458 Practical Modern SCADA Protocols: DNP3, 60870.5 and Related Systems
Procedure and observations
• Use the Citect screen to verify that the outputs can be turned on and off.
• Verify that the inputs are operating correctly.
• Note that the analog inputs show values.
Additional exercise:
If time permits, set up the diagnostic display of RTU and use this to observe traffic on the
network.
PRACTICAL SESSION 6
TOPIC: RADIO PATH DESIGN PROBLEM
Overview
It is necessary to consider all the issues from designing the radio system to configuring
the DNP protocol when setting up a complete system. In this exercise we use a radio path
design program to design a radio link.
Equipment required
Procedure
• Notebook computer
• Teledesign software program
Master site
Site A – to co-ordinate the pumping of water from the 5 RTUs; each at an approximate
distance of 40 km away from the master site.
Five RTU’s sites – Boreholes with tanks next to them to temporarily store
the water before pumping it to the master site.
Site B Borehole
Site C Borehole
Site D Borehole
Site E Borehole
Site F Borehole
The path between Site A and Site B has the following profile.
0 km 220 m Flat Dry
5 km 150 m Flat Dry
10 km 120 m Flat Dry
15 km 120 m Flat Dry
20 km 130 m Flat Dry
25 km 130 m Flat Dry
30 km 110 m Flat Dry
35 km 120 m Flat Dry
40 km 150 m Flat Dry
