Local Control
Local Control can be used when the system is inspected or calibrated by crew. When Local Control is enabled, the WMS
can only be started and stopped from the LCP. Local Control can be enabled using the Modbus interface or using the LCP
Local Control can only be disabled using the LCP. Local Control ensures that the sensor is not started unintentionally by
another system thus allowing crew to perform inspection and maintenance operation on the system.
When Local Control is disabled, the WMS must be started and stopped using command through the Modbus.
When Local Control is enabled, readings from the sensor can still be obtained over Modbus. The only difference is that
the system can’t be started over Modbus.
