Technical support / Re:VFD to PLC

I know and I understand that.
I am learning using your software before I buy the PLC. This one was handed to me for the time being, becuase they had it in storage.

Hey,

I checked, my PLC has two RS232 ports, and the VFD has one RS485.

Thanks,

Sara.

Hi.

Thanks for the quick reply.
I am using a DELTA VFD-M drive (variable frequency drive) and a DL05 PLC.
the PLC has two ports and the VFD has one.
So thats all I gotta do? RS485?

Thanks,

Sara.

Technical support / sequencer timing
« on: January 29, 2009, 12:09:34 PM »
Hi.

I am very new to PLCs
I am trying to use a sequencer to be able to start and stop a motor. i understand that the sequencer needs to go from on to off to increment. i tried using 1.0 s clock, which runs each sequence for 1.0 second. My problem is that i want to run sequence 1 for 30 sec seq 2 for 5 sec and seq 3 for 30 sec..and so on. does anyone have any idea on how to do it?

I would really appreciate any help.

Thanks :)

sara.
