2 Setting Functions and Parameters
Configuring OEM texts in the header
The machine manufacturer can display his own texts in the program directory and
program name lines. These texts cannot include % parameters as is possible in
user texts. The lines are divided into <OEM_NUMBER_TEXTFIELD> areas
according to the entry in HEADER.INI.

Channel RESET
STOP: No NC RESET

Figure 2-4 Example of OEM text
The data are provided in a user PLC DB. The number of the data block and the
exact offset are declared in the HEADER.INI file.
The following entries are available in the [OEMTextInfo] section for this purpose.
OEM_NUMBER_TEXTFIELD = 1 ; maximum of 3 text fields per line
OEM_TEXT_BASE = DBx.DBBy
The interface in the user DB has the following format:
Start-DBB Byte
Or
Start-DBB +18 Byte
Start-DBB +1
Or
Start-DBB +19
Start-DBB + 3 String
Or
Start DBB+20 Double Word
The first parameter contains an offset for a text number with a base of 700,000
(user PLC texts). If this parameter = 0, the corresponding line is deleted. The
second parameter contains a maximum 12-character string. Unless empty, this text
is output instead of the user PLC text.
The parameters must be written from "back to front" in the PLC, i.e., all parameters
must be initialized before the first byte is set. The data for the next line are located
exactly 18 bytes after the start byte. The lines are output from left to right; a
maximum of three output fields per line are provided (i.e., a total of 6 fields are
possible).
A hotlink to the first byte for each line is set up in the HMI. If a change occurs in
that byte, the HMI reacts. If the HMI has displayed the data, it writes a –1 to the
first variable. The HMI is informed about this change by means of the hot link,
whereupon it writes a 0 to this variable.
