5.4.2 Modbus TCP settings
5.4.2.1
Common settings
P5.8.2.1.1 CONNECTION LIMIT
Defines how many clients can access the server simultaneously.
P5.8.2.1.2 U
NIT IDENTIFIER NUMBER
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 useless.
P5.8.2.1.3 C
OMMUNICATION TIME-OUT
Modbus board initiates a communication error if the Ethernet connection is lost. Communica-
tion time-out parameters define the minimum delay between packages received from the cli-
ent. The timer is reset and started after each received package. This parameter can be used if
the client is periodically polling the slaves.
