Setup

Saving of measured values blocks in measured value data components

For saving the measured values, the data components DB220 to DB235 are set as a standard

feature. The Start data component can be set in DB240 in DW0 (standard: 220). The next 16

data components must be reserved for the measured values.

DB (measured value block) = Start data component + measured value block -1

Start data component = 220 (standard setting); measured value block = 1 … 16

Initialisation of the measured value data components (DB 220-235)

Each measured value block is saved in a data component. For the 16 measured value blocks,

16 data components with 16 measured values each are required. As a standard feature, data

components DB220 to DB235 are set. The Start data component can be set in DB240 in DW 0

(standard: 220). The next 16 data components must be reserved for the measured values.

The initialisation values must be entered in the data components.

A measured value consists of 4 octetts and one index and status information (6 octetts = 3

data words)
