Note
The number of servers supported is directly dependent on the maximum number of data points and is
therefore limited to 100 servers.
Example
There are 8 servers connected to the gateway; each with 10 data points. There are 80 data points in
total. The gateway could therefore support another 20 servers with one data point each. The limit is
specified by the number of data points.
Note
A repeater is required if you are installing more than 32 devices. This limit is specified by the Modbus
protocol.
