Hello, I've recently acquired the UCR-ST-B8 router from Unitronics. The set-up was easy but it won't communicate with other devices. My goal is that the router is connected to a PLC through a direct ethernet cable and that the PLC can read the status of the router, effectivly making the router a slave of the PLC. I also want to recieve SMS messages on the router and the PLC to read those messages. *Note I did change the IP from 192.168.1.1 to 192.168.0.1 With a cable in LAN 1 of the router and the other end in a laptop we can connect to the webUI. Here (Services-->Modbus) I've configured the router as a modbusTCP slave and did save the settings. After this I close the webUI and connect to the router using QModMaster (https://sourceforge.net/projects/qmodmaster/). With this program I should be able to read the registers of the router. (I know this works as I've used it before) But when I try to read the registers it doesn't get a return signal. After this I've tried it using a PLC. But I am not really familliar with the Unilogic enviroment so I'm having a bit of trouble setting it up. As stated earlyer I want to read the data from the router and recieve SMS messages from the router and read those using the PLC. Would I need to setup the router as a router or as a modem in the Unilogic enviroment? Further if I set it up as a router would I need to take extra steps to read out the UCR-ST-B8 or should I be able to read all the data immediately? So the questions I have are: How do I read out the router? What settings need to be configured. Is it possible to read the data using a PLC? I'm using a USC-B5-T24 and how would I do that. Should I use ModbusTCP or Modbus RTU rs485?
Hello, I'm trying to use V700 as master and two lexium mdrive motors as clients through MODBUS/TCP. I set up the function blocks per example "V700_Modbus_TCP_master.vlp". I can get the motors to connect with V700 but once i write modbus commands to motors i get no motion. one of the examaples for requesting commad is mentioned below as modbus tcp commad for the motor to move at slew speed of 600000 micrsteps/sec. Please take a look at the code and let me know what i'm doing wrong. Also please let me know if you need more information. Thank you in advance for the response. Vertical Sandblaster.vlp
Hello, Whe are working on a project to use the V570 within a self service bays carwash. This is working great! But now whe wanne go a step further with this project. But whe dont have the knowledge to implementate a Modbus to the V570 to read and write data to it. So my question is of anyone have a working modbus/TCP example? So i can connect to the V570 to read and write data over this connection. Thank you!
