General Mach Discussion / Re: Need help with Mach3 Modbus to BRX PLC
« on: January 01, 2021, 06:47:44 PM »
I got Mach3 sending ethernet data to the PLC registers using the ModBus TCP test mode. What I want to send is just the S word, Spindle speed. Based on using Machscreen to view the displayed DRO value this should be OemDRO code 17. However I can’t seem to transmit the value of that code. The modbus tutorials all seem to be for serial.
Anyone point me in the right direction?
