Hi everyone, I’m not a “MODBUS” person so please bear with me. I have a serial device with data in registers 1 and 2 that I need to read. When I navigate to
ALEOS RV50X (4.13.0.017) /Serial/RS232 Configuration/MODBUS/General option I’m presented with Address Entry of “0=:0” which I don’t understand. I’ve entered “1” and “000001” as the address that I need to read and both have failed with an Error. I cannot find a place in the documentation that explains what this is expecting.
In ACEmanager, go to Serial > RS232 Configuration > MODBUS.
Under Address List, click Add More.
Enter the Index number, an equal sign, and the IP address. For example:
10=123.123.123.123 (decimal)
0xA=123.123.123.123 (hex) Prefix 0x to hex numbers.
Note: The range for index numbers is 0–255 (decimal) or 0x0–0xFF (hex). The Modbus address list accepts up to 100 entries. Including the port number after the IP address is optional. If you include the port number, separate the port number and IP address by a colon.
For example:
10=123.123.123.123:11223
0xA=123.123.123.123:11223
Please refer to page 311 in the AirLink RV50/RV50X Software Configuration Guide for more details.
Thanks, so I added my modbus register and my ip like 1=198.178.xxx.xxx:80 to the unit but it’s not report or sending any data, any other ideas that might help.
Yes, I’m curious what is the RV50 sending to the IP Address? it is a post request to that server ip? Is there something special required to communicate?
I’m having issues with this same seutp. I have my Sierra Wireless RV50X:
Port 502 Forwarded to Gateway’s LAN
RS232 = Port Enabled
Startup Mode Default = Modbus RTU (Binary)
Address List = (5=MyServerAddress:502)
Server producing Modbus TCP communication:
Sierra Wireless WAN Address:502
Reading 6 Words starting at 40002
I’ve verified that my PLC RS232 port is configured correctly at 19200 8N1 and modbus Address is 5.
I’ve swtiched both RX and TX around.
I’ve been battling this all day yesterday, I’ve setup a couple different manufacturers gateways pushsing a Modbus TCP comm out a Serial Port and they will just work, this gateway has been the opposite, no matter how I set it up it just wont communicate with a Modbus RTU device?
