Refresh Settings

The refresh automatically transfers data between the buffer memory areas related to the I/O data exchange of the RJ71PN92
and the devices of the CPU module.
When the auto refresh setting is set, a global label related to the RJ71PN92 is automatically generated. The device set in the
auto refresh setting is assigned to this generated label. When the auto refresh setting is not set, the buffer memory address of
the RJ71PN92 is directly assigned to the global label.

Applicable buffer memory areas

The following table lists the buffer memory areas related to the I/O data exchange of the RJ71PN92.
Buffer memory address
Un\G17000 to Un\G17057
Un\G17118 to Un\G17168
Un\G31000 to Un\G35095
Un\G36000 to Un\G40095
Data cannot be transferred to the following buffer memory areas related to the service interface functions by
using the refresh settings. Use the global label which is automatically generated at the label update of
PROFINET or create a program to access the buffer memory areas.
• 'Service execution request 1, Service execution request 2' (Un\G17057)
• 'Service execution status' (Un\G17144)
• 'Service request area 1' (Un\G50000 to Un\G52087)
• 'Service request area 2' (Un\G52250 to Un\G54337)
• 'Service response area 1' (Un\G57000 to Un\G59087)
• 'Service response area 2' (Un\G59250 to Un\G61337)
