The Honeywell maintenance of the PKS system can be roughly divided into three aspects: daily maintenance, preventive maintenance, and fault maintenance. Daily maintenance and preventive maintenance are maintenance performed before the system fails. The fault maintenance is maintenance after the occurrence of a fault, which has already caused a certain impact on the DCS itself or production at this time, in order to avoid the occurrence of similar faults.

Routine maintenance is the basis for maintaining and improving the stability and efficient operation of the system. mainly includes:

1) Establish and perfect system maintenance and management system to ensure that the temperature and humidity in the control room are within the normal range.

2) Avoid all electromagnetic field interference to the system work, and do not easily move various cables and network lines.

3) Pay attention to keep the control room, cabinet room, and engineer station clean and cool.

4) On-time inspection of redundant equipment such as controllers, FTE networks, servers, etc., and make inspection records.

5) Do a good job of backing up system configuration files and system data files.
