ECOM Network Identifiers
This section describes network identifiers that can be assigned to the ECOM module. Each
module must be assigned at least one unique identifier to make it possible for PCs or other
ECOMs to recognize it on the network. Four methods of identifying the ECOM module give
it the flexibility to fit most networking schemes.
The four ECOM identifiers are:
• Module ID
• Name
• IP (Internet Protocol) Address
• Ethernet (MAC) Address
The first three are user-selectable. The last one is set at the factory. Each of the identifiers is
discussed in this chapter. If you have more than a few ECOMs on your network, consider
making a chart or spreadsheet of network IDs, as shown below:
The decision about which type of identifier to use is an important one. Much of the decision
depends on the requirements of your particular application. PC-to-PLC communications are
generally better accommodated with one type of identifier while PLC-to-PLC communications
require a different type. Ease of maintenance and troubleshooting also must be considered
before deciding which type to use.
The identifiers are used to link your PC to your PLC or one PLC to another PLC. The flexible
design of the module allows you to use different identifiers for different links to the same
module. This is particularly important if you require both PC-to-PLC and PLC-to-PLC
communications on the same network.
The following table summarizes Network Identifiers and their uses:
