... Therefore V1206 is equivalent to Base + 6. Using the table above, Base + 6 is mapped to DRO 1506. So writing to DRO 1506 writes that word (16 bits) to the PLCs memory location V1206. You can write to it in VB using SetUserDRO(1506,Value) where Value is the number you want to write. ... After your PLC is programmed with the communication check (as described above), you are ready to read and write to memory inside your PLC. To simplify your job of accessing external I/O, our control maps user LEDs and pin numbers of port 0 to 4 different registers. This allows for a maximum of 64 inputs and 64 outputs. If you write those registers to ... The MachMotion plugin writes the data from a PLC to user DROs. Inputs to Mach3 are mapped to DRO numbers 1600 – 1699. Outputs from Mach3 are mapped to DRO numbers 1500‐1599. DROs 1500‐1504 and 1600‐1604 are reserved for PLC I/O and the communication check. See the tables below. ...
