Re: C++ code for Modbus used with AZ series

Ok, I think i solved it. The problem for this very error was: the char delay in the serial console was set to 4ms. Apparently that was too long for the drive and it timed out in between the frames...After changing it to 1ms I got a valid response and the LED stayed green.

Re: C++ code for Modbus used with AZ series

When I connect a slave simulator on my laptop as a second slave to the network it also recognizes the message without a problem.
Sorry for the posts but I couldn't figure out how to edit them.

Re: C++ code for Modbus used with AZ series

According to the AZ function edition this means: Stop bit 0 was detected. The funny thing is: I connected another RS485 to USB converter to the second ethernet port of the driver and connected that converter back to the controller PC. When I open a serial terminal on the new COM port and monitor wha...

Further infos from MEXE:
In the communication monitor it says "framing error" after I tried to send a command from the master to the slave.

Re: C++ code for Modbus used with AZ series

I just connected the drive to MEXE02 and found the alarm record. Before I reset it it was filled with errors of the one in the screen shot I attached. Maybe that helps you in diagnosing my problem. Thank you.

Re: C++ code for Modbus used with AZ series

Hi, thank you for your reply. Meanwhile I have been able to get the open source libmodbus library to work so i can now send hex commands from my computer through the Digitus DA-70157 USB to RS485 converter to the stage driver.

We would like to integrate the communication with the stages into our C++ script of the overall process in which we are using them. Since we don't have any experience with ...
