User Guide, Version 3.0

14.1.1

 

Features of Message Routing 

 
The 

Message Routing

 feature of the SATELLINE-EASy is designed to be a fast and transparent to 

fit real time systems. The features include: 

•

 

Transparent to user protocols. 

•

 

Easy construction of a network containing several repeaters. 

•

 

Any radio modem may operate as a repeater, i.e. dedicated repeaters are not usually 
needed thus cutting down on costs. 

•

 

Large areas of coverage may be implemented by using only one radio channel. 

•

 

The use of mobile substations is also possible to some extent. 

•

 

The system will be fully deterministic i.e. the transmission delays are predictable. Because 

of that, the principle of 

Message Routing

 is connectionless. 

•

 

Added redundancy, as a failing radio  modem can be, in certain cases, bypassed with 

another radio modem positioned in the same coverage area.  

•

 

Message Routing

  is intended mainly for the protocols based on polling scheme and a 

single master station. 

 

14.1.2

 

Limitations of Message Routing 

 

•

 

It is assumed that the position of the address field in the user messages is fixed. However 
some special protocols are supported: 

o

 

IEC 60870-5-101 is a protocol commonly used in control applications of power 
lines.  

o

 

RP570 protocol  

•

 

The message cannot end to the address; there must be at least one character after the 

address. 

•

 

It is assumed that there is only one message at a time inside the network simultaneous 

messages could cause collisions. 

•

 

The max number of the routes depends on the actual hardware and the Firmware 

version. 

•

 

Operation of the Tx / Rx addresses is automatically blocked in the case of switching the 

“Message Routing” function on. 

 

14.1.3

 

Getting started with Message Routing 

 
The design of any radio modem system requires very precise planning. Once the choices 
between devices, their location, installation, maintenance etc. are clear, the 

Message Routing

 

for the system can be implemented.  

 
Planning your Message Routing System 
1. Decide which mode of the 

Message Routing

 suits the system - 

Source Mode

 or 

Virtual Mode

. 

See the following paragraphs for details. 
2. Design a layout of the system describing the settings such as protocol, addresses of the 
terminal equipment, radio frequencies and so on.
