Introduction

The KL6781 M-Bus master terminal enables direct connection of M-Bus devices. The M-Bus (meter bus) is a fieldbus for consumption data acquisition from electricity, water, gas or energy meters.

The KL6781 does not contain the M-Bus protocol but converts the K-Bus data to an M-Bus compliant format. On the K-Bus, 24 bytes are available for this purpose for each M-Bus master terminal.

The TwinCAT M-Bus library enables operation without external M-Bus gateway, i.e. the M-Bus devices can be connected directly to the KL6781.

With a total line length of 300 m, up to 40 M-Bus devices can be operated at a KL6781.
