Function: VBG-PB-K25

The VBG-PB-K25 is a PROFIBUS Gateway in accordance with AS-Interface Specification 3.0 and to IP20. The compact construction makes it particularly suitable for use in the control cabinet.

The VBG-PB-K25 is a modular PROFIBUS Slave. This means, that the PROFIBUS configuration tool can be used to determine which data are to be transferred via PROFIBUS. The quantity of data to be transferred via PROFIBUS can be adapted by this means.

This gateway supports the acyclic communication of the PROFIBUS DP V1. With the help of this acyclic service a mail box in the gateway for both AS-Interface masters can be addressed, via which all data made available by the AS-Interface/PROFIBUS gateway can be accessed. Address assignment, acceptance of the set configuration, the setting of the PROFIBUS and baud rate are possible via push button. 7 LEDs, mounted on the front, indicate the current status of the AS-Interface network.

This gateway can be used to keep the commissioning of the AS-Interface circuit, as well as the test of the connected peripherals, completely separate from the commissioning of the PROFIBUS and the programming. Local operation using the LED display and the 2 buttons enables all the functions to be represented, which are covered by the other gateways via the AS-i Control Tools software.

PLC functionality

Optionally the gateway is also available with PLC-functionality. Therefor you can order a code key VAZ-CTR additionally.
