Note: DiscreteI/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 PLC.
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. The Non-Expanded I/O format only allows the slot to be specified and is more typical when trying to access Discrete I/O. The Non I/O Addressing format should be used for all other memory types.
| Memory Type | File Number | Slot Number | Word Number | Bit Number | Description | Flag | Read/Write Type | Data Type |
