hi remeeus, I am sure ther is a response. have a look to this: How do you evaluate the status of system blocks in STEP 7 (TIA Portal)?Status is just valid for one cycle. you can´t see it with bare eyes. hope this helps, regards, |

Why didn't i think of that.......Thank you very much! Okay, now we do have a response..... 80C8 witch indicates a slave timeout, (Check the baud rate, parity and the connectors on the slave.) And again with the ICHAR_GAP value of 1 it doesn't generate the error. It does interpret the answer only it takes about 8 seconds Witch is odd because im am monitoring the communication with a scopemeter and my Moxa uport with a serial port analyzer. They both indicate a interpretable answer in time frame of about 120ms
