Scanning Of Printer Status; Sending A Display Line To The Recorder F2H - ABB PointMaster 200 Series Operating Manual

Scanning of the printout status
The number of lines in the printout queue is scanned by the
recorder with:
SD3/DA/SA/FC/aa/oo/oo/cc/xx/xx/xx/xx/FCS/ED
|<-- L
Where:
SD3 = A2H
Start byte
DA Target address (bus subscriber address)
SA Source address
FC = 15H
Function code
aa = F1H
Basic address of the parameter field
oooo = 00 00H
2 bytes of parameter address (Offset)
cc = 01H
Number of scanned data bytes
xx xx
xx xx 4 random bytes
FCS Test byte (Frame Check Sequence)
Sum of the hex value of the L frame without transfor-
mation for FFH
ED = 16H
End byte (End Delimiter), code: 16H
L Number of Bytes in FCS

Sending a display line to the recorder F2H

This message is used to send a text line with max. 16
characters to the recorder. The message appears on the display
if the control byte is set to the value 01H.
The message format is:
SD2/LE/LEr/SD2/DA/SA/FC/aa/bb/cc/dd/ee/[Text line]/FCS/ED
|<--
26 Creating text blocks

The answer of the recorder is:
SD2/LE/LEr/SD2/DA/SA/FC/aa/FCS/ED
Where:
SD2 = 68H
Start byte
LE Number of data bytes + 3
LEr Repetition of LE
SD2 = 68H
Repetition of start byte
DA Target address (bus subscriber address)
SA Source address
FC = 15H
Function code
aa Number of information items in the queue
FCS Test byte (Frame Check Sequence)
Sum of the hex value of the L frame without transfor-
mation for FFH
ED = 16H
End byte (End Delimiter), code: 16H
L Number of bytes in FCS
Where:
SD2 = 68H
Start byte
LE = 17H
Number of data bytes + 7
LEr Repetition of LE
SD2 = 68H
Repetition of start byte
DA Target address (bus subscriber address)
SA Source address
FC = 16H
Function code
aa = F2H
Basic address of the parameter field
bb = 00H
Fill byte
cc = 00H
Fill byte
dd Length of the text line + 1
ee Control for display
00H = do not display text
01H = display text
