Important DH-485 Network Planning Considerations
Carefully plan your network configuration before installing any
hardware. Listed below are some of the factors that can affect system
performance:
• amount of electrical noise, temperature, and humidity in the
network environment
• number of devices on the network
• connection and grounding quality in installation
• amount of communication traffic on the network
• type of process being controlled
• network configuration
The major hardware and software issues you need to resolve before
installing a network are discussed in the following sections.
