Functions of the stations in the network
The stations on the easy-NET can have two different
functions:
• Intelligent stations with their own programs (stations 1 to 8)
• Input/output devices (REMOTE IO) without their own
program (stations 2 to 8)
Possible write and read authorisation in the network
The stations have differing read and write authorisation in
the easy-NET network according to their functions and
configuration.
Station 1
Authorised read access to all inputs and outputs of all
stations regardless of the function. Observe the setting of
SEND IO (a Section “Send each change on the inputs/
outputs (SEND IO)”, Page 255).
Authorised write access to the station's own local outputs.
Authorised write access to the physical digital outputs of the
stations which are functioning as input/output devices.
Write authorisation to the network bit data 2 to 8 – SN 1 to
32.
Stations 2 to 8
Input/output device function
No read and write authorisation.
Intelligent station function
Authorised read access to all inputs and outputs of all
stations regardless of the function. Observe the setting of
SEND IO (a Section “Send each change on the inputs/
outputs (SEND IO)”, Page 255).
Write authorisation to its own local outputs.
Write authorisation to the network bit data SN 1 to 32.
