4.9.2.3.1
Full-Page Message Output
The full-page message is a combination of message processing and external mask
selection. For a full-page message mask output, a mask and a message text must
be programmed under the same number. The controller calls up the ‘external
mask’ through the serial message channel. When it is called up, the mask is dis-
played and the associated message text is entered into the message memory. As
the display contents can be chosen freely, it is possible to realize a message mask,
a full-page error output or other contents types. To be able to return to the previous
menu from here, at least one mask parameter must be programmed for ‘Previous
mask’. Message masks can also consist of several masks or even complete struc-
tures for troubleshooting.
It goes without saying that a separate, full-page help text can also be programmed
for each full-page message.
4.9.2.3.2
Messages Directly to a Logging Printer
When serial messages are logged directly, the printer always runs synchronously.
Every new message arriving via the serial message channel is printed immediately
and is transferred to the message memory in parallel. Here, attention must be paid
that the printer can only process one print job at one time. Every print request must
be ended before any further print request is started by the system.
The output of the messages to a printer can be influenced by the system variable
RepmanRepPrint.
The settings that apply when the formatted type of printout is selected are the same
as those selected for the display of messages in the message mask.
The settings for the printout can be changed on the terminal during operation.
As the output consists of a pure text file, the message can also be read by a host
computer or a PC. With a further system variable PrintAllRepLong, the full length
of the message can be output.
4.9.2.3.3
Erasing the Message Memory Externally
The internal message memory of the serial message system can be erased ex-
ternally, that is from the controller. To do this, a symbolic variable name for the
deletion variable must be specified in the Message System option of the param-
eters file using the programming software. Two bytes are needed in the controller
for the variable.
The terminal always checks the deletion variable in the controller once it has re-
ceived the deletion sequence (deletion code 7FFE
H
via the serial message chan-
nel). The internal message buffer is deleted if the deletion variable contains the bit
pattern E216
H
. The deletion variable increases protection against unintentional de-
letion.
If deletion is not required, the variable should be reset or no symbolic name should
be specified in the programming software.
