Status Monitoring
The Status Monitoring function provides status information of field devices when the MGate is being used as
a Modbus client. If a Modbus device fails or a cable comes loose, the gateway won’t be able to receive up-
to-date data from the Modbus device. The out-of-date data will be stored in the gateway’s memory and will
be retrieved by the client (e.g., PLC), which is not aware that the slave device is not providing up-to-date
data. To handle this situation, the MGate provides a warning mechanism to report the list of slave devices
that are still “alive” through the Status Monitoring function.
The MGate will create a status tag when a Modbus device is created. This shows if the Modbus device
connection is valid or invalid. However, these tags cannot be added to the EtherNet/IP mapping of a client
(e.g., PLC) to get the alive status of the Modbus devices.
The highest significant bit shows the status. 1 is invalid, 0 is valid.
