Addressing at SPEED-Bus
To provide specific addressing of the installed peripheral modules, certain
addresses must be allocated in the CPU.
With no hardware configuration present, the CPU assigns automatically
peripheral I/O addresses during boot procedure depending on the plug-in
location amongst others also for plugged modules at the SPEED-Bus.
In the hardware configurator from Siemens up to 8 modules per row may be
parameterized. At deployment of SPEED7 CPUs up to 32 modules at the
standard bus and 10 further modules at the SPEED-Bus may be controlled.
CPs and DP masters that are additionally virtual configured at the standard
bus are taken into the sum of 32 modules at the standard bus.
For the project engineering of more than 8 modules you may use virtual
line interface connections. For this you set in the hardware configurator the
module IM 360 from the hardware catalog to slot 3 of your 1. profile rail.
Now you may extend your system with up to 3 profile rails by starting each
with an IM 361 from Siemens at slot 3.
You may access the modules with read res. write accesses to the
peripheral bytes or the process image.
To define addresses a hardware configuration via a virtual Profibus system
by including the SPEEDBUS.GSD may be used. For this, click on the
properties of the according module and set the wanted address.
If you do not like to use a hardware configuration, an automatic addressing
comes into force.
At the automatic address allocation DIOs are mapped depending on the
slot location with a distance of 4byte and AIOs, FMs, CPs with a distance
of 256byte.
Depending on the slot location the start address from where on the
according module is stored in the address range is calculated with the
following formulas:
DIOs:
Start address = 4
⋅
(slot -101)+128
AIOs, FMs, CPs:
Start address = 256
⋅
(slot -101)+2048
