If you wish to change the security key, simply enter a new key in the configuration program, and
download the new configuration to all modules in the system.
4.3.8 Using WI-I/O-EX-1-S-x Modules
WI-I/O-EX-1-S-x modules can be used by themselves, as “line telemetry” or “wired I/O”, or they can
be used as I/O expansion for WI-I/O 9-x modules. As the WI-I/O-EX-1-S-x modules are connected by
RS485, the WI-I/O-EX-1-S-x modules can be separated from the WI-I/O 9 modules by some distance.
There can be up to 32 addresses on the one RS485 multi-drop link. Note that each –3 and –4 module
takes up 2 addresses. For example, you could have up to 32 modules sharing a multi-drop link if they
are all –1 or -2 modules - if they are all –3 or –4, then you could only have 16 modules on the link.
WI-I/O-EX-1-S-x modules are configured with unit addresses in the range 96 – 127.
Example 1 - Mapping to another WI-I/O-EX-1-S-x module on the same link.
The I/O mapping is done in the same way as for WI-I/O 9-x modules.
