Supported ADP Message Types
The 1756-CLX/C module supports the following communication features referenced in
the ADP specification:
Configuration Requirements
Before you can use your 1756-CLX/C module, you must configure its IP address,
gateway, and subnet mask by specifying parameters NX00 through NX02 on the
Logix5000 controller. Refer to Appendices D and E of this manual for definitions of these
parameters.
IP Address
The IP address identifies each node on the TCP/IP network (or system of connected
networks). Each TCP/IP node on a network must have a unique IP address.
The IP address is 32 bits long and is composed of a net ID, host ID, and/or a multicast ID.
Each network can be a Class A, B, C, or D format. The class of the network determines
how an IP address is formatted.
