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.

7.2.3.2 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).
