I'm looking for a bottleneck. I have a micro-pc sends 41 bytes in СPU317-2pn/dp (firmware 2.6.7) every 20ms,CPU317-2pn/dp must pass every 20ms 17byte in micro-pc. I use ASCII protocol 57600baud on RS232. I have obtained the transfer (from cpu)of only about once every 50..60ms - I look at the oscilloscope. If micro-pc nothing passes, the transfer of CPUin 20 ms is obtained. I assumed that the bottleneck is the k-bus. although I may be wrong software programmer CP341. My programm work in OB35 with period 20ms I would also like to know - when the CPUwork with CP: after OB1 or at another time Splitted from speed of K-bus on 317 CPU. |

Thread closed, because question is already discussed in the following thread slow communication with cp341. Best regards O_Moderator |
