Programming

Scanned events may also be used with a timer to perform an action on the periodic time basis.

The program statements contained in the action portion of the scanned event can be any legal program statement except

the following statements: Subroutine calls (GOSUB), DO/WHILE, WHILE, WAIT, GOTO and also motion commands:

MOVED,MOVEP, MDV, STOP, MOTION SUSPEND/RESUME.

EVENT <name> INPUT <inputname> RISE

This scanned event statement is used to execute a block of code each time a speciﬁed input <inputname> changes its

state from low to high.

EVENT <name> INPUT <inputname> FALL

This scanned event statement is used to execute a block of code each time a speciﬁed input <inputname> changes its

state from high to low.

EVENT <name> TIME <timeout>

This scanned event statement is used to execute a block of code with a repetition rate speciﬁed by the <timeout>

argument. The range for “timeout” is 0 - 50,000ms (milliseconds). Specifying a timeout period of 0 ms will result in the

event running every event cycle (256ms).

EVENT <name> expression

This scanned event statement is used to execute a block of code when the expression evaluates as true.

EVENT <name> ON/OFF

This statement is used to enable/disable a scanned event. Statement can be used within event’s block of code.

Scanned Event Statements Summary

Table 15 contains a summary of instructions that relate to scanned events. Refer to Section 3 “Language Reference”
