When using the [Tag Address Translation](docId\:ZW6smUCz3PRv3HZW4uWYL) functionality, users can provide a common string expression of a tag address which are typically use by the tools used to program the PLC such as Siemens TIA Portal or PCWin.

Currently the Tool supports Tag Address Translation for these drivers:

- Siemens S7
- All ModBus Drivers
- Toyopuc Ethernet

Because Excel doesn't resepct leading "0" for a number value, OutPut Coils need to include a leading "'" (Apostrophe) when using the Decimal Format.

Example:
Will not work: 065536
Will work: '065536
