Modbus TCP Settings
Common Settings
Connection limit (P5.9.2.1.1)
Defines how many clients can access the server simultaneously.
Unit identifier number (P5.9.2.1.2)
The Modbus slave address field usually used on Modbus Serial Line is replaced by a single byte Unit Identifier.
On TCP/IP, the Modbus server is addressed using its IP address; therefore, the Modbus Unit Identifier is not used.
Communication time out number (P5.9.2.1.3)
Modbus initiates a communication error if the Ethernet connection is lost. Communication time-out parameters
define the minimum delay between packages received from the client. The timer is reset and started after each
received package. This parameter can be used if the client is periodically polling the slaves.
Modbus TCP Monitoring Values
These values only display after a connection has been established.
Connection 1
Fieldbus protocol status (P5.9.2.2.1.1)
The Fieldbus Protocol Status provides the status of the protocol.
