Check_box Write values

[PxPlus]

When issuing a WRITE to a Check_box (or Tristate_box) the value written will be interpreted are as follows:

- If the value is one of the translation table values, it's position in the table defines the state (First=off, Second=on, Third=Other for Tristate)
- If the value is "0", "N" or NULL ("") set off
- If the value is "1" set on
- If the value is "2" set to other state (Tristate only)
- Any other value sets the check box on
