High−level Instructions
3 − 388
Precautions during programming
Multiple F147 (PR) instructions cannot be executed at the same time. The program should be set up so that
the printout flag (R9033) is used during execution of F147 (PR) instruction to inhibit simultaneous execution.
The ASCII code conversion instruction [F95 (ASC)] can be used to convert character constants (M) to ASCII
codes.
Character constants (M) can be input only with programming tool software.
A transistor−type output unit/board is necessary.
When this instruction is executed, of the WY area specified by D, zero <off> is set for Y_9 to Y_F.
Flag conditions
・Error flag (R9007): Turns on and stays on when:
・Error flag (R9008): Turns on for an instant when:
− The ending area for storing ASCII codes exceeds the limit.
− The trigger of another F147 (PR) instruction turns on while one F147 (PR)
instruction is being executed.
・Printout flag (R9033): Turns on and stays on while a F147 (PR) instruction is being executed.
