We have an application whereby we receive approx 6k of ascii data from a serial device. We have created a protocol within CX Protocol and this works fine when receiving at 9600. We have no address, header or CRC defined, thus only raw ascii is received.
We seem to have problems receiving at 19200. Keep getting a "Framing Error" bit within PLC from SCU21 module. Any suggestions??
Data is being transmitted from a PC running hyperterminal (for testing purposes)
Also, any protocol examples with variable recieve lengths would be good to compare. We dont seem to be able to get ours to work correctly. We need exact data length otherwise protocol step is ignored.
Longwinded but hope someone can help.
