3.3 Driver installation
In the document “Quick installation PC boards” (see PDF link), you can get information on the
selection of the appropriate driver and on the driver download.
The most important information on the installation of drivers of the type “ADDI-DATA Devices Driver
Multiarchitecture 32-/64-Bit for x86/AMD64” as well as on the installation of the corresponding
samples is to be found in the installation instructions (see PDF link).

Function description APCIe-040
4Function description
4.1 One or two-level alarm system
With watchdogs 1-6, a one-level alarm system can be implemented and with watchdog 0, a two-level
alarm system.
Via watchdog 0, the first alarm level can be released. This means that a warning relay is switched
(closing contact) and/or an interrupt is released after the watchdog has run down.
In the interrupt routine, a user application may analyse the reason why the watchdog has run down.
If the reason should not be found during a programmable delay, the second alarm level can be
released by switching the reset relay.
In addition, the internal computer temperature can be monitored over the onboard temperature
sensor (see Chapter 4.7).

Function description APCIe-040
Application example
In a computer system, different tasks (application programs) are monitored.
Task 1 triggers watchdog 0 (reload value = 100).
Task n
Watchdog 0
100 (Reload value)

50

…

Task 2Task 1
If Task 1 is blocked due to a system error, the watchdog trigger is not released and watchdog 0 runs
down. After the watchdog has run down, a yellow warning lamp is switched on via the warning relay.
In the interrupt routine, a diagnostic program is started which analyses the reason for the blocking of
Task 1.
In case the diagnostic program cannot find the reason for the problem during a programmable delay,
the reset relay is switched. This closes the hardware reset contact of the computer system and thus
restarts the computer.
4.2 Digital inputs (24 V
The board APCIe-040 has seven digital inputs over which watchdogs can be triggered or timers can be
started or stopped (see Fig. 4-1).
Table 4-1: Function range for each input
Function Meaning Options
Watchdog trigger Triggers the watchdog. Reacts to “0” and/or to “1”
(24 V) at the input.
Timer gate Starts or stops the timer. Reacts to “0” and/or to “1”
(24 V) at the input.
www.addi-data.com 18

Function description APCIe-040
The digital inputs acquire external signal statuses. The input information is loaded as a numeric value
in a memory cell of the system via the driver function. This numeric value represents the status of the
input signals.
The inputs correspond to the 24 V industry standard (IEC1131-2):
•Logic “1” corresponds to an input voltage > 19 V.
•Logic “0” corresponds to an input voltage < 14 V.
The current demand for each input is 5-8 mA at nominal voltage (see Chapter 7.4.1). The maximum
input voltage is 30 V.
i IMPORTANT!
The mains supply for the external power supply of the board must
deliver at least the power that is required for your application.
The input signals are filtered by TVS diodes, RC filters and opto-couplers. In this way, the effect of
inductive and capacitive noise is reduced.
4.3 Digital outputs (relays)
The switching principle of the relays is explained in Fig. 3-7. Each output can switch a maximum current
of 2 A.
The warning relay and the reset relay functions are software-selectable. For the digital outputs,
positive logic is used:
•Logic “1“ = Set output (connection: change-over contact with closing contact)
•Logic “0“ = Reset output (connection: change-over contact with opening contact)
4.3.1 Watchdog 0
When watchdog 0 has run down, warning relay 0 or the reset relay is switched (see Fig. 4-2). The reset
relay can be switched in two different ways:
•Mode 0: The reset relay is first reset and after 2 s set again.
•Mode 1: The reset relay is first set and after 2 s reset again.
4.3.2 Watchdogs 1-6
When watchdogs 1-6 have run down, warning relays 1-6 are switched. The latter can be reset by a
computer reset or a reinitialisation of each of watchdogs 1-6.

Function description APCIe-040
www.addi-data.com 20
4.4 Watchdog
Using a software function, the 8-bit watchdog can be initialised and enabled.
The watchdog is started by the first trigger command (through software or via the digital input). This
means that the watchdog time is loaded and the watchdog starts to decrement.
In the program loop within the program to be monitored (software tasks), the trigger command has to
be called up in cyclic intervals, which prevents the watchdog time from elapsing. The watchdog time is
reloaded then and the watchdog decrements again. If the program has crashed, the trigger command
is no longer executed and the watchdog runs down. In this case, the configured alarm level is released
(see Fig. 4-1).
The watchdog statuses can be read back through software via status registers. Four units (μs, ms, s,
min) are available as time bases for the watchdog.
4.5 Timer
Independently from the PC clock, the timer provides a time base to synchronise operations, for
example. The timer is a downward counter which can release an interrupt after the programmed cycle
time has elapsed (time-out).
The seven timers of the board APCIe-040 can be programmed individually. The starting time of the
timer and the selection of the cycle time depend on the execution speed of the computer and on the
time parameters of the program to be monitored.
When the start value (reload value) of the timer is programmed, the timer is started by setting the
gate through software or via the digital input.
The current timer value and the start value (reload value) as well as status and interrupt registers can
be read back through software. Four units (μs, ms, s, min) are available as time bases for the timer.
Example
Reload value = 7
Initialisation with a rising edge
Interrupt enabled
When the timer value is “0”, the reload value “7” will be reloaded with the next valid edge and an
interrupt will be released.
