if i use an evaluation license, can i create configurations for the plc freely?
Yes you have full functionality of Automation Studio with the Evaluation License for testing purpose.
But be aware that for commercial usage you need to buy a proper license. Make sure to contact your local B&R sales contact if you have more specific questions regarding licenses and regulations.

because i am currently using an evaluation license, when i configuring the program to be added to the PLC, when i was sending the program something happened to my PLC, the RDY/F indicator light turned red and an error accurred
In case of error you have to check the logger of the CPU
this would be not problem of AS evaluation license. Check state of PLC (SERV?) and logger using AS or SDM 
Note: I have created new topic, discussion here is interesting but has no relation to previous topic (problem with evaluation license registration)
where can i do cpu logger?
It turns out I got an error like that after I plugged the memory card into my PLC, immediately my PLC was not detected on my computer but the indicator light on the ETH was on
Hi,
the PLC can only be found by online browsing, if SNMP is set at least to âread-onlyâ at the ethernet interface.
In actual versions of Automation Studio / Runtime, this functions is deactived by default because of cyber security reasons.
To activate it, go to the settings of the ethernet interface, change the setting at âSNMP parametersâ, and transfer the changes to the PLC (online or by creating the CF card offline)
Best regards!

Do you know the IP address, is it set manually?
If yes, does a ping to the IP address delivers a response?
yes i know, i set it manually and it is connected to eth
Ok, can you open the SDM by using a browser and adding âhttp:///sdmâ?
I just saw in your screenshot, that youâre using a IP address out of the public IP range - is that right / really wanted?
Because in almost all common network setups, normally you should use an IP address out of the private IP range â using a public one would lead to problems (for example, the router of your network would try to route the communication out to the internet instead of locally trying to connect to the PLC).
maybe for now itâs just making and doing exercises, maybe later I will reset the IP, because at the moment I still often encounter lots of problems
because at this time my plc can no longer connect to the pc
If the setting of the IP address and subnet mask does not match to the setup of the network on your development machine with Automation Studio, then you wonât get online at all.
So I only can recommend again to check your IP settings inside the project, and if they match to your network settings of the notebook with Automation Studio - the part of the IP address that I can see in the screenshot looks really strange to me to be honest.
Whatâs the IP address and subnet mask of your notebook?
but this problem only appears when I insert a memory card, without a memory card my PLC will be detected
Hi,
yes, thatâs normal.
If you donât have inserted a CF card, the so called BootAR (AR = Automation Runtime, the operating system) is started.
The BootAR is a minimized version of the operating system stored in a hardware mounted memory of the PLC. The only functionality of BootAR is to boot a PLC into a state where a online communication is possible to do an initial commissioning of the PLC (to transfer the full-featured AR + a project to a empty CF card)⌠so, the BootAR is something like the âBIOS of the PLCâ.
With BootAR, SNMP and the DHCP client on the ethernet interface are automatically active.
As soon as a AR + project data is stored on the CF, the PLC boots the AR from CF and all the settings, programs and so on from the project are active.
Best regards!
What I can see from the picture is, that the PLC is in error (at least it looks like since the R/E Led seems to be solid red).
For testing purpose, I would recommend to start an epty test project from scratch:
- make a new project with the suitable PLC
- set SNMP to activated
- set a suitable IP address and subnet mask that is out of the IP network range of your development notebook
- donât add any more hardware modules in this test project, nor any programs or other software components.
- prepare the CF with an offline Installation using a CF card reader and your development notebook.
- boot the PLC with this minimal setup and check if the PLC boots into RUN (R/E Led solid green, RDY/F off, S/E solid green)⌠This will take some time after a offline Installation, and the PLC will automatically do 2 reboots while Installation is running.
If everything runs as expected, the PLC should be online accessible after the initial Installation.
Best regards!
