I have a controller 750-8208 with programming software codesys v2.3.9.66. I want to read modbus tcp data through FB. When I load the library i.e. ModbusEthernet_04.lib, the program shows error. Is there a way to upgrade this library in codesys 2.3 or is there any other library through which i can read data.
I believe you need to add the Ethernet.lib library to your project. On my system, that library is found in the “32-Bit” folder inside my 2.3 library repository.
yes issue resolved thankyou.
