[AnandHegden]

Hi, Please could I know the reason for getting error code 1873 while registering the variable in TwinCAT 3.1 PLC. and what is the possible way to solve the issue?

Could you provide more context? What API do you use? Is this happening when using TcOpen? What is the target system?

[AnandHegden]

Using TcAdsDll.dll API , while we register the variable using TwinCAT ADS Communication and target system is Win 10 with MFC C++ windows Application
