Functions of the stations in the network
The stations on the CL-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 CL-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 (
section “Send each change on the inputs/
outputs (SEND IO)”, page 327).
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 authorisations to the network bit data 2 to 8 SN 1 to 32.
Stations 2 to 8
Input/output device function
No write and read authorisation.
Intelligent station function
Authorised read access to all inputs and outputs of all
stations regardless of function. Note the SEND IO setting
(
section “Send each change on the inputs/outputs
Write authorisation to its own local outputs.
Write authorisations to the network bit data .. SN 1 to 32.

Station 1 must always have a circuit diagram.
