RS485 and RS232 Interfaces

5 RS485 and RS232 Interfaces
The frequency inverter can be controlled from a PLC or another master device via a serial interface
using the Modbus or VABus protocol. The VABus protocol is required for the parameterization with the
VPlus PC-Software.
The connection can be established via the RJ45-Connector of the X21-Connection or via an optional
communication module.
The following protocols can be selected:
− Modbus RTU
− Modbus ASCII
− VABus
The communication with the VABus-Protocol can be established via:
− the RJ45-Connector of the X21-Connection
− the CM-232 Communication Module with RS232-connection using a 9-pin D-Sub connector
− the CM-485 Communication Module with RS485-connection using a 9-pin D-Sub connector
− the CM-485T Communication Module with RS485-connection using a 7-pin terminal socket
The VABus communication is possible either via the RJ45-Connector of the X21-Connection or via an
optional Communication Module. Simultaneous Modbus communication via the X21-Connection and an
optional Communication Module is not possible
Simultaneous VABus communication
tion Module.
Possible Combinations of VABus with Modbus:
Communication Module
Modbus (RTU or ASCII)
VABus
VABus
Combination Options with the Scope Function:
Communication Module
VABus
Scope Function (VABus)
Scope Function (VABus)
Modbus (RTU or ASCII)
The Scope Function is started via the VPlus PC-Software. The Scope Function cannot be started via
VPlus and an optional Communication Module at the same time.
The baud rates for the X21-Connection and the Communication Module can be set separately.
Note:
This document is not basic information for the RS232 or RS485 serial interface. Fundamental know-
ledge of the VABus protocol and the RS232 and RS485 serial interfaces is a prerequisite.
