5.2.1 Slave address
Each slave must have a unique address (from 1 to 247) so that it can be addressed independently
from other nodes.
5.2.2 Baud rate
Select the communication speed for the network. The default value is 9600 baud.
5.2.3 Parity type
You can select the parity type for the network. Modbus RTU specifies the stop bit configuration
shown in table below. You can modify this stop bit configuration manually using parameter
P5.X.3.1.4.
5.2.4 Stop bits
You can select the stop bit amount for the Modbus RTU network.
5.2.5 Communication timeout
Modbus initiates a communication error for a time defined with this parameter. '0' means that no
fault is generated.
5.2.6 Operate mode
Used to select the operate mode of the Modbus RTU protocol (slave / master). 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.
