[code]A I0.0 L S5T#4S // WAITING TIME SD T0 NOP 0 A T0 = M0.0 //COPY OF I0.0 ACCEPTED WITH DELAY[/code] Regards

Hello hextalker you can only do it in HWconfig if the DI card supports it (e.g. interrupt capable ET200M DI, High feature ET200S DI etc.), so the question is: What type of DI card (part number) do you have?

You can read the following in the CIR manual, CIR manual Hardware Requirements Please refer to the About text in the "Hardware Catalog" window for information on which ET 200M modules (signal modules and function modules) / ET 200iSP you can reconfigure in CPU RUN mode. A 20msec delay may and may not solve your problem. If it's still not sufficient then you will have to go with ON delay timers as suggested by hdhosseini. if you have STEP7 V5.5 then thiswill be your CIR manual. Best regards, H-H
