Configuration of the Flexi Line logic

The logic for a Flexi Line station is programmed in 2 steps:
 Integration of the local data for the station into the Flexi Line process image: All
local information of relevance for the Flexi Line process image must be integrated
into the process image with the aid of a Routing function block.
 Creation of the local logic with the aid of the process image data.
Example of simple Flexi Line logic
The following example shows a station with an emergency stop pushbutton and a
reset pushbutton. This station switches a machine via a single-channel safety output.
The following figure shows the hardware configuration:
The station is connected via Flexi Line to identical or similarly configured stations on
which the states of the two buttons should also be available. For this purpose two
bits are used in the process image:
 Bit 1: global byte, default value: high, name: E-stop
This bit collects all emergency stop commands from all stations: If an emergency
stop pushbutton is actuated on any station, this bit is set to low (logical AND).
 Bit 9: global bit, default value: low, name: Reset
This bit collects all the reset commands from all stations: If a reset pushbutton is
actuated on any station, this bit is set to high (logical OR).
The signals from the two pushbuttons connected are now routed to the Flexi Line
process image:
