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 Moeller PLC devices the following communication drivers can be used:

1. OPC server

For communication of the PROMOTIC application with Moeller PLC devices the OPC server can be used that is protected by the HW Key.
The OPC server can communicate with Moeller PLC devices:
- via the computer's serial port (by the SUCOMA protocol).
- over the phone modem.
- by the 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.

Trade terms:
The usage of the PmaOpcDaClient object requires purchase of the "PmOPC" licence. When developing the application in the freeware mode PmFree, or with development environment and while testing it in runtime, this component is always functional.

2. DDE server - obsolete method

The DDE server supports the communication by the SUCOMA and SUCONET protocols. It goes about the serial communication.
The DDE server can be set as a Master (the most used solution) or a Slave.
Caution: The DDE server allows to communicate only over one communication port to the PC (COM1 or COM2 can be chosen).
