[Unitronics 1 UCR-ST-B8 Router wired connection modbus tcp]

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?

 

 

 

 

["Sticky" SB217 - SD Card Present]

Hi, I came across the same problem. I am also using an extension cable.

I found that if  I use the "SD safely remove" function block, SB217 will reset when the SD card is removed from the extension cable.
