5.3 Reading in data (indicating values)

The indicating values are saved in a PLC data component of the S5 data memory. It is obliga-
tory to state DB3 in the programming package COM 525 when determining the orders for
measurement loops 1 … 128 and DB4 for measurement loops 129 … 255. See also chapter
5.1. Here also the data destination, e.g. source data component 3 from source word address
0 is stated.

Saving of the VEGAMET data in a PLC data component

The data words 0 to 12 are reserved and are not used. 2 data words (4 bytes) are required
per indicating value. Each VEGAMET provides 7 indicating values. These are saved in the
data component as follows:
