The COMMREQ Function Block is the ladder instruction that triggers the execution of the Channel command. In the COMMREQ Function Block, you specify the rack and slot location of the Ethernet Interface, a task value, and the address of a location in memory that contains the Command Block. There is also a fault output on the COMMREQ Function Block that indicates certain programming errors. 

The address in CPU memory of the Command Block is specified by the IN input of the COMMREQ Function Block. This address can be any valid address within a word-oriented area of memory (%R, %AI, or %AQ for the Series 90-30 Ethernet Interface and the Series 90-30 CPU364) (%R, %AI, %AQ, %P, or %L for the Series 90-70 Ethernet Interface (Type 2)). The Command Block is set up using an appropriate programming instruction (the BLOCK MOVE or DATA_INIT (Series 90-70 PLC only) Function Blocks are recommended)
