Remote Device Test - Mitsubishi Electric MELSEC iQ-R Series User Manual

Remote device test

The output of the remote station can be turned on or off when the CPU module is in STOP state.
Ordinarily, the output of the remote station with the output HOLD/CLEAR setting function cannot be turned on or off. In that
case, use the remote device test function.
When checking the connection between the remote station and the external device by turning the remote output on or off, the
connection can be checked during CPU STOP (without using a program) if the remote device test is used.
For the output HOLD/CLEAR setting function, refer to the following.
 Manual for the remote station used
Before using this function, check the firmware version of the RJ71GN11-T2. ( Page 320 Added and
Enhanced Functions)
Output hold/clear setting during CPU STOP
The following shows the current value of RY when "Output Hold/Clear Setting during CPU STOP" is set to "Clear".
• When the remote device test is disabled ('Remote device forced output request' (SB0016) is off): The current value of RY is
cleared.
• When the remote device test is enabled ('Remote device forced output request' (SB0016) is on): The current value of RY is
output and can be checked.
■Output value in the remote station when the remote device test is enabled
The following table lists outputs in the remote station according to the operating status of the CPU module.

with an offset value.
Setting method
Execute the remote device test according to the following procedure.
1.
Set the RUN/STOP/RESET switch to the STOP position of the CPU module.
2.
Turn off and on the 'Remote device forced output request' (SB0016) to start the remote device test.
3.
Check that the 'Remote device forced output request accept' (SB0086) and 'Remote device forced output status'
(SB0087) are on. (In addition, check that the 'Remote device forced output result' (SW025A) is 0 (no error).)
4.
Check by turning on or off the output of the remote station.
5.
Turn on and off the 'Remote device forced output request' (SB0016) to end the remote device test.
