Operating Procedure - Mitsubishi Electric MELSEC iQ-R Series User Manual

Operating procedure

The following describes the procedure before starting the I/O data exchange.
When the automatic start is selected
1.
Set the automatic start as the method of starting the IO device data exchange.
Turn off the bit of 'IO device data exchange start method setting area' (Un\G17001 to Un\G17008) corresponding to the IO
device that exchanges the I/O data. (Default: OFF)
2.
Check the status of 'Parameter setting status' (Un\G17118.0).
When it is on, the start of the I/O data exchange can be requested.
3.
Request the start of the I/O data exchange.
Turn on 'Data exchange start request' (Un\G17000.0).
4.
The I/O data exchange with the IO device starts automatically.
■Checking the communication status of the IO device
Check the communication status of the IO device in 'IO device communication status' (Un\G17153 to Un\G17160). When the
bit corresponding to the IO device that exchanges I/O data is on, the data exchange is in progress.
■Checking the error status of the IO device
Check if an error has occurred in the IO device in 'IO device error' (Un\G17161 to U\G17168). When the bit corresponding to
the IO device that exchanges I/O data is on, an error has occurred. Check the error details in 'IO device error details'
(Un\G21858 to Un\G21921) and take actions. ( Page 152 IO device error details)
When the manual start is selected
1.
Set the manual start as the method of starting the IO device data exchange.
Turn on the bit of 'IO device data exchange start method setting area' (Un\G17001 to Un\G17008) corresponding to the IO
device that exchanges the I/O data.
2.
Check the status of 'Parameter setting status' (Un\G17118.0).
When it is on, the start of the I/O data exchange can be requested.
3.
Request the start of the I/O data exchange.
Turn on 'Data exchange start request' (Un\G17000.0).
4.
Set the start request of the I/O data exchange for each IO device.
Turn on the bit of 'IO device data exchange management setting area' (Un\G17009 to Un\G17016) corresponding to the IO
device that exchanges the I/O data.
5.
Set the execution request of the I/O data exchange for each IO device.
Turn on the bit of 'IO device data exchange management execution request' (Un\G17017 to Un\G17024) corresponding to the
IO device that exchanges the I/O data.
6.
When the bit of 'IO device data exchange management execution completion' (Un\G17120 to Un\G17127)
corresponding to the IO device that exchanges the I/O data is on, the start request of the IO device has successfully
been completed.
7.
The I/O data exchange with the specified IO device starts.
■Checking the communication status of the IO device
Check the communication status of the IO device in 'IO device communication status' (Un\G17153 to Un\G17160). When the
bit corresponding to the IO device that exchanges I/O data is on, the data exchange is in progress.
■Checking the error status of the IO device
Check if an error has occurred in the IO device in 'IO device error' (Un\G17161 to U\G17168). When the bit corresponding to
the IO device that exchanges I/O data is on, an error has occurred. Check the error details in 'IO device error details'
(Un\G21858 to Un\G21921) and take actions. ( Page 152 IO device error details)
