C Determining the Cycle Time
The program cycle is the complete execution of the
program, primarily the reading in of the inputs, the
processing of the program and the subsequent reading out
of the outputs. The cycle time is the time required to
execute a program once in full.
The time required for a program cycle can be determined
using a short test program. The test program is created in
IDEC SmartRelay and produces a value during processing
in parameterization mode from which the current cycle time
can be calculated.
Test program
1. Create the test program by linking an output or marker
to a threshold switch and by switching a clock pulse
generator at its input, which is switched on by a hi
signal.
2. Parameterize the two blocks as shown below. A clock
pulse is generated in each program cycle based on the
cycle time of 0 seconds. The time interval of the
threshold switch is set to 2 seconds.
