BITS N BYTES Posted June 17, 2015 Report Posted June 17, 2015 Use "No-Protocol" with TXD(236) and RXD(235). Applying these instructions is described in manual W451. Quote
kliktito Posted June 18, 2015 Author Report Posted June 18, 2015 I have already to try but it not working with this setting, DIP SW Setting on PLC : 1,2,3,4,5,6 = OFF DIP CP1W-CIF11 : 1,2,3,5,6 = ON & 4 = OFF is there something wrong? help me.. Attached Thumbnails Quote
Michael Walsh Posted June 18, 2015 Report Posted June 18, 2015 I would have dip switches 4, 5 and 6 OFF on the CIF11 and then your data string would need to have a CR+LF as a terminator. Of course the Baud rate, parity, data bits and stop bits would need to match on the other device. Quote
kliktito Posted June 25, 2015 Author Report Posted June 25, 2015 Okay.. Thankyou very much Mr. Michael Walsh & Bits n Bytes..:) Quote
