Hi everyone! I just need some help regarding on a project I'm working on. The idea of my setup is I have an Omron NS8 HMI connected to Mitsubishi inverter (FR-D700) through Modbus RTU Protocol without any PLC (is this possible?). The master is HMI and the slave is inverter. I use this so that I'll just input a running frequency to the HMI and the HMI will write it to the frequency. I have completed the setup, wiring and parameter setting on the inverter. Here is the problem, when I created a screen and transfer it to HMI and run some test, there is no reaction on the inverter and I just can't even make it run. On the screen, I created a Button for run signal with address "INVERTER:400009.02". Is there something wrong with my address or setting that I miss perhaps. Any help or tips regarding this. Thank you in advance.
