IO Capacity of Freelance AC800F Control PM802F
In my system I have approximetaly 3800 IOs as details AI:437,AO:190,DI:1762,DO:1246,RTD:186.
the controller must be reduandancy.I want to know that how many controller we need for mentioned IO?As I know that the typical IO support for AC800F is 100,But its a nominal value and I think that t1000 IO is more precise for PM803F not PM802F.
In short with PM802F CPU how many IO can be supported with regarding the controller reduandacy is need.
Thanks very much
Controller can not be sized just based on IO, there are many factor needs to be considered. like task cycle time, CPU load, Memory usage... for sure all this is dependent on I/O but inter dependent. And there is tool available called Freelance calculation tool will help in sizing controller. Get connect with ABB support people.
Typically AC800F supports 1000 to 1200 I/O. But again this is like on all default setting. as said previously there are lots of factor to be considered. Hope that helps...
