BK40x0 (Interbus)
The BK40x0 Bus Couplers are used for InterBus. Those specific properties which distinguish them from other Bus Couplers are described below. For an Overview of currently supported Interbus Bus Couplers BK4xx0, ...see
”BK4xx0” tab
Identity Code: Displays the identity code for the Bus Coupler. It is calculated dynamically - according to the connected terminals.
Length Code: Displays the length code for the Bus Coupler. It is calculated dynamically - according to the connected terminals.
Installation depth: Displays the installation depth of the Bus Coupler. It is calculated dynamically - according to the hierarchical structure of the InterBus-S.
Diagnostic: Inserts two bytes of diagnostic data into the process image per input and output (see BK4000 manual).
2 Byte PLC interface: Inserts two bytes of PLC interface into the input and output process image
Input Diagnosis
Each InterBus-S box contains one diagnostic input byte which signals the status of the current slave during the running time and can be linked, for example with the PLC.
