System components: Field controller SFC162

The SFC162 Field Controller together with a backplane power supply, fieldbus power supply and fieldbus power conditioner form the basic controller assembly. By adding I/O modules it is possible to integrate conventional discrete and analogue signals. Each Field Controller can directly access 256 I/O points distributed among local I/O modules. The Field Controller supports continuous, discrete and hybrid control with up to 100 function blocks. Five of these are always required by the controller and max. 50 can be hybrid blocks. In normal operation, it acts as a Link Active Scheduler (LAS) for the H1 segments, maintaining a live list, controlling the cyclic and acyclic traffic, publishing the time stamp etc.. It is designed for HSE operation and H1-H1 and H1-HSE-H1 bridging.
