5.2 EIP Configuration
5.2.1 EIP Class 3 Server Connection
The EIP Class 3 Server Connection is used when the gateway is acting as a
server (slave) device responding to message instructions initiated from a Client
(Master) device such as an HMI, DCS, or PLC5.
Configuring EIP Class 3 Server Connections in PCB
The PLX3x Server connection file size is user selectable for 100 or 1000
integers. If a value of 100 is selected valid registers will be from N10:0 to N10:99.
If a value of 1000 is selected valid registers will be from N10:0 to N10:999.
