PPCL Reference for PTECs
PPCL Rules for PTECs
● 80 character limit per line. This limit includes tabs, spaces, and line numbers.
● Illegal characters include: ^ ~ # ; < > \ |
On import and when reading a PPCL program from a file or device, the following
conversions are done:
– white space (tabs, line breaks, multiple spaces) becomes a single space
– ^ ~ # ; \ | become a single space
– > becomes .GT.
– < becomes .LT.
● Range of line numbers is 1 to 32767.
● 200 line limit per program. This limit includes comment lines.
● Duplicate line numbers are not allowed in a single PPCL program.
● Line numbers must be in sequential ascending order.
● Empty program lines are eliminated when the program is saved to the PTEC.
When the program is refreshed, empty program lines no longer display.
● For PTEC devices, only the single "PPCL.PGM" program name is available. The
program name cannot be edited.
● Object (point) names in PTEC program lines have validation rules:
– Valid name length: 1 to 12 characters
– Valid characters include: A-Z 0-9 space . ?
– Reserved words are not allowed. See the
Reserved Words section for a list of
reserved words.
– Validation of keywords: see the
PTEC PPCL Keywords section for a list of
PTEC PPCL keywords. In addition:
Only 2 SECNDS timers are allowed (SECNDS and SECND1)
Only 4 $LOC points are supported ($LOC1 through $LOC4)
NOTE: The SECNDS and LOCn objects only exist in the PTEC program. They
will not show up in the Device/Points List and cannot be dragged into the
program. They are not displayed in the Referenced Points List.
● Lines and sections of PPCL code can be reused (copied/cut and pasted).
Priority
● For PTEC devices the command priority is 15, and cannot be changed.
● If a field panel must command a PTEC point, the priority of the PPCL program
must be set to 15 or higher.
