Description
PM866 3BSE050200R1 Modbus Protocol Controller
Some of the CPUs of the PM866 3BSE050200R1 series PLCs are equipped with PROFIBUS DP master/slave interfaces, so we can utilize the PROFIBUS bus transfer protocol to acquire field temperature signals in bulk.PROFIBUS -DP is used for high-speed data transfer at the field level. The master cyclically reads the inputs from the slaves and cyclically sends the outputs to the slaves.
The bus cycle time must be shorter than the master (PLC) program cycle time. In addition to cyclic user data transfer, PROFIBUS-DP provides the non-cyclic communication required by intelligent devices for configuration, diagnostics and alarm processing. The temperature signal of PM866 3BSE050200R1 can be collected centrally by inspection.
