Animating
Non-Standard
Symbols
Often there are times when you need symbols with forms and animations
that are not standard in the OSx library.

A control valve symbol animates the bonnet of the valve to red
(manual) or green (automatic) indicating the mode of the associated
PID loop.

A control valve symbol animates the body of the valve to red (closed) or
green (not closed) indicating whether the control valve is opened or not.
To achieve these animations, you can create a single integer and manipulate
it from the associated math of the corresponding PID loop to provide the
status information for OSx. In this case, two tags may be needed for each
PID loop created in APT.
Validation Failure
If the tag installation procedure fails, the problem is often due to an initial
value that falls outside the H_RANGE and L_RANGE values. For a
temporary correction, you can edit the INSTALL.TAG file and either change
the initial value or the high and low ranges. Refer to Appendix A of this
manual for a description of the INSTALL.TAG file.
Unless you make the correction in the APT program and then recompile,
however, the error will continue to occur during installation.
