I have a Waukee temperature controller that has an internal limitation of only allowing a single TCP master connection. Problem is I need to have two TCP Masters talk to it and request it's atmosphere value.
My two TCP Masters trying to talk to the Waukee controller as a slave are a Proface HMI and an IBA data logger. Ideally I think if I had a micro PLC, I would have that read my device data in and then the other Masters in the circuit can request the data from the PLC...perhaps that would be best?
Wondering if there is a cheaper aleternative like some kind of Field Server, IO controller or Modbus gateway perhaps from MOXA or another manufacturer that would perhaps provide this function; brokering requests from two masters while said gateway device only requests from Waukee controller (slave device) as a single TCP request and duplicates the data received back to dual TCP Masters...
Would anyone be able to recommend devices for that purpose or am I best implementing a small Siemens 1200? Thanks ^^
