Description
The high-speed digital outputs of the digital on-board
I/O module support technology functions such as fast
counting, measuring, position detection and pulse
generators (PWM, PTO and frequency output). Due
to the supported technology functions, the compact
CPUs are suitable for controlling pumps, fans, mixers,
conveyor belts, lifting platforms, gate control systems,
building management systems, synchronized axes,
etc.
You have the option of reassigning parameters for the
digital on-board I/O module in RUN (for example,
behavior during CPU STOP, without affecting the
other channels).
Value status = 1 ("Good") indicates that the process
value specified by the user program is correctly out-
put at the terminal.
Value status = 0 ("Bad") indicates that the process
value output at the hardware output is incorrect or the
channel is used for technology functions.
