Open interface description NE215 7 Open interface description 7.1 General information The open interface is of the RS485 type. It is possible to send the commands documented in the „Description of the Open Interface“ for remote control to the counter. The interface allows to call up data and to change the programming of parameters not relevant for the values to be calibrated.
Open interface description Important NE215 The blanks between the particular characters of the commands only serve the purpose of better legibility. The input at the PC must be effected without blanks. Control characters (less than 20Hex) are set in „pointed“ brackets. If a false protocol has been sent by the PC, the counter will return an error message. Please read the paragraph regarding error messages on page 29 under 7.7. 7.
Open interface description NE215 The protocol: Address line P [VZ] data [] can be used for each line. The answer of the counter that is returned after every programming step is the same as for the readout of the line. All storage locations may, principally, be programmed during the RUN mode in the programming mode. Please refer to page 27 (under 7.5.2) to find out how to switch to the PGM mode. Programming command (general): Address Line P [VZ] Data [] 7.4.1.
Open interface description NE215 7.5.2 Switch counter to PGM mode or RUN mode This command allows you to switch the counter upon every call between the PGM mode and the RUN mode. The current line, as with the reading command on this line, will be returned as an answer. General: Example: Command: Answer: Address Address=35, Status=RUN mode, Current line = 1, Count=0.
NE215 Open interface description 7.6 Output to the printer The command parameter „D“ allows the initiation of the output of the lines 01, 02, 03 and 05 to the printer. 7.6.1 Appearance of the printout The printout comprises - date and time that need to be sent along by the PC upon a print command - optionally further data, which the PC may send along - the length measurement needing to be calibrated, indexed by the sign * . Example: 29.08.94 10:30:45 LENGTH*000123.45m 7.6.
NE215 Open interface description Answer: 3501D4 7.6.4 Printout of the lines 02, 03: preselections P1 and P2 As these are not length measurements that need to be calibrated, the value of the preselections P1 and P2 is not printed with the sign *, and it is also not necessary that the PC sends Date/Time along. Example: Counter address=35, Line=02, P1=1.00 Further data=29.08.94 10:33:18 PC Command: 3502D29.08.94 10:33:18 Printout: 29.08.94 10:33:18 P1 1.
Open interface description NE215 General structure of the error messages: Address Line Status Error number Example: Address=35, Line=09 (invalid line), Error number=2 3509R2 The two positions „Line“ and „Status“ will not occur with the special commands. Error description in particular: Error 1: Format error ( not at the right place). This error might happen, for example, if the data format was not observed when programming (e.g.
