FAQ

Question?
Can this DCO 01 module be used with a modern ABB 800xA or Freelance controller?

Answer

No, the DCO 01 is specifically designed for the obsolete Freelance 2000 system. It is not compatible with modern ABB control systems like System 800xA or the newer Freelance AC 900F controllers due to differences in architecture, bus systems, and software.

Question?
What is the function of the five D-Sub serial ports (Ser 1-5)?

Answer

These serial ports are used for communication with various field devices, third-party systems, or programming terminals. They typically support protocols like Modbus or other serial communication standards, allowing the Freelance 2000 system to integrate with a wide range of equipment.

Question?
What does the ‘F 6.01.1’ on the label signify, and is it important?

Answer

This indicates the firmware version 6.01.1 loaded onto the module. In legacy DCS systems, matching firmware versions between components can be critical for system stability and compatibility. When replacing a module, it is highly recommended to match the firmware version to avoid potential communication errors or system faults.
