AS-Interface Gateway/Safety Monitor VBG-PB-K30-DMD-S16-C1

The VBG-PB-K30-DMD-S16-C1 is an IP20-rated PROFIBUS gateway with an integral safety monitor and a double master according to AS-Interface specification 3.0. The VBGPB- K30-DMD-S16-C1 has four inputs and four outputs. The four inputs are used either for extended EDM device monitoring or as start inputs. Two sets of two outputs act as relay outputs and switch output circuits 1 and 2 and, as semiconductor outputs, output circuits 3 and 4. Due to integrated decoupling coils, one switching power supply, for example the K24-STR-24...30VDC-10A, can supply 2 AS-Interface lines at the same time. The K30 model is particularly suitable for installation in a control cabinet.

The VBG-PB-K30-DMD-S16-C1 is a combined full-specification AS-Interface PROFIBUS gateway and safety monitor. The product allows a gateway and a safety monitor to be used in a single device. Two safety relays provide a safe interface to the connected consumers. The AS-Interface 3.0 PROFIBUS gateways are used to connect AS-I systems to a higher-level PROFIBUS. They act as a double master for the AS-I segment and as a slave for the PROFIBUS. The AS-I functions are made available on both a cyclic and acyclic basis through PROFIBUSDP V1.

During cyclic data exchange, up to 32 bytes of I/O data (this amount is variable) are transferred as the digital data of an AS-I segment. In addition, analog values as well as the complete command set of the new AS-I specification can be transferred via PROFIBUS using a command interface. Monitoring of the AS-Interface data can be carried out online via PROFIBUS-DP V1 using the serial PROFIBUS master and the AS-I Control Tools. Address assignment, the transfer of the desired configuration and the setting of the Profibus address and baud rate can all be performed using switches. Seven LEDs located on the front panel indicate the current status of the AS-Interface segment. One LED shows the power supply via AUX. A further eight LEDs indicate the status of the inputs and outputs.

A further eight LEDs indicate the status of the inputs and outputs. If the AS-Interface gateway has a graphical display, the commissioning of the AS-Interface circuit and testing of the connected peripherals can take place completely separately from the commissioning of PROFIBUS and the programming. Local operation using the graphical display and the four switches allows all the functions covered on the other AS-Interface masters by AS-i Control Tools software to be visualized on the display. An additional RS 232 socket provides a way of exporting data relating to the gateway, network and operation directly from the gateway for extended local diagnosis purposes.
