Standard Mode
however, they can be reloaded into the operating device again after the
application description has been loaded. If changes have been made
to the structure of any of the recipes (number of variables, position of
the variables in the data set buffer, etc.), only the data sets of the other,
unchanged recipes can be reloaded into the operating device .
The data sets are transferred in a format that can be edited using a
Text Editor (see section 3.8.4.3 Structure of the Data Set File).
The parameters for the X3 interface can be freely configured by means
of the corresponding system variables. Merely make sure that the
same parameters are set at the PC end. You can send or receive at the
PC end with any suitable program, such as Windows Terminal (1).
5.23.3.4 Transfer to a PC
The transfer of data sets to the PC is initiated by writing a value to the
system variable StartSave. The number of data sets that are trans-
ferred depends on the value that is written to the system variable. The
following are valid values:
System variable value = 1: Only the active data set is transferred.
System variable value = 2: All of the data sets of the active recipe are
transferred.
System variable value = 3: All of the data sets of all recipes are trans-
ferred.
The process can be monitored by the operator with the aid of the sys-
tem variable SaveState.
5.23.3.5 Transfer from a PC
The operating device is placed to the Ready-to-Receive state when the
system variable StartRestore is set to 1. The data sets can then be
sent by the PC. The operating device recognizes the end of the data
set transfer automatically by analyzing the data it has received. It then
returns to its normal state.
To cancel the Ready-to-Receive state again without receiving data, the
value of the system variable StartRestore must be changed to 2.
The system variable RestoreState indicates whether or not the terminal
is ready to receive.
If a formatting error is detected in the received data, a system message
to this effect is output and the receive process is terminated. The posi-
tion of the formatting error can be located, at least approximately, with
the aid of the system variable RestoreLineNr. This system variable
contains the number of the last line to have been received.
