  1. Hi Thanks Joe and Ausman for all your comments¡ I made test with your recommendations but there is no communication: The manufacturer sent to me an HMI, made by Weinview- WeinTek, configured to read the Holding Register and It works¡ My project is to use Unistream to read Holding Register as I said before. Then I made a reverse engineering downloading the configuration of that HMI and found that Addresses of Holding register are 6x, where x are 0 to 15. Check image of this. I am using modbus poll to try understand the problem. How can I read addresses like 6x? The Chinese manufacturer of HMI call to this config Modbus RT adjustable. Unitronics read Holding Registers 4x, modbus poll too. Comments, suggestions are welcome Thanks and Regards
  2. Hi Thanks for you kind answers ¡ I have tried with Modbus Poll but there is not communication¡ Timeout error. At the beggining of my application I test with a Tag Status generator UINT16 and Slave ID "1" but without communication. The manufacturer of device said that ID by default is 1¡ That ID is in a Holding Register, 40009. The master of application is the unistream, as I said before, but I think is not necesary to config an ID for it? or YES? Do I need to config the master with a ID? I want to stablish a basic communication reading a Only Holding register, 40001, and after the others. I show some pics of my config as attach I have appreciated all comments, thanks again.

Results of Test: Status of remote slave c. I change Status Generator UINT16 by an Array 16 (UINT16) Thanks again MGS
  4. Hi I have invested a lot of time without succes to comunicate a US7-B10-RA28(+ module UAC-CX-01RS4) with a ultrasonic device( modbus RS485 ). I want to read holding registers (40001 to 40016). The manufacturer of device recommend to read the holding register (03) ( 40001 to 40016), I did this with unilogic software but without succes¡ In Global Tags show: Modbus Slave Status: 3 Could help me ?
