12.2 Response of Digital Outputs to
Timeout
In case of a timeout in system bus communication, each of the outputs can be set to
an error status to be defined by the user.
The user can specify whether an output should maintain its state or whether it is to
be set or reset in case of an error..
The error status of outputs can be defined using register array element 50 "Outputs
- Error Mode", and 51 "Outputs - Error Status".

Re-initialization of JX2-IO16 following timeout
Once a timeout error has occurred, the module is in STOP state. Thus, without re-
initialization it can no longer be addressed.
There are two ways to re-initialize the module:
• Initialization # 1:
The module is re-initialized from the controller using a command or a special
function.
• Initialization # 2:
The module is re-initialized by switching the controller and the module off and,
then, on again.

Note!
The controller saves the last output state of the JX2-IO16 module before the
timeout has occurred. If the output state has changed as a result of an error status
on the JX2-IO16 module, the output state, which has been saved by the controller
for the JX2-IO16, is no longer applicable.
