Dear All, I'm working to make an IOC which has to read strings on rs232; these strings are continuously sent from a box. Up to now I'm working just only to read the this string: "KS,[counter],[encoder0],[encoder1],[encoder2],[encoder3]" The IOC works very well to few hours, after that it's (the communication) hangs-on (??) Follow the protocol: ---------- InTerminator = LF; # ExtraInput = Ignore; ReplyTimeout = 1000; ReadTimeout = 1000; LockTimeout = 5000;
Note that StreamDevice needs to poll the serial interface for new data when using "I/O Intr". The default for PollPeriod is ReadTimeout, which you set here to 1 second. That may be too long. Have it shorter than the expected repetition rate.
knob_id { in "KS,%d,%*d,%*d,%*d,%*d" ; }
knob_0 { in "KS,%*d,%d,%*d,%*d,%*d" ; }
knob_1 { in "KS,%*d,%*d,%d,%*d,%*d" ; }
knob_2 { in "KS,%*d,%*d,%*d,%d,%*d" ; }
knob_3 { in "KS,%*d,%*d,%*d,%*d,%d" ; }
As Peter suggested, use redirection. Dirk
