Details of I/O signal common in the master function and the slave
function
Watchdog timer error (X00)
This signal turns on when a hardware failure occurs on the RJ71DN91.
• Off: Module normal
• On: Module failure
'Watchdog timer error' (X00)
'Module READY' (X0F)
I/O communicating (X01), I/O communication request (Y11)
Use this signal when starting the I/O communication with each slave node.
Execute while 'Module READY' (X0F) is on.
■When starting the I/O communication by 'I/O communication request' (Y11)
• When 'I/O communication request' (Y11) is turned on, the parameter is checked.
• When the parameter check normally completes, the I/O communication with each slave node starts and 'I/O
communicating' (X01) turns on.
• When the parameter check abnormally completes, the ERR LED turns on and 'Master function error set signal' (X03) or
'Slave function error set signal' (X08) turns on. 'I/O communicating' (X01) does not turn on at this time. For details on
'Master function error set signal' (X03) and 'Slave function error set signal' (X08), refer to the following.

Page 69 For slave function error (X08), (Y18)
• When 'I/O communication request' (Y11) is turned off, the I/O communication with each slave node stops and 'I/O
communicating' (X01) turns off.
When parameter check normally completes
