Rung 2:4
If both the ready bit and the sequencer done bit are high (the module has
received a valid parameter block and has loaded all the motion blocks), rung 2:4
moves the source address of the command block into the BTW’s control block
causing the programmable controller to send a command block when rung 2:5 is
executed.
Rung 2:5
Rung 2:5 writes the block selected by rung 2:1, 2:3 or 2:4 to the module.
