PTO.0.ErrorCode
PTO PTO.0.ErrorCode shows the error code.
PWM - Pulse Width
Modulation
The X8 Series PLC High-Speed Output (PTO and PWM) function supports
up to 100KHz, and is applied to simple motion contr
o
l and high-speed pulse
output.
The PWM function can only be used with the controller's embedded I/O. It
cannot be used with expansion I/O modules.
The PWM instruction should only be used with X8 Series PLC. Relay outputs
are not capable of performing very high-speed operations.
Instruction Type: output
PWM Function
The PWM function allows a field device to be controlled by a PWM wave
form. The PWM profile has two primary components:
• Frequency to be generated
• Duty Cycle interval
PWM Data Table
The PWM instruction, along with the HSC and PTO functions, are different
than all other controller instructions. Their operation is performed by custom
circuitry that runs in parallel with the main system processor. This is necessary
because of the high performance requirements of these instructions.
A typical operating sequence of a PWM instruction is as follows:
1.
The rung that a PWM instruction is on is solved true (the PWM is
started).
2.
PWM function execution (Frequency is generated)
