2.1 General

I/O system configuration
You can fit up to 13 modules of the type BIM, up to 6 BOM or IOM in
any combination, and up to 6 modules of type MIM in one REC 561, but
totally maximum 13 modules. In REL 531, you can fit up to 5 modules
and no MIM.
Each module can be placed in any CAN-I/O slot in the product. To add,
remove, or move modules in the product, reconfigure the product from
either the graphical configuration tool or for REL 531, from the built-in
MMI.
Users refer to the CAN-I/O slots by the physical slot numbers of the
CAN-I/O slots, which also appear in the product drawings.
If the user-entered configuration does not match the actual configuration
in the terminal, an error output is activated on the function block, which
can be treated as an event or alarm.
The BIM, BOM, and IOM share the same communication addresses for
parameters and configuration. So they must share I/O module 1-13
(IOxx), which are the same function block. A user-configurable function
selector per I/O module function block determines which type of module
it is.
All names for inputs and outputs are inputs on the function blocks and are
set from the graphical tool for REC 561. You can also configure the first 5
I/O modules from the built-in MMI or the SMS, but only for REL 531.
