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.

g

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.
