When a NEURO has multiple I/O boards installed, the following numbering convention is used to identify each board.
The physical slot into which a board is installed always represents the I/O identifier prefix.
For example, if an Analog Board is installed in slot 1, its ID prefix will be 1. So inputs it would be 1A1 to 1A8.
If the same board would be moved to slot 2, its input ID would change to 2A1 to 2A8. On this last example, if a Digital Board is installed in vacated slot 1, then the Digital I/O would be 1D1 to 1D8. If a relay board is installed in slot 3, then the relays would be identified as 3R1 to 3R5.
A NEURO with 5 Analog Boards would have 40 inputs identified as: 1A1 to 1A8, 2A1 to 2A8, 3A1 to 3A8 … 5A1 to 5A8.
Note that the numbering convention is different when the NEURO is used in MODBUS mode. See this article for details on the register structure.
In the SNMP MIB, the I/O OID’s all follow a continuous numbering scheme similar to the MODBUS convention.
For the next step, please connect a network (Ethernet) cable between the AXON/NEURO and your computer. The AXON/NEURO should have been previously powered-up as explained in this article.
