7.2.1 Brief description
The 07 MK 92 R1161 communication module is a freely
programmable interface module with 4 serial interfaces.
The communication module allows external units to be
connected to the Advant Controller 31 system via a serial
interface.
The communications protocols and transmission types
can be freely defined by the user.
Programming is performed on a PC with the program-
ming and test software 907 MK 92.

2Hardware
The communication module is connected to AC31 basic
units via the networking interface, e.g. 07 KR 91 R353,
07 KT 92 (index i onwards) 07 KT 93 or 07 KT 94.
The most important features of the communication modu-
le are:
· 4 serial interfaces:
– 2 of them are serial interfaces, optionally con-
figurable in accordance with EIA RS-232 or
EIA RS-422 or EIA RS-485 (COM3, COM4)
– 2 of them are interfaces in accordance with
EIA RS-232 (COM5, COM6)
· Freely programmable with a comprehensive function
library
· Communication with AC31 basic unit via library func-
tions
· Configurable LEDs for diagnosis
· Programming and testing on a PC via COM3
Processing of the serial interfaces and the networking in-
terface is provided for in an applications program.
Programming is in the standard language ”C”.
The exchange of data between the serial communication
module and the AC31 basic unit is realized by function
blocks in the basic unit.

The status of the application program is indicated by the
LED RUN: The LED RUN lights up while the program is
being processed. If an error occurred during loading (e.g.
program not present), the LED RUN remains OFF.

If the switch is switched from RUN to STOP, the program
processing is aborted. The LED RUN goes out.

7.2.3.1 Application example for connecting
the inputs and outputs
The following illustration shows an application example
with the 07 KT 97 which utilizes various possibilities for
connecting inputs and outputs. Attention must be paid to
the following in detail:
· The earthing measures
· Connection of the 07 MK 92 communication module
· Looping through the supply voltage (24 V DC) from
the 07 KT 97 to the 07 MK 92
· Earthing the switch-gear cabinet mains socket
· Handling serial interfaces

7.2.3.2 Connecting the 24 V DC supply voltage
The supply voltage is fed in via a 5-pole detachable termi-
nal block.
Important:
Plug and unplug terminal block only with power off!
7.2.3.3 Electrical isolation and notes on earthing
The following illustration shows which circuit parts of the
unit are electrically isolated from each other and which
internal connections exist. Here, both the clearances and
creepage distances and also the test voltages used cor-
respond to DIN/VDE 0160.
The unit is connected via the 6.3 mm Faston terminal (bot-
tom left) to the functional earth (switch-gear cabinet earth)
via a wire with a cross section of 6 mm2(also see
Fig. 7.2-6).

7.2.3.4 Serial interfaces
Use
External units can be connected to the AC31 system via
the serial interfaces. The interfaces are independent of
each other. They can be managed via freely definable
protocols.
Scope of functions
The four serial interfaces can be configured independently
of each other in the following scope of functions:
· Data format 7 or 8 bits
· Even, odd or no parity
· Discrete baud rates
from 300 Bd to 19200 Bd for COM3 and COM 4 and
from 300 Bd to 9600 Bd for COM5 and COM6
· Automatic processing of the SW handshake
(XON/XOFF)
· Automatic processing of the HW handshake
(RTS/CTS)
· Error detection
(parity, framing, overrun, break)
Serial interfaces COM3, COM4
Interface standard
– EIA RS-232 or
– EIA RS-422 or
– EIA RS-485
Both interfaces can be run independently of each other in
one of the interface standards each. Selection is by choos-
ing the corresponding interface signals.
Modes
– Programming and test mode
– Application mode
COM3 can be used as a programming and test interface.
Electrical isolation
Both interfaces are electrically isolated.
Connection
Connection is via a 15-pole D-SUB connector (female).
