ADS Services
Local process image task 1 port 801
Data can be read from and written to the local process image. If it is necessary for outputs to be written, it is
important to ensure that they are not used by the local PLC, because the local controller will overwrite these values.
The data is not associated with a watchdog, and therefore must not be used for outputs that would have to be
switched off in the event of a fault.
