I have a cpu315-2 dp set up as the master and an Omron Prt21 card set up as a slave and i was wondering if there is a way to transmit a data block across rather than just transmitting outputs from the cpu315.
Also I am having difficulty addressing PIW words in Siemens. The system fault light turns on whenever I address the PIW word (the Peripheral input is not connected at the moment is that why it faults).
