4.4 Configuring the display of messages in the header
Function
Using the PLC (also see the Chapter Cross-channel status display with icons), it is possible
to configure a two-line text display to appear in the "Program name" field in the header of
JOG and MDA modes (e.g. selected slide, activated handwheel).
Syntax:
The message texts can consist of:
● A language-specific part (from alarm/message text file *.COM)
● Three parameters (%1, %2, %3)
The maximum length of the texts to be displayed is 30 characters per line.
User PLC-DB
The display must be configured via a user PLC data block.
The number of the DBx with DBBy must be entered by the user in the HEADER.INI file as
follows:
[UserTextInfo]
USER_TEXT_BASE=DBx.DBBy
with x data block number, y starting byte in the block
If this interface is specified, the text length limiting must also be activated.
Textlength = 33
The name of the PLC alarm text file (e.g. "alpu_") should be entered by the user in the
MBDDE.INI file in the [TextFiles] section under "UserPLC":
[TextFiles]
UserPLC=alpu_
User DB interface to PLC
Two lines in the header can be used for the display:
● Program path line
● Program name line
The interface of the user DB provides a start data byte (job ID by the HMI) and subsequent
bytes with the objective that an axis index and a text (length, 12 characters/special
characters) can be output.
If "00" is written to a byte during text input, the HMI interprets this as the end of text. Entries
after this "00" entry are not displayed.
