(c) Examples of programs that initialize indicator LED and communication error
information
The following shows examples of a program that reads error codes when
errors described in (1) above occur in an interface on the CH1 side and
initializes the indicator LED and communication error information.
Incorporate the necessary part of the program.
(Input/output signals X/Y00 to X/Y1F of C24)
1) When data is communicated using the MC protocol
Check the error codes and take corrective actions according to Section 15.2.
2) When data is communicated using the predefined protocol
Check the error codes and take corrective actions according to Section 15.2.
3) When data is communicated using the nonprocedural or bidirectional
protocol
Check the error codes and take corrective actions according to Section 15.2.
