5.1.2 Enabling Modbus protocol
Modbus TCP/UDP is always enabled in VACON
®
100 family devices. You need to parametrize the
network settings (IP address etc) before using it. See Chapter 5.3.1.
When using Modbus RTU, you need to enable the protocol. After enabling it, protocol settings will
appear under panel tree P5.8.3.
5.2 Modbus RTU parameters and monitoring values (M5.8.3)
* This feature is not supported in VACON
®
100 HVAC. The default application in the VACON
®
100
family AC drives supports only Slave mode. A special application is required for Master functionality.
