Instruction Manual

III-10.2 L1WRIT ( write level1 data (No. 101))

General

This function is used to provide a data set transmitted by the interface to the engineering. The digital interface de -

scribes EEPROM cells with codes 31...39, function number 0. The data set comprises 8 analog process values (y1...y8)

and 15 digital control informations (z1...z15), which are provided to the engineering.

The transmitted data are stored in the EEPROM. After power failure, start is with the data rather than with the default

values.

Inputs/outputs

Digital outputs:

z1 ... z12

Digital process values, which can be written via the interface (default = 0)

Analog outputs:

y1 ... y8

Analog process values, which can be written via the interface (default = 0)

Engineering example

In the following example, the L1WRIT function block is used to make several process data (process values x2, x3, ex

ternal and two alarm limits) and the control information (automatic/manual, w/W2, Wint/Wext and y/Y2) available to

the engineering. These data can be written in a message via interface.
