Examples
During installation of the engineering tools, several examples were included. These are in path:

Useful small engineerings
Cascaded counter with pulse generator(
ZAEHLER.EDG)
An INTE is used for generating pulses.
Max. parameter =1, time constant to 3600 sec.
An input value at x1 of e.g. 20 weighted via the MUDI generates 20 pulses per hour.
The first counter counts to 1000, the second counter counts the (1000s) overflows.
Simple password function
(PASSWORT.EDG)
A VWERT is used for password entry. The output is not fed back to the input, for suppressing display of the entered
value after pressing the enter key.
The current hour of the status block is used as a password (only with clock). The EQUAL block determines the condition
for disabling the parameter level.
Password from the CONST block
(PASSWORD.EDG)
A VWERT is used for password entry. The output is not fed back to the input, for suppression of the display of the en-
tered value after pressing the enter key. A value of the constant block is used as a password. The EQUAL block deter-
mines the condition for disabling the parameter level and display suppression of the VWERT page.
Macro for dynamic alarm processing
(ALARMSEL.EDG)
ASELV2 can be used to select one of 4 values for alarm processing.
An ALLV compares the value with an upper and a lower limit definable via a VWERT.
The alarms are displayed at the second VWERT and output to a relay via an OR. Each of the two VWERT can define or
display two further alarm limits. Therefore, the configuration can be extended by another ALLV. As an example, possi-
ble alarm acknowledgement via a flipflop is provided. Alarms are held in the LED display and the alarm line until ac-
knowledgment via the VWERT (alarms) .
Alarm acknowledgement of 5 alarm bits
(ALAMQUIT.EDG)
The flipflops hold the alarms individually until acknowledgement via the VWERT. The acknowledge output is fed back
to the Store input instead of the corresponding input bit.
Thereby, the acknowledge bit is reset automatically.
Alarm acknowledgement of 5 alarm bits,
which are not lost also after prolonged power failure
(ALQITSAV.EDG)
Flipflops are also used for storing. In this case, the status change of the flipflop must be stored in non-volatile recipe
blocks. Moreover, the flipflops must be loaded with the content of the recipe block for restoring the last status after
power recovery. In VWERT, the alarms are displayed and acknowledged, if necessary.
Further display via LED, DIGOUT and INFO.
Parameter number display via texts
(PRNRE.EDG)
The current parameter number (variable in VWERT) is compared with constants via EQUAL.
With equality, a bit at VWERT is set, whereby a digital text is displayed.
Two-point operation of a programmer
(RUNFLIP1.EDG)
As entry of commands via the operating page is not possible with a programmer, if the relevant digital inputs were con-
nected, the toggle key (fkey:a/m) must be used for realizing the Run/Stop order on the operating page. A monoflop gen-
erates a short pulse on the positive and negative flank. The external command (key or switch) from the control panel via
d1 is also taken via a monoflop. With a key, only d1 (positive flank) is connected, with a switch, d1 and d2 are con-
nected (positive and negative flank). The pulses are taken to a flipflop, which switches over between Run and Stop.
