Allen-Bradley Micro800 Serial Addressing

Topic: CM355

The C-more panel communicates to the AB Micro800 PLC through symbolic Addressing on EtherNet/IP.

Communications are limited to Global Variables (No Program Local Variables or Function Block Local Variables) of Atomic Data Types and Arrays of Atomic Data Types up to two dimensions.

The Atomic Data Types that can be accessed are shown in the chart below:
