18.2 L1WRIT ( write level1 data )
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, exter-
nal set-point and two alarm limits) and the control information (automatic/manual, w/W2, Wint/Wext and y/Y2) avail-
able to the engineering. These data can be written in a message via interface.
