Permissible limit of modules DC541-CM to connect with PM583
What is the permissible limit of modules DC541-CM (Or any other fast counter) to connect with PM5xx (or PM583-eth)? And what is the maximum PRACTICAL counting speed of this module.
In my application, my requirement to count 10 objects / seconds, and total fast sensors per line are 5.
Thanks in advance
Looking in your application data, 10 objects per second means 10 Hz frequency, which is low frequency. And a total of 5 channels required.
In case you use PM5xx, it has already 2 fast counters integrated (2 DI can be configured like fast counters).
In addition you will need additional 2 modules with integrated fast counters - look in S500 for that (DI524, DC522, DX522...) - such modules has 2 channels each, configurable like fast counters. Choose what you need, according to other signals required (DI, DO).
In case you plan to use PM583 or other AC500 CPU, then you will need 3 DI modules with integrated fast counters.
