Hi Davis, Thanks. It worked perfectly.!! I used function code 25; it is really useful. Almost direct interaction with ODSS. There is an observation though while using function code 25 in TCP. At first, I used the set command hoping that I could set the storage state and kw value updated in a single TCP write command as below: '25;002Cset storage.bessppc state=charging kw=-30000;' . But it did not work, as ODSS-G was showing unknown command 'kW' error. After that, I used edit command with function...

Hi Davis Sorry took long to reply to his message. There is a built in function with suitable library within codesys to perform TCP communication in localhost. We need to set the communication path in localhost in the codesys configuration window. Earlier, I was missing this step. Finally the communication is setup between codesys and ODSSG. However, I have run into an other issue while implementing the logic in codesys. I am writing the 'kW' value of storage element (BESS PPC in my case) from TCP...

Hi Team I am working on hybrid plant with PV, Wind and BESS in OpenDSS-G. The main script for controlling and implementing logic is being done on Codesys which is one of the standard coding platform used for industrial PLCs. Both codesys and ODSS-G are running on the same laptop. I am facing challenge with setting the TCP/IP connection with codesys with multiple error being shown (attached). However, if I open the TCP monitor in ODSS-G terminal, I do see some activity there (attached). Not sure what...

Thanks Davis. It worked in my PC. Appreciate your prompt support.

Hi OpenDSS Team, I have encountered a problem with setting up of system for simulation. I am trying to simulate a grid connected hybrid plant with solar, wind and BESS. I have defined minute wise load shape for solar and wind (both with multiplier array of 1440 values). BESS does not have any loadshape attached since I intend to control it via external program through COM port. While I was trying get the loadflow for testing the completeness of circuit definition, there is an error 303 reported with...
