Installation
If multiple INFORMA PMD-A devices are installed at a given location or across different
locations, they communicate with each other using twisted pair or fiber-optic Ethernet as
shown in the following figure.
Figure 4.2 – Networked INFORMA PMD-A
In Figure 4.2, INFORMA PMD-A #1 is configured as the time master and INFORMA PMD-A
#2, #3, and #4 are configured as time slaves.
Note
•
The twisted pair Ethernet communications are also known as
10/100 Base-T, and have a maximum range of 100 m (300 ft)
under normal conditions for error free communication. It is not
recommended that the user extend twisted pair Ethernet cables
beyond an adjacent cubicle in a substation environment. This is
done to avoid induced transients from other conductors.
•
Fiber-optic Ethernet network, also known as 100Base-FX, is
recommended for long distance communication that can be
extended over 1 km, when being used in multi-mode fiber.
