Details of buffer memory addresses

The following describes the buffer memory addresses of the RJ71PN92.
Current error area
■Current error area (Un\G140)
An error code is stored.
Data exchange start request
■Data exchange start request (Un\G17000)
Set to start or stop the I/O data exchange of the RJ71PN92.
Address
Un\G17000
For the I/O data exchange of the IO device where I/O data exchange manual start is set in 'IO device data exchange start
method setting area' (Un\G17001 to Un\G17008), it is controlled with 'IO device data exchange management setting area'
(Un\G17009 to Un\G17016) and 'IO device data exchange management execution request' (Un\G17017 to Un\G17024).
IO device data exchange start method setting area
■IO device data exchange start method setting area (Un\G17001 to Un\G17008)
Set a method of starting the I/O data exchange of each IO device.
Set this area before turning on 'Data exchange start request' (Un\G17000.0).
• 0: I/O data exchange automatic start
The I/O data exchange between the RJ71PN92 and each IO device is automatically started.
• 1: I/O data exchange manual start
The I/O data exchange between the RJ71PN92 and each IO device is manually started.
By setting 'IO device data exchange management setting area' (Un\G17009 to Un\G17016) and 'IO device data exchange
management execution request' (Un\G17017 to Un\G17024) after turning on 'Data exchange start request' (Un\G17000.0),
the start/stop of the I/O data exchange with each IO device is controlled.

Description
0: RJ71PN92 I/O data exchange stop
The I/O data exchange between the RJ71PN92 and all IO devices is stopped
regardless of the setting of 'IO device data exchange start method setting
area' (Un\G17001 to Un\G17008).
1: RJ71PN92 I/O data exchange start
By setting 1 in this area, the IO device where I/O data exchange automatic
start is set in 'IO device data exchange start method setting area' (Un\G17001
to Un\G17008) starts the I/O data exchange.
