Modbus/TCP 18
Timeout
When a Modbus/TCP timeout value is configured, see the “Bus Configuration Parameters” chapter, a
network error will be generated to the drive if the time between two Modbus messages exceeds the configured
value.
Note: If the Modbus/TCP protocol is used for controlling the drive, a timeout value shall be configured so that the
drive trips if the connection with the master fails.
