Functions of the stations in the network
The stations on the EZ-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 authorization in the network
The stations have differing read and write authorization in the
EZ-NET network according to their functions and
configuration.
Station 1
Authorized read access to all inputs and outputs of all stations
regardless of the function. Observe the setting of SEND IO
Section “Send each change on the inputs/outputs (SEND
IO)”, Page 341).
Authorized write access to the station's own local outputs.
Authorized write access to the physical digital outputs of the
stations which are functioning as input/output devices.
Write authorization to the network bit data 2 to 8 SN 1 to 32.
Stations 2 to 8
Input/output device function
No read and write authorization.
Intelligent station function
Authorized read access to all inputs and outputs of all stations
regardless of the function. Observe the setting of SEND IO
Section “Send each change on the inputs/outputs (SEND
IO)”, Page 341).
Write authorization to its own local outputs.
Write authorization to the network bit data SN 1 to 32.

Station 1 must always have a circuit diagram.
