Communication Loss

Description

Communication loss function:

  • Detects the loss of communication between the LTMT main unit and the PLC or DCS connected through the communication network, once communication has been established.

  • Generates an alarm or a trip action according to the function setting.

When Trip in Remote Mode only setting is enabled, the LTMT main unit sends the trip command only when the motor is running in Remote mode. If the motor is running in Local mode, the LTMT main unit sends only the alarm signal.
