| Hi,
I have a problem trying to communicate with a m580 from schneider. I've already used Process simulator many times with m340 with reasonable communication time.
The project is about 400 items in communication and it takes about 40 seconds to show impact on forced bits in the CPU.
I've tried to use a previous project that was made for m340 and which worked perfectly (2-3s communication time), applied to the m580 it went up to 20s communication time.
I guess the problem comes from a setting in the CPU but I can't find it.
Does anyone ever encountered this issue and have an idea?
Thanks
Greg.

| Hi
It appears it was only due to a setting in schneider's Control Expert that said the main task was periodic and was done once every 100ms.
Now with a new setting of 10ms, communication time dropped to 4.2s.
That's good enough for us.
Thanks.
Greg
