4.6.4 Configuring - first steps
The necessary settings are described that must be made or must be
observed when configuring the system. These will be described using an
example of a master-slave coupling (an EXM448-1 module is used as
master). An EXM448-2 module has two integrated SIMOLINK interfaces
that can be operated independently of one another. The SIMOLINK
communications is configured analog to EXM448-1 and is not separately
described.

Fig. 4-23 Example for a master-slave coupling
The SIMOLINK ring comprises the minimum of two and a maximum of
201 SLB modules, which are coupled to one another through fiber-optic
cables. There is only one SL master on a ring. All of the other nodes are
slaves.
An SLB module is a hardware component of an ITSL, an EXM 448-1
module or an option module SLB (SIMOLINK Board, Order No.
6SX7010-0FJ00). Two SLB interfaces (ports) are integrated on an
EXM448-2 module.
NOTE
Additional information on these modules and their installation is
provided in the User Manual D7-SYS “Hardware“, or SIMOVERT
MASTERDRIVES Instruction Manual SLB SIMOLINK board.
4.6.4.1 Configuring the SIMOLINK coupling under STEP 7
For SIMATIC FM 458-1 DP with EXM 448-1, the basic clock cycle T0,
possibly the interrupt task Ix and the symbolic hardware assignment for
the SIMOLINK are set in the HW Config of STEP7 in the properties
dialog box.
