Modbus / Re: Modbus Spindle Help
« on: January 04, 2015, 06:18:22 PM »
Thanks for posting the screen shots, I went through and compared them to my setup and they are identical except that I am using a RS485 to serial adapter instead of a second parallel port. Perhaps that is where my configuration problems lie. Maybe Mach3 is finicky about what RS485 converter it will talk to. I used a serial port sniffer to monitor all COM1 traffic and found that Mach3 was opening the port and trying to communicate but never getting a reply. Sometimes the port testers would work, sometimes they wouldn't--could just be a glitch related to all the opening and closing of the port I was doing:
Very strange that the VFD doesn't respond when Mach3 is talking. Maybe the timing of the messages is off? All the programs are configured for 9600/8N1.
