6-6 Pico-Link and Point-to-Point Serial Connections

Functions of the Stations in the Network

The stations on the Pico-Link 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 on the Pico-Link

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. See Send Each Change on the

Inputs/Outputs (SEND IO) on page 6-9.

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. See Send Each Change on the

Inputs/Outputs (SEND IO) on page 6-9.

Write authorization to its own local outputs.

Write authorization to the network bit data SN 1 to 32.

IMPORTANT

Station 1 must always have a circuit diagram.
