WI Series lets you add mappings to define how the system shares information. Conceptually
a mapping takes the value of an input and shares it with another module, usually by setting
the state of one of the module outputs. The mapping display shows all inputs (including
physical inputs and internal inputs) for the selected module.
WI-I/O 9-L-T transmits messages only; it cannot receive messages and has no
communication failure contingency.
WI Series lets you send multiple input values in a single message to help reduce the number
of transmissions.
You can also:
Invert inputs – if you invert an input, the transmitted message sends the inverse value
of the actual input; and
Reverse analog inputs – the inverse of an analog input reverses the magnitude of
the value (e.g. 4mA becomes 20mA).
Note
Do NOT invert pulsed inputs.
WI Series uses arrows to indicate the communication direction:

1-way communication
2-way communication (i.e. re-transmits
message if no acknowledgement received).
