Pr00 = 03 (Frequency control via RS485).We set the communication parameters as follows:

In addition to the basic parameters set by the motor (Frequency, Current, Voltage). The RS485 communication port of the VFD-M is an RJ-11 port (you can get a desk phone jack) DELTA VFD-M Communication Setting To be able to do this we need the software “Modbus Poll” and “USB to RS485 Cable” Wiring Diagram Today I would like to continue to guide you to use a PC to control the inverter directly. or 40001+1024(%QW- outputs)+20 = 41045- for me this makes the most sense, give or take 1 depending on whether we count the zerosĪlso, I will definitely try ScadaBR, I was just wondering if AdvancedHMI will work as well, because my coworker likes it.Hello everyone! In many previous posts, has guided you to use different HMI/PLC to control Delta VFD-M inverter using Modbus-RTU RS485 communication standard. 40021 (as per the standard Modbus numbering, if we start from 40001) Say, if I want to use the 16-bit holding register number 20, will I have refer to it as: My main question would be, in the HMI application how would we refer to a certain holding register? Same thing applies if we try to manipulate the Modbus register fromĪnother utility while trying to troubleshoot. It really does not simpler than that, I know but I am just testing In an OpenPLC program and will cause the program to turn on or off certain outputs on the GPIO. The holding register variable will be referenced The HMI will control a holding register variable. %QX1.2 (for the output directly) or %MW500 or something else along those lines? Appendix 1 Modbus address table of Delta DVP series PLC. Do we use a number (such as 40010, according to the number of the register) or Connected to MB device Delta HMI Modbus Read Discrete Input Registers failed on MB device Delta. Variable that controls something in the PLC program. Let's say if you want to assign a button on the HMI to a Modbus register, which controls a The choices that AHMI offers are Modbus TCP and RTU among a number of other driversĢ) What is the correct way to reference the Modbus registers? To connect to the GPIO if we want to interface with it from another application? Would weĬhoose Modbus TCP? If yes, then will the IP address of the Raspberry be the same that it has Would someone else be kind enough to direct me where to look for answers to theġ) I am aware that OpenPLC runs as a Modbus slave. However, the interfacing between openPLC and AvancedHMI is I can also run the Advanced HMI application on the Raspberry itself (I have aħ" screen). Inputs and outputs changing state controlled by the PLC program. So far I can run the openPLC package on the Raspberry and see the GPIO Run both a PLC program and an HMI application.
