588 Status Variables
Program Status
Program_status is an integer value representing the current state of the
application program in the motion controller. When used in an expression
in a GML Commander diagram, the Program_status variable always has
values of 1 indicating that the application program is running.
Ordinarily, you will use the Show Program Status block in the Online
Toolbar’s Select Direct Command window to check the Program_status
variable, rather than use this variable directly in an expression.
In the Tag Explorer select General System Variables, then select
Program_status in the Tag Window.
RIO Status
RIO_status is an integer value representing the present status of Remote I/
O communications. The color of the diagnostic LED, for the appropriate
channel on the front panel of the RIO option, also indicates RIO status.
In the Tag Explorer select General System Variables, then select
RIO_status in the Tag Window.
CNET Status
CNET_status is an integer value representing the present status of CNET
communications, as shown below.
