9.6.5 Select program number
This command changes the program or switches to the processing mode with the specified
program number, provided this was assigned.
String
"MR<programnr>" (Machine command Run program <programnr>)
Table 9- 56 String structure
Characters Description
<programnr> Number of the program saved.
•
Two printable ASCII characters with the value "0" to "9".
• Valid range of values: 00 ... 15.
This command returns no response string.
•
Using the "Query status" command, you then check if the
program change has been successful. If, for example, pro-
gram number "5" is selected and the status is queried, the
string "MR05MGST" can be sent.
• Using <statusbyte> and <currentcodeno>, you can check
whether the optical reader is in processing mode with the
new program number.
If the DISA bit is not set already, the optical reader will set it au-
tomatically to save the program and then reset it.
9.6.6 Save program with internal trigger
Note
Requirement
To be able to execute this command, you first have to configure the identical transport
connection as the trigger and control source.
This command starts the program saving procedure and internally generates a trigger for
image acquisition. The code is saved with the specified number.
Note that if a program has already been saved with this number and no error occurred during
the save procedure, this program is overwritten. If the save procedure is successful, the
optical reader then goes into processing mode with the relevant program number.
