This document solely describes the function “Pulse counter”.
For general information on the APCI-1710 or CPCI-1710, please read the Technical Description of
these boards (see PDF link). It contains, for example, the chapter “Inserting and installing the board”
that supports you in commissioning.

Function description PCI-1710: Pulse counter
1Function description
The “Pulse counter” function is an interface for the acquisition of external digital pulses.
Up to 16 pulse encoders can be connected to the board, i.e. up to four pulse encoders per function
module.
The pulse counter is a downward counter. It starts when the programmed counter value has been
loaded and the gate bit has been set. After that, the counter decrements with every valid edge (rising
or falling) at the counter input. When the counter has run down, an interrupt can be released. With
counter 0, it is also possible at this point to set or reset the digital output.
In Continuous Mode, the counter will be restarted afterwards.
Features:
•4 function modules, each with 4 pulse counters (32-bit)
•Processing of up to 5 MHz signals
•Optical isolation of the inputs and outputs through opto-couplers to prevent ground loops
•Function and control logic
•2 counter modes:
¾Single Mode: When the counter value is “0”, the counter is stopped.
¾Continuous Mode: When the counter value is “0”, the reload value will be reloaded with the
next valid edge.
•4 separate 32-bit registers, which can be read out via the PCI bus
1.1 Board versions with “Pulse counter” function
NOTICE!
The “Pulse counter” function can be used with every version of the
APCI-1710 or CPCI-1710.
The I/O specifications of the different board versions are available in the Technical Description of the
APCI-/CPCI-1710 (see PDF link).

1.3 Used signals
With each function module, the “Pulse counter” function uses four inputs (A to D) and one output (H).

1.5 Connecting the pulse encoders
1.5.1 Connection to the screw terminal panel
On the screw terminal panel PX8001, the pins of the 50 pin D-Sub female connector and the terminals
connected to them are numbered in the same way. Thus, the terminal assignment of the screw
terminal panel is identical with the pin assignment of the 50-pin D-Sub male connector of the
APCI-/CPCI-1710.
The following table is to serve as a help for you when connecting the pulse encoders to the screw
terminal panel. The blank fields in the “Pulse encoder” column can be filled in on the basis of the
selected pulse encoder type.

1.6 Procedure for using the “Pulse counter” function
In order to use the “Pulse counter” function, the following steps need to be performed:
1. Program the counter value (= reload value) of the downward counter.
2. Select the edge (rising or falling) of the counter input signal that should count.
3. Define the action(s) to be performed when the counter has run down: Release interrupt; set or reset
output (only with pulse counter 0).
4. Select the counter mode (Continuous or Single mode).
5. Enable the counter via the gate bit.
