Operator Description Returns
emcy(n)
Issues an emergency message from a user program,
where n is error code (32-bit long integer) defined by a
user. Nothing
PrgErr(N)
Returns the last program error of machine N, where N is
a value between -1 and 2. This operator can be used in an
AUTO_PERR routine to query about the recent failure. If
N = -1, the
SimplIQ drive returns the last error code of the
machine from which this function was called. Note that it
makes no sense to call PrgErr(-1) from the interpreter.
Integer
tick
Reads the system time in internal units. This function
uses an internal timer unrelated to the system
microsecond counter (refer to the TM command section
in the
SimplIQ Command Reference Manual). As such, the
TM command timer can be modified by CAN SYNC And
Time Stamp, while the tick function timer is not affected
by any external event.
This function is used to implement the wait statement
(
5.7.5 ). The tick(x) argument is the time difference used
in the wait statement. The valid range of the argument is
[0…32,000] milliseconds, a limitation based on the
implementation of the tock function (following). An
argument greater than 32,000 will abort the tick function
with an OUT_OF_RANGE error code. To read the system
time in internal units, set the argument to 0.
Integer
tock
Returns the time difference.
If internal = tick(x), tock (internal) will return the time in
milliseconds once internal = tick(x) has been sampled.
The tock function operates in a manner similar to tdif,
but it uses an internal timer, unrelated to the system
microsecond counter.
Note:
For a time difference greater than 32 seconds, the
function tock(internal) may return an erroneous result. Integer
The built-in function call may be a part of a single expression.
Examples:
sin(3.14/3)
AC=abs(DC)
SP=SP+sin(3.14/2)
