Communication with Moeller PLC devices

It is possible to communicate with the Moeller devices as follows:

- by the SUCOMA protocol: serial link, point-to-point connection, the protocol is supported on the programming port at all Moeller devices.

- by the SUCONET protocol: serial link, Master x Slave connection, in the Moeller devices the network card with the SUCONET support is necessary.

- in the Ethernet network (TCP/IP): over the CoBox HW converter.

- over the phone modem: by the SUCOMA protocol

For communication of the PROMOTIC application with the Moeller devices the following communication drivers can be used:

1. OPC server

For communication of the PROMOTIC application with the Moeller devices the OPC server can be used that is protected by the HW Key.

The OPC server can communicate with the Moeller devices:

- via the computer's serial port (by the SUCOMA protocol).

- over the phone modem.

- by means TCP/IP protocol (by means of the CoBox HW converter).

The communication in the Ethernet network can be implemented by means of the CoBox HW converter - to convert the SUCOMA serial protocol to the TCP/IP protocol. For more information - see the technical support.
