You can connect the Modbus port of LUCM module (Multi Functional Control Unit) of TeSys U controller with PLC in order to access all the registers, except the registers from 680 to 705. To access these registers for write function, you need a communication module depending on the protocol.
Therefore the command registers (like Start/Stop) 700,703,704,705 cannot be accessed for writing by the PLC via LUCM Modbus port. However, you can read and monitor the values of Tesys U controller.
