Tab: Modbus TCP Master – General

This tab contains the basic settings for network communication.

Modbus TCP

Response timeout (ms)

Time interval (in milliseconds) for the master to wait for the response from a slave node. If the nodes do not respond within this time span, then an error is issued for the implicit slave function block. The value specified for the time span is also the default value for each node. For each node, you can still set a specific value within its Modbus TCP slave configuration.

Socket timeout (ms)

Maximum time (in milliseconds) to wait for incoming TCP/IP packages The bus cycle task can be blocked during this time. (Example: When a Modbus TCP slave is disconnected)
