4.7.2 System requirements and restrictions for Flexi Link
For Flexi Link the following system requirements must be met as a minimum:
System component Version
Hardware WS0-CPU1 with firmware version V2.01.0 or higher, or WS0-CPU3
Software WS0-CPU1: Setting and Monitoring Tool version 1.3.0 or higher
WS0-CPU3: Setting and Monitoring Tool version 1.7.0 or higher
The Flexi Link system can be connected using only EFI1 or using both EFI1 and
EFI2. The overall number of status bits per station that can be made available to the
other stations in the Flexi Link system depends on the connection method.
Connection method Available status bits per station
EFI1 26
EFI1/2 52
 You can not use Flexi Link and EFI communication at the same time, i.e. it is not
possible to connect other EFI compatible devices on the EFI2 connection while
EFI1 is used for Flexi Link.
 The process data sent by any station are received almost simultaneously by all
other stations. The processing (logic) in the individual stations is, however, not
necessarily simultaneous, as the stations are not synchronized.
 The data on EFI1 and on EFI2 are consistent. The data on EFI1 and EFI2 can,
however, be inconsistent for a short time, as they are transferred separately.
4.7.3 Connection of a Flexi Link system
Do not use buffering elements in a Flexi Link system!
It is not allowed to use buffering elements such as e.g. CAN bridges, CAN repeaters
or CAN optical light barriers in a Flexi Link system. As a general rule, no components
other than Flexi Link stations are allowed. Otherwise the operator of the machine will
be in danger.
There are two possibilities for wiring a Flexi Link system:
 connection via EFI1 (26 bits)
 connection via EFI1 and EFI2 (52 bits)
Either way, always the identically named terminals have to be connected (e.g. EFI1 A
on station A with EFI1 A on station B etc.).
