We have our HMI (IntelliMAX) that will poll data from 300 PLCs. The communication will be done thru a radio MDS Transnet. From the HMI to the Master radio is PROFIBUS DP, and the same in the slave radio to the PLC. We will get an OPC server for PROFIBUS to be able to talk to the PLCs.
Question is:
1. Does PROFIBUS take care of the polling when is radio based? The OPC server cannot request all the data, otherwise will take all bandwidth.
2. Normally the radios are protocol transparent? Meaning that I can send data to other devices using PROFIBUS or Modbus. Obviously one radio only will send data for one protocol, in this case it will be PROFIBUS.
