Question: Can I put as many profinet drives as I want onto my profinet ring and if so how.
I have a project where I will be controlling a large number of drives; 90+
I will be controlling the start/rev/running/fault from digital I/O but I would like to write setup parameters and speed control over profinet.
Lets take the example that I use a Siemens S7 1500 top spec and for drive I use Danfoss FC302 with MCA120 profinet cards added, off the top of my head I think the PLC stats state 64 profinet devices.
I believe there are two methods of profinet comms. One method is a cyclic update and I think I am limited to the number of profinet devices mentioned in the PLC stats. Another method is periodic update.
Is it possible to set any device to do a periodic update over profinet and therefore have a virtually unlimited number of devices and if so how.
