PTOX Output (OUT)
The PTOX OUT (Output) variable defines the output (O0:0/2, O0:0/3 or
or O0:0/4) that the PTO instruction controls. This variable is set within the
function file folder when the control program is written and cannot be set
by the user program.
• When OUT = 2, PTO pulses output 2 (O0:0.0/2) of the embedded
outputs.
• When OUT = 3, PTO pulses output 3 (O0:0.0/3) of the embedded
outputs
• When OUT = 4, PTO pulses output 4 (O0:0.0/4) of the embedded
outputs.
