APCI-1710 Functions of the board
47
One function module is a physical unit that consists of:
-
digital inputs
-
digital outputs
-
one function programmable component (hardware)
The function modules are also connected to each other through an internal
bus.
9.2 Digital inputs and outputs
9.2.1 Description
To each function module digital inputs and outputs are allocated firmly.
However, a few inputs also can be set as outputs for certain functions, which
are implemented on the function module.
8 lines are available for each module: (see Fig. 9-2: block diagram of digital
inputs and outputs) (1 function module)
The lines are divided according to the board as follows:
APCI-1710
Input lines
- 2 x TTL, RS422 (signals C, D)
- 3 x 24 V, 5 V optional (signals E, F, G)
Output lines
- 1 x 24 V, TTL optional (signal H)
Free definable lines (input or output)
-2 x TTL, RS422 (signals A, B)
APCI-1710-24 V
- 7 x 24 V inputs (signals A to G)
- 1 x 24 V output, TTL optional (signal H)
The function of the digital inputs and outputs depends on the function that is
programmed on the function module and is described respectively in the
corresponding documentations. The following sections describe only the
general characteristics of the inputs and outputs.
