Function

The VBM-CTR-K20-R2 is a stand-alone mas-

ter in AS-Interface specification 3.0 with IP20.

The construction type is especially suited for

use in a switch cabinet.

Address allocation, acceptance of the target

configuration and setting the baud rate can be

managed via buttons. There are 7 LEDs on

the front panel, showing the current status of

the AS-Interface line.

In the AS-Interface master with graphical dis-

play the commissioning of the AS-Interface

circuit and the test of the connected periphery

devices can be separated completely overri-

ding bus systems and from programming.

The on-site operation via the graphic display

and the four push buttons make it possible to

show all of the functions on the display,

which, for all other AS-Interface masters, are

covered by the software AS-Interface control

tools.

PLC Functionality

For PLC functionality the VBM-CTR-K20-R2

provides 16 kB program memory, 8 kB data

memory, 1024 counters and 1024 timers.

This is sufficient capacity to process all data

arriving at the AS-Interface. The master can,

therefore, also be operated as "stand-alone".

The programm processing for 1000 word

commands is approx. 2 ms. The program-

ming language is based on STEP5. In the

extended mode the AS-Interface CTRL func-

tions (upload, download, start, stop, read and

write marker) can be utilized.

Approvals and certificates

UL approval

An isolated source with a secondary open circuit voltage of ≤

rent protection is not required when a Class 2 source is emplo-

yed.

UL mark does not provide UL certification for any functional

safety rating or aspects of the device.

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.
