Determining the cycle time
322 IDEC SmartRelay Manual 
Test program
1. Create the test program by linking an output to a
frequency trigger and connecting the trigger input with an
inverted marker.

2. Configure the frequency trigger as shown below. A pulse
is generated in each program cycle due to the inverted
marker. The trigger interval is set to 2 seconds.

Off=0000 B1 2
G_T=02:00s

3. Now start the circuit program and switch IDEC
SmartRelay to parameter assignment mode. In this
mode, view the trigger parameters.
