Operands
An operand can be any of the following:
•
a signed 32 bit decimal number. e.g. 100 or 1 or 0 etc.
•
a hexadecimal number. e.g. 0xABF.
•
a date stamp in the format MM/DD/YYYY e.g 02/10/2010
•
a time stamp in the format HH:MM:SS e.g. 20:25:00
•
a day of week identifier enclosed in single quotes e.g. 'sun'. Day of week
identifiers are 'sun' 'mon' 'tue' 'wed' 'thu' 'fri' 'sat'
•
an I/O identifier that is a place holder for the real I/O value that the PLC
engine will get at runtime. Valid I/O identifiers are explained in next section.

non-zero. If true then program jumps to label specified in
operand b.
Same as BNZ but tests for zero value.
Same as the branch instruction but calls a subroutine
instead of branching. See section on program address stack.
Same as above but tests for zero result.
Calls subroutine with label a. See section on program
address stack.
Branches to program address specified by label a.
Delay instruction, delay specified in 1/1000 seconds. This
delay is blocking delay, so that next PLC instruction will
not execute until delay is over.
A no operation instruction.
A return from subroutine instruction.
