10.9 Contact switch
Switching of lines and basic logic operators between
Line
and
Flag
Latching key
Latch function for the input. The state of the outputs is toggled if the input
line is switched on briefly.
Keylock
To secure the function of a station, if a mechanical key switch is installed.
The selection cancels the blocking of a station if a key is pressed
continuously.
Input
Address, port and line
Output
Address, port and line
Long distance line line pool
Expansion of the range from 120 to 255 lines by using special lines. (only on
own long-distance lines between ProCom systems)
Flashing (call station / 24Li)
Use of the
Flashing
(only stations/24LI)line type
Repeat
To transmit special lines cyclically (only for existing systems)
(replaced by
Flag (NAND)
[IN] The program can be turned off by this flag or switching on can be
prevented.
Flag (AND)
[IN] AND-linking with
Flag (OR)
Flag (OR)
[IN] The program can be switched on by this flag.
Flag (OR)
(
Latching
)
[IN] The program can be switched on by this flag. It remains active even if
the flag is switched off again. Only when the flag is next switched on is the
program deactivated.
Flag (OUT) 1/2
[OUT] The flag is switched on if the program is activated. Other programs
can be triggered.
Flag (OUT) (Pulse with start)
[OUT]
Flag
is ON for a CPU cycle if the program is active
Flag (OUT) (Idle)
[OUT]
Flag
with a negative state of the
Flag (OUT)
10.10 System time
The internal clock can be synchronized to an external 24 hour time cycle.
Input
Address, Port,
Line
Address, port and line of the incoming time pulse
The time pulse can come as a line via a long-distance line from a neighboring system or
be received directly at IO modules (24LI, 4IOS) from third-party systems.
Time
The new time that is set in the system when the pulse becomes active
Flag (NAND)
[IN] The program can be turned off by this flag or switching on can be prevented.
