11. Node Monitor

11.1 General

The Node Monitor can provide valuable information when setting up the communication with the sub-
network, by allowing individual commands to be issued manually, and monitoring the response (if ap-
plicable). It also provides an overview of the memory used by a particular node.
Note: The node monitor has a negative influence on the overall performance of the gateway, i.e. it
should be used only when necessary.
The Node Monitor behaves somewhat differently in the three protocol modes:
• Master Mode and DF1 Master Mode
The selected Command (Query Transaction) or Service is sent to the subnetwork. The response
to the Query can be monitored in the Response Section.
• Generic Data Mode
The selected command (Transaction Produce) is sent to the subnetwork. It is not possible to
monitor any responses etc. generated by other nodes.
