Block 9910: CROB Data received on DNPNET Port

Block identification code 9910 is used to send CROB messages received on the DNPNET

server port to the processor. For pulse or trip/close operations with a fast duration, this block

can be used to pass the information into the ControlLogix processor. Additional ladder code

can be written by the user to perform the operation in locally in ladder code, making sure

that a CROB message from an attached client is not missed due to database paging being

too slow for the control operation.
