Data set variables:
Key: SDW
Parameters: Offset of the variables in the recipe, variable size in bytes, value of the
variables (as a hexadecimal string)
End of data set identifier:
Key: SDE
Parameters: none
Explanations:
Recipe Version Number:
On creating or changing the recipe description in the programming system, this
version number is increased automatically whenever the structure of the data sets
has changed. To be able to load a data set from the PC to the operating terminal,
the downloaded version number and the version number stored in the operating
terminal for the recipe involved must match. The downloaded data set will not be
stored if they do not match.
Write-over identifier:
The value 1 means that the downloaded data set is to overwrite any data set with
the same number that may already exist in the operating terminal. The value 0
means that the downloaded set is to be rejected if a data set with the same number
already exists. Only those data sets can be overwritten that are not stored in the
Flash memory, i.e. that were loaded into the terminal together with the user de-
scription.
4.8.5 Printing Data Sets
The data set printout can be started from both the operating terminal and the con-
troller.
To be able to initiate a printout from the operating terminal, either the system var-
iable StartRezPrint must be placed into a mask or a soft key must be assigned
accordingly. The active data set can be printed via SER2 by writing the value 1 to
the system variable.
Writing the value 2 to the same system variable will cancel the print process.
A heading including the recipe number, data set number and data set name will be
printed at the beginning of each data set.
The status of the print process can be indicated via the system variable RezPrint-
State.
To be able to control a print job from the controller, the data set number and recipe
number must be entered into the appropriate variables first. The print job is then
started by writing the value 7FF8H to the address of the serial message channel. A
value of 0 (zero) in the variable for the recipe number (for request from the terminal)
will indicate that the data set is being printed.
If another print job is currently being printed so that the printer can not print the
specified data set, the value 255 will be written to the variable for the recipe number
(for request from the terminal).
