Communication Modules

Direct connection of the CM-232 to a PC or PLC
The CM-232 Communication Module enables a direct connection between a 9-pin D-Sub connector
(X310) of the CM-232 and the serial interface of a PC or PLC.
The configuration of the installed communication module is carried out using the VPlus PC-Software or
using the Operator Panel.
With CM-232 the connection to the PC or PLC is made via a RS232-Connection Line (1:1 occupancy).
Direct connection of the CM-485 to a PC or PLC
For the direct connection between the 9-pin D-Sub Interface (X310) of the CM-485 and the serial
RS232-Interface of a PC or PLC, install an RS485/RS232 interface adapter on the signal line.
The configuration of the installed communication module is carried out using the VPlus PC-Software or
using the Operator Panel.
Attention!
The transmitter and receiver must be set to the same transfer rate (baud rate).
The set baud rate applies to the CM-232 and CM-485 communication modules.
Work Steps:
• Mount the CM-232 / CM-485 Communication Module onto the frequency inverter.
• For the CM-232 Communication Module:
Connect the CM-232 and PC with an RS232-Cable.
•
For the CM-485 Communication Module:
Connect the CM-485 with a RS485-Cable to the RS485/RS232 Interface Adapter.
Connect the RS232-Connection of the Interface Adapter with the PC/PLC.
Setting the type of Protocol
The factory setting of the CM-232/CM-485 Communication Modules is the BONFIGLIOLI VECTRON
standard protocol (VABus). Communication with the VPlus PC-Software is only possible using this pro-
tocol.
The VABus protocol enables the operation of a straight Master/Slave-System. The Bus-Master can be
a PC, a PLC or any arbitrary computer system.

Installation Notes

• For the RS485 bus cable use a twisted, shielded cable.
• Implement the shield as a braided shield (not a foil shield).
• Connect the cable shield surfaces at both ends to PE.
• The connector pin assignments of an RS485-Cable and an RS232-Cable are different. No data
transfer is possible if the wrong cable is used.
