In the following example, when X1 is on and the module busy relay SP124 (see special relays)
is not on, the RX instruction will access an ECOM or DCM operating as a master in slot 2.
Ten consecutive bytes of data (V2000 – V2004) will be read from a CPU at station address 5
and copied into V-memory locations V2300–V2304 in the CPU with the master DCM or
ECOM.
