4 TIPS FOR DCS SPARE PARTS MANAGEMENT

In the use of the DCS control system, its management work is more important. General DCS spare parts management requirements are summarized in four aspects: storage, inspection, use preparation, and use.

 

 

1.Storage

 

DCS system, spare module storage requirements should be met: all kinds of modules must be packaged in anti-static bags after storage or according to the requirements of the manufacturer, the temperature and humidity of the module storage room should also meet the requirements of the manufacturer; Anti-static measures should be taken when accessing the module. It is forbidden to touch the circuit board by hand at any time, and to register and handle the procedures for entering and leaving the warehouse.

2.Regular Inspection

 

Every six months, all kinds of commonly used DCS spare parts are inspected. Of course, the cycle set by different companies is different, depending on the actual situation. The inspection contents are as follows:

 

The surface is clean, the printing plate insert has no oil stains, the printing plate insert has no oil stains, and there is no abnormality after a slight tapping.

 

 

Load the test software and work normally for no less than 48h;

 

Switching test of redundant modules;

 

The software loading and unloading test is normal, and the communication port and the hand station are working normally;

 

Various analog, digital input and output channels work normally;

 

After the inspection, the inspection record should be filled in and the qualified mark should be attached.

3.Preparation Before Use

 

Before running, you must check whether the communication port, I/O function and control algorithm function meet the requirements; check the module status on the engineering station to meet the requirements; load the configuration in the module and check if it is correct.

 

 

4.Usage Record

In actual use, the module address and other switches should be set. After confirming the relevant personnel, the correct mold position can be inserted and the record card can be filled out.

 

The above is a summary of the four key points in the management process of DCS spare parts. According to different use industries and environments, the content can be improved and suitable for different occasions.
