Details of slave I/O signals

For slave function error (X08), (Y18)
'Slave function error set signal' (X08) and 'Slave function error reset request' (Y18) are used for the notification of an error
while executing the slave function and the reset of the error code.
• When an error occurs in the slave function, the error information is stored in 'Slave function error information' (Un\G1537)
or 'Slave function communication error information' (Un\G1153) and 'Slave function error set signal' (X08) turns on. When
the error cause is eliminated, 'Slave function error set signal' (X08) turns off. (However, it does not turn off while the I/O
communication is stopped.)
• If 'Slave function error reset request' (Y18) is turned on after eliminating the error cause, the error code of 'Slave function
error information' (Un\G1537) is cleared.
