Program Execution Flag
Use the four flags listed below to determine the operating status of a task in
Automatic Mode. When the program is executed from the Teaching Box, the
flags will change just as they do in Automatic Mode. These flags are all turned
OFF when the mode is switched from Automatic to Manual Mode.
• Program Execution Flag
• Program Execution Completed Flag
• Optional Input Standby Flag
• M Code Reset Standby Flag
The Automatic Mode Flag won't be turned ON during system initialization,
even if an Automatic Mode Command is received from the CPU Unit. The flag
will be turned ON when initialization has been completed and the Unit is able
to received commands in Automatic Mode. Initialization takes about 700 ms.
