Function

The VBG-MOD-K20-D is a MODBUS RTU

gateway in accordance with AS-Interface-

Specification 3.0 in IP20. The design makes it

particularly suitable for use in control cabi-

nets.

The AS-Interface data can be used in many

varied ways and for a variety of purposes. All

the important data are available in both binary

form as well as packed and unpacked via a

register. So that the AS-Interface gateways

can be operated with the MODBUS slave

interface by the most varied of MODBUS

masters, without having to resort to expensive

adaptions. The gateway is supplied from the

AS-Interface cable.

The assignment of addresses and the accep-

tance of the set configuration is possible by

means of push button keys. 7 LEDs, arranged

on the front of the device, indicate the current

status of the AS-Interface network.

On the AS-Interface Gateway, with graphic

display, the commissioning of the AS-Inter-

face circuit and the testing of the connected

peripherals can be completely separated

from the commissioning of the MODBUS and

the programming. On-site operation using the

graphics display and the 4 buttons enable all

the functions to be depicted on the display

that are covered by the other AS-Interface

masters via the AS-i Control Tools software.

An additional RS 232 socket provides the

option of reading out data directly from the

gateway, on gateway, network and function in

the context of an extended on-site diagnosis.

PLC Functionality

Optionally, the gateway can be supplied with

PLC functionality. Therefor you can order a

code key VAZ-CTR additionally.

Notes

In an AS-Interface network only one device can be operated earth fault detection. If there are

many devices in an AS-Interface network, this can lead to the earth fault monitoring response

threshold becoming less sensitive.
