Power Supply Errors
A system can be stopped entirely if a power supply error occurs. When you
want to avoid the full system stop to assure the system security, you may
consider providing several power supplies in a network, and group the Slave
Units with individual power supplies.
Cost Considerations
Total cost and other elements as in below must also be included in the
consideration of power supply method.
• Capacity and the number of pour supply units,
• Cable thickness (or allowable current), and length (or voltage drop),
• System safety, and
• Wiring manhours
