When PLC rack is inserted in PLC manager, slots startwith number 1. If I use Allen-Bradley PLSs, the module numbers start with 0. So all the addressing. Before you can program any PLC system, you have to understand how the addressing is done in that particular PLC. I have included a actual screenshot from RSLogix 5000 below that shows examples of addressing in RSLogix 5000. INSTRUCTION – RSLogix 5000’s Relay Ladder Logic command language is comprised of “instructions”. An XIC (it looks. Note: Discrete I/O is Not Supported by SLC 5/01 and 5/02. There are a few different formats of addressing that C-more supports when connecting to the Allen-Bradley SLC 500 and MicroLogix PLCs. The Expanded I/O format allows the slot and word to be specified, which is more typical when trying to access Analog I/O data. Prerequisites: Before you begin, first insure your PLC-5 has serial port (not all do.) Specifically, the new platform PLC-5/11, 5/20, 5/30, 5/40, 5/60, and 5/80 all have a 25 Pin D-Shell Serial Port. Note that the 9 Pin D Shell on the PLC-5/10, 5/12, 5/15, and 5/25 is not a serial port but instead internally tied to the DH+ terminal block.
