(3) How to check the execution status
The execution status of registered executional conditioned device test can be checked in three different ways:
 • By the flash of the MODE LED in green
 • By the on status of the first bit of SD840 (Debug function usage)
 • By the display on the screen for checking the registration status in GX Developer 
(  (4)(d) in this section)
● The MODE LED also flashes in green when the external input/output forced on/off function is used.
To check the execution status using the MODE LED, check the status of the external input/output forced on/off function 
as well. (  Section 6.11.3)
● When using SD840 to check the execution status, remind that SD840 is used to check the status of the external input/
output forced on/off function as well.
