H2-ECOM100 LED Indicators
H2-ECOM100 Network Identifiers
Each module must be assigned at least one unique identifier to make it possible for other devices
to recognize it on the network. There are four identifiers possible with the ECOM modules:
• Module ID
• Name
• IP (Internet Protocol) Address
• Ethernet (MAC) Address
The first three are user selectable but the MAC address is set at the factory. The type of identifier
chosen depends on the requirements of your particular application. PC-to-PLC communication
typically uses one type of identifier while PLC-to-PLC communication may require another. The
following table summarizes Network Identifiers and their uses:
