I'm trying to find out how to interpret a symbol file created by CoDeSys.
I'm working with our local Beijer HMI office to try to get them to write drives so I can import a symbol file in the HMI and have access to the variables in the PLC.
I know I have done this with the Moeller HMI's and their X-Control PLC and also with the Bosch Rexroth HMI and IndraLogic PLC.
Does anyone know how this is accomplished? Is is a form of OPC? Is it straight DCOM messaging? Or something else...
Thanks,

When you talk about HMI, I assume its not the built in HMI?
If not then a solution is to use a CoDeSys gateway installed somewhere.
CoDesys then has a OPC-server using the symbol-file that connects towards the PLC using said gateway. So our application would use OPC.
Other field-busses may offcourse also be used if supported by your target/HMI.
Lastly you could use the CoDeSys protocol to communicate directly to the PLC. I dont now if theres a document or any sotware components available for this?
