Comau C3G Plus - Examples of Use of System Signals Dedicated to Transfer Interface; Programme Number Selection from Remote through User-Programmable I;Os

EXAMPLES OF USE OF SYSTEM SIGNALS DEDICATED TO TRANSFER
INTERFACE
EXAMPLE OF PROGRAMME NUMBER SELECTION FROM REMOTE THROUGH
USER-PROGRAMMABLE I/O’s
(1) User-programmable I/O’s (IOM). The signals described are for example purposes and
may be used within a programme for work cycle management.
(2) Control unit initial status: status selector in the Automatic remote position .
(3) If there are no activated programs, START control is not effective and this OUTPUT
remains FALSE.
(5) Another solution for checking the PROGR. CODE consists in sending the C3G a parity
signal which will be checked by the PDL2. In this way, the outputs that provide echo of
the programme code are saved (REC. PROGR. CODE).
