IOM Number
Jumper 1 to jumper 6 are used to define IOM number. This is a Binary Coded Decimal,
highest bit is jumper 6 and lowest bit is jumper 1. ON is defined as 1, OFF is defined as
0.
IOM number range must be between 1 to 40 and IOM number should be unique on its
I/O link.
For example, if user wants to set IOM number as 9, then user needs to set jumper 1 to
jumper 6 as “ON-OFF-OFF-ON-OFF-OFF” which means 001001=9 Decimal.
ATTENTION
IO modules connected to the wrong I/O Link does not communicate.
The IOM Number parameter (IOMNUM) specifies the address of the
module on the I/O Link and must match the I/O Link address jumper on
the IOTA.
When changing address, you must ensure that:
a) The IOM is disconnected from the Link,
b) Power cycled after the address change, then
c) The IOM may be re-connected back to the Link.
