Product Description:
FCS are connected to each other and to human interface tations (HISs) and other stations and gateways via VLnet. ommunication over the VLnet enables FCS databases to be lownloaded and the various settings of an FCS to be set and read rom an HIS. It also enables an HIS to be notifed of alarms by the FCS. FCS are equipped with a number of different input/output (I/O) modules that connect the various analog and digital input/ output signals as well as general-purpose communication lines such as RS-232C to the FCS. The signals acquired by the I/O modules are subjected to input processing, control computation, logic operations, and then output processing before they are finally output from the FCS's I/O modules.
