Word Bit Description Definition
1
0/0 Run program When this bit changes from 0 to 1, the GML Commander application program
executes from the beginning. If the application program is already running or
paused, the change has no effect. The SLC stop bit described below has
priority over this bit. The application program cannot access this bit.
0/1 Stop program When this bit is set to 1, the application program stops. The application
program cannot access this bit. This bit has priority over the Run and Pause
bits.
0/2 Pause/resume
program When this bit changes from 0 to 1, the GML Commander application program
pauses. When the bit changes from 1 to 0, the program resumes. The
application program cannot access this bit.
0/3 SLC process fault When the SLC sets this bit to 1, the 1394 GMC Turbo system software
generates a global fault. The corresponding global fault code indicates the
SLC process fault. The application program cannot access this bit.
0/4 Reserved N/A
0/5 Reserved N/A
0/6 M0 File update
request If M file manual is enabled, the SLC ladder program can set this bit to 1, which
causes the 1394 GMC Turbo to update the M0 file. The GML Commander
program references this bit as the system variable SLC_M0_Update_Request.
0/7 M1 file update
acknowledge If M file manual is enabled, the SLC ladder program can set this bit to 1, which
causes the SLC ladder program to acknowledge the 1394's request to update
the M1 file. The GML Commander program references this bit as the system
variable SLC_M1_Update_Acknowledge.
