Datalink's IPscada Software and Hardware
can provide a long distance communications link over satellite at a much
lower cost than conventional remote SCADA links which would normally use
VSAT dedicated service. IPscada puts an intelligent controller at the
remote site which only sends data when a reporting device drops out of a
pre-set operating window. This can reduce satellite airtime costs per
remote asset to typically under $50 USD per month. Data
processing hardware and satellite terminal cost is typically under $900
IPscada is a low cost satellite or terrestrial network communications link between
remote telemetry devices such as RTUs, PLCs and other remote sensors and base HMI control computers.
Functionally it acts as a transparent pipe, linking remote monitoring terminals and other devices for oil and
gas wells, pipelines, pumping stations, remote mining sites, compressor stations, reservoir storage tanks
and remote seismographs and the host HMI software. IPscada can support most protocols that use a TCP/IP connection on the host side and an asynchronous RS-232 serial
connection at the device. The link can use both terrestrial and satellite networks to provide regional and worldwide
coverage. The Technology has a designed in simplicity, making integration with existing legacy systems a

The third-party host software
connects to the DataGate server program using a TCP/IP socket. For
instant status polling sends a Modbus (or other protocol with addressing scheme)
packet to the server, which decodes the address field and uses a
look-up table to direct the packet to the appropriate
remote device. The server then communicates with the device
and waits for an acknowledgement. Any responses from the device are
sent back to the third-party host software using the same TCP/IP
socket. At this point the third-party software may close the socket,
or continue to exchange data.
For SCADA operation, third party Software should be OPC
For those host
software systems that are restricted to legacy PSTN "phone" dial-up
sessions, Datalink can provide a PSTN-to-IP internet interface
software module allowing full TCP/IP communications over any of the
integrated wireless networks.
Network Routing Interface
DataGATE acts as a “packet data”
router processing and routing packets between a number of host
computers connected to the Internet and the remote terminal devices
linked via satellite or terrestrial wireless services.
DataGATE software can be located at the
customers base offices or on Datalink's
Cloud Servers. Dual Mode communications is an
attractive feature providing the ability
to make use of very low cost VHF/UHF radios to link a number of well
heads within say 30 miles of each other and one central IPscada satellite
Automated data transfer.
Security encryption available.
Much lower satellite cost than Vsat and other “Circuit
Switched" satellite services.
Transparent Data transfer.
Multi-point data transmission.
Easy integration to existing IT infrastructure
Internet connectivity between PCs and the satellite ground
station provides virtually instantaneous data acquisition and
Many SCADA systems
are based on polling remote RTUs from the base software program
ever X seconds or minutes. This is not an issue when the link is
dedicated telephone lines, micro-wave or Vsat. However the cost
of linking to remote RTUs using the above options is often cost
overcome this problem by introducing intelligent monitoring at
the remote device. By issuing the appropriate commands to the
controller in the field , the MobiHUB i50 SCADA communicator can detect an anomaly in seconds
and will send an alert to the base HMI controller.
This eliminates the need for frequent polling and allows the use
of low cost satellite links on a global basis.
