UDT Mapping to Discrete I/O

[RBPLC]

Is there a way to directly map a UDT field to a physical I/O? For example, if I have the UDT Tank0.HighLimSwitch, can this be directly mapped to say X0, or would I have to use something like the COPY command to write the X0 value to the UDT field?

Use the MAPIO instruction.

You could also use COPY (it works for any data type, not just bits, which is what MAPIO only supports).

Both are table-based instructions, so you can map/copy multiple entries in a single instruction.
