WI Series lets you set the unit address used by the system when sending messages to a
module.
A valid unit address for the WI-I/O 9-L module is between 1 and 95.
Note
You cannot use a unit address of 0.
A network can have up to 95 addresses communicating via radio (i.e. unit addresses 1 to 95).
Other I/O-series modules support up to 31 serial modules communicating via RS-485. The
upper unit addresses are reserved for identifying these serial modules (i.e. unit addresses 96
to 127). The WI-I/O 9-L-T can send messages to the RS-485 connected serial modules.
You can map any individual input signal in the network to one or more outputs anywhere in
the system.
The unit address determines the method of communication to a module:
Modules with a unit address between 96 and 127
- communicate by RS-485 only.
Other units with a unit address below 95
- can communicate by radio or RS-485.
The unit determines the communication method based on the unit address of the
destination module. For example, Unit 31 can talk to Unit 97 by RS-485 only, but will
talk to unit 59 by radio only.
Note
WI-I/O 9 and WI-I/O-EX units can only communicate via serial communication and must
always have a unit address between 96 and 127.
WI-I/O 9-L units can only communicate via radio and must always have a unit address
between 1 and 95.
