Details
S100 I/O is the group of input and output boards located in the I/O subrack. The I/O subrack communicates with the controller subrack using Bus Extension to S100 I/O. Single and redundant Bus Extension to S100 I/O are available. Redundant S100 I/O Bus Extension requires redundant processor module. Electrical and optical bus extensions are provided. See the outline presentation of the bus extension in Section 1.7.7, Communication or to the separate documentation mentioned. Information in this section is divided according to the different categories of boards and subdivided into.
Regarding connection units and internal cables used in the hazardous and HART applications you are referred to the separate documentation.
All digital inputs are opto-isolated from the system potential. Grouping of channels, with respect to isolation, can exist. See information given with the actual board type and connection unit type. • You can select the mode of data base updating, either by interrupts or by scanning. The scan cycle times are normally selected from the range 10 ms to 2 s. • Some boards offer pulse extension, for example to avoid rapid scanning of push buttons. • The input signals are filtered on the input board to suppress the effects of electrical interference or bouncing contacts. The filter time is fixed to 5 ms or configurable depending on board type selected. • Board types offering interrupt-controlled scanning are most suitable to get time-tagged events.
