GT21 Slider value at power-up

3 posts in this topic

I am using a GT21 with an FX3G PLC. I have a slider that is set to 0-100 linked to D5 in the PLC.

When the machine is powered on I need it to recall the previous setting of the slider. At the moment the slider returns to zero, and sends the value to the PLC.

I can't find any mention in any documentation about preserving settings if power is removed.

You''ll need to use a retentive D register.  D128 to D132 from memory.

 

D128 to D1099 from the manual
