These design sheets are provided as examples. PLC vendors often supply similar
sheets. Many companies also have their own internal design documentation procedures. If
you are in a company without standardized design formats, you should consider implementing
such a system.
32.6 COMMISIONING
When a new machine is being prepared for production, or has been delivered by a
supplier, it is normal to go through a set of commissioning procedures. Some typical steps
are listed below.
1. Visual inspection
• verify that the machine meets internal and external safety codes
- electrical codes
- worker safety codes (e.g., OSHA)
• determine if all components are present
2. Mechanical installation
• physically located the machine
• connect to adjacent machines
• connect water, air and other required services
3. Electrical installation
• connect grounds and power
• high potential and ground fault tests
• verify sensor inputs to the PLC
4. Functional tests
• start the machine and test the emergency stops
• test for basic functionality
5. Process verification
• run the machine and make adjustments to produce product
• collect process capability data
• determine required maintenance procedures
6. Contract/specification verification
• review the contact requirements and check off individually on each one
• review the specification requirements and check off each one individually
• request that any non-compliant requirements are corrected
7. Put into production
• start the process in the production environment and begin normal use
