Details of master I/O signals

For message communication (X02), (X05), (Y12)
Use 'Message communication completion' (X02), 'Message communication error signal' (X05), 'Message communication
request' (Y12) for message communication.
Execute when 'Master function communication status' (Un\G432) is "OPERATE (C0H)" or "STOP (40H)".
For the message communication, set the parameter for master function.
When the parameter for master function is not set, make the message connection using the message group 1.
• When the command data is set to 'Message communication command' (Un\G272 to Un\G287), and 'Message
communication request' (Y12) is turned on, the message communication starts. (Set the interval of turning on 'Message
communication request' (Y12) to 100ms or longer.)
• When the message communication completes, the processing result is stored in 'Message communication result' (Un\G288
to Un\G303) and 'Message communication completion' (X02) turns on. When completed with an error, 'Message
communication error signal' (X05) turns on.
• When 'Message communication request' (Y12) is turned off, 'Message communication completion' (X02) and 'Message
communication error signal' (X05) turn off.

(1) When completed with an error
(2) Message communication command (MOV/TO instruction)
(3) Message communication data (MOV/TO instruction): Only when transmitting data
(4) Message communication result (MOV/FROM instruction)
(5) Message communication data (MOV/FROM instruction): Only when receiving data
For master function error (X03), (Y13)
'Master function error set signal' (X03) and 'Master function error reset request' (Y13) are used for the notification of an error
while executing the master function and the reset of the error code.
• If an error occurs in the master function, the error information is stored in 'Master function error information' (Un\G433),
'Master function communication error information' (Un\G1152), or 'Other slave communication error information' (Un\G1154
to Un\G1217) and 'Master function error set signal' (X03) turns on. When the error cause is eliminated, 'Master function
error set signal' (X03) turns off. (However, it does not turn off while the I/O communication is stopped.)
• If 'Master function error reset request' (Y13) is turned on after eliminating the error cause, the error code of 'Master function
error information' (Un\G433) is cleared.
