2-2.2 Control Stations (ICS) and DynaLite Gateway (IG02)
Control Stations and DynaLite Gateways connect to the Global network and do not connect to the Net
network. This will present a few variations in how these devices could be connected to the network.
It is important to ensure that the screen is kept continuous.
This style of connection applies to all globally connected devices.
The rules of application are similar to that of the HMI or Converter connections in the prior section.
You must ensure the global and net cable lengths are the same.
In this correct example you can see that the GLB comms screen is in ‘S1’ terminal only. If you were to
use the ‘S1’ and ‘S2’ terminals you would break the continuity of the GLB screen. This could cause a
potential difference between each side of the ICS / IG02 and possibly introduce network reliability
issues.
The ICS / IG02 must have the earth terminal or the 24V neutral, connected to earth where available.
This will provide the path for the soft earth.
