PAC Control: Changing type of I/O unit for a subroutine parameter causes parameter to disappear and compile errors
- PAC Control Basic
- PAC Control Professional
R10.0 to R10.5a
Resolved In Version:
If a parameter of a subroutine has an I/O unit as the type (for example, SNAP-PAC-R1), and then you change the I/O unit to another type (for example, GRV-EPIC-PR1), you may observe the following behaviors:
- The parameter disappears from the strategy tree.
- When you compile the subroutine, there will be errors.
This issue occurs when you are editing a subroutine created before a newer I/O unit was available (for example, a subroutine created before GRV-EPIC-PR1 was released).
Try one of the following:
- Rewrite the subroutine in the latest version of PAC Control
- Replace the old parameter with a new parameter:
- Create a new parameter with the desired type of I/O unit.
- Change all references of the old parameter to refer to the new parameter
- Remove the old parameter.
- Change the position of the new parameter to be that of the old parameter.
