GRAVIMETRIC GATEWAY AND ETHERNET COMMUNICATIONS

Below is a diagramed example of using Ethernet to break up a large serial network
Multi-branch Serial Network
– In the diagram above, a large serial network with an excess
of 30 blenders is broken into 4 branches. Branch 1, branch 2 and branch 3 are using an
Ethernet to Serial converter to convert Ethernet communications from the G2 Server to serial
using the G2-ES. The output of each G2-ES is then boosted using a signal amplifier (MLAN-
SA) and then out to the network of blenders.
Branch 4 is using the G2 Server’s own serial port and the G2-SA to communicate with that
group of blenders.
The primary reason for using a configuration such as this would be to improve troublesome
communications of a network of blender that is currently using a single COM port on the G2
Server through the G2-SA out to the entire network of blenders.
In the typical serial installation, approximately 25 blenders is the maximum that a single serial
network can handle without loss in communications. Some blender networks can handle
more blenders others less depending on factors such as distance, wire quality, electrical
interference.
The example above was used in a location where 68 blenders were in operation on a single
blenders serial network. By using the G2-ES the network could be split up into serial
networks with fewer than 20 blenders per branch. A side benefit to this configuration is
increased communications speed where the G2 Software could communicate with multiple
branches at one time.
