6.6.3.4 System Variables
Since the operating devices do not have diagnostic LEDs, you need to
use system variables to indicate specific DeviceNet statuses. You can
create these system variables within any mask as output variables. To
do so, select the representation type Selection Text and link the vari-
able with a text list containing a text string for each status.
ComBaudrateA
This system variable can be used to indicate the statuses of the
module/network LED.
ComHandshakeA
This system variable allows you to indicate whether the data memory
has been initialized by the master.
