Lỗi “Failed to initialize the COM library module” trong phần mềm CICON
Q: How to solve an issue when you cannot connect to CICON via USB, Serial and Ethernet ports and get an error message.
“Failed to initialize the COM library module.
Please check whether the port was already occupied by other program.”
A: This error occurs when the following four COM library module files are not properly registered on your PC due to the absence of “Microsoft Visual C++ 2008 Redistributable Package (x86).”
-When you cannot make a connection between CIMON PLC and CICON software via USB, Serial and Ethernet ports, you need to check on three things:
+ Did you install “Microsoft Visual C++ 2008 Redistributable Package (x86)?
+ Is USB driver for CICON or Serial driver recognized in Device Manager?
+ Did you change the location or name of the CICON installation folder?
– CICON software has been built on Visual C++ 2008 and 32-Bit. No other versions are acceptable except the “Microsoft Visual C++ 2008 Redistributable Package (x86).
Please download the package directly from Microsoft
-If properly installed, CIMON PLC USB driver should be recognized in Device Manager.
+ 64bit: CIMON PLC USB Driver for CICON
+ 32bit: KDTUsbDRv
– Also, check your Serial Port (COM) number in Device Manager for serial connection.
– Once the CICON installation location is fixed at the below photo, the location andn ame of the installation folder must not be changed after the installation.
+ For instance, the location has been decided to be “C\CIMON\CICON”
+ Do not move the location of the installation folder to somewhere else.
+ i.e. Local Disk (D:) → SOFTWARE → CICON → CICON6.00 En_20150701
