Abstract: Through researching the selection for DCS operator station in industrial control system, the disadvantages of DCS operator station
based on UNIX platform are found in operation and maintenance. After investigating and analyzing current status of use for DCS operator station,
two types of DCS operator stations based on UNIX and Windows NT(2000) were compared. It was found that the problems in security and
stability could be resolved by using DCS operator station based on Windows NT(2000)，and concrete measures for improving were proposed.
The practice proves the DCS operator station based on Windows NT(2000) is provided with low costs and features strong open characteristic. It
is the developing trend of DCS operator station in future.
