Users can refer to the EIP Builder data exchange page (see below) to find out the number of CIP and TCP
connections. The method for calculating the number of CIP connection is also listed below. .
Series Model
Method to Calculate CIP Connection
AH
AHRTU-ETHN-5A
Limited to AHCPU and third-party host
1) RTU + DIO uses 1 connection
2) Each AIO or NIO module uses 1 connection
Each data exchange group uses 1 connection
AHCPU5x1-EN
