Independent Connections
Geo SCADA Expert allows you to use each network connection independently, which allows concurrent communication to send and receive data with multiple outstations, (see Scanning Process). The key points to consider when using the independent connections feature in Geo SCADA Expert are:
- available bandwidth on the network (particularly for IP radio based networks)
- number of IP devices on the network
- the network infrastructure (independent connections may not be suitable for radio or IP over serial networks).
When you use independent connections, Geo SCADA Expert can poll or interrogate multiple outstations on the network without waiting for the collection of data from each outstation in sequence.
Requests sent to outstations are currently processed sequentially and each request is dependent on the completion of the previous request.
system performance may be affected
When you select this option the server may experience a increase in the volume of data and this may affect the performance of the server. You should check the configuration of the channel and associated outstations in the system to ensure that the data that is required can be processed by the server.
The following configuration items may affect the amount of data that needs to be processed by the server:
