Architecture B
Presentation
Architecture B is based on architecture A with the possibility of adding eldbuses
such as AS-Interface, Modbus SL, HART, etc.
Architecture B is used for control systems that are wired to the main control cabinet.
It consists of a mainly local topology with several peripherals distributed over
eldbuses.
The Modicon M580 automation platform provides interrupt services for this type of
application.
Up to 94 slots are possible for I/O and communication modules in a conguration
comprising a main rack and 7 expansion racks, connected by BMXXBE
p00p rack
expansion modules.
Description
The Modicon M580 automation platform provides local I/O management for control
systems that are wired to the main control cabinet.
Architecture B can comprise a maximum of 10 I/O and communication modules in
the main BMEXBPpp00 rack, in addition to the CPU module 2 and the power supply
module 1. These local I/O and communication modules can be extended on
expansion racks by using a BMXXBEp00p rack expansion module.
The choice of appropriate racks depends on the required number of modules for the
system. Main racks are available in the following formats: 4, 8 and 12 slots.
If necessary, communication and network modules can be installed in the main
rack. The majority of communication and network modules need to be in the main
rack.
As well as discrete and analog I/O modules, the following modules are available:
b Communication modules:
v Serial link 3
v AS-Interface 4
v HART 5
Some communication modules (Modbus/TCP and EtherNet/IP network module,
HART analog I/O modules, etc.) require use of an Ethernet backplane.
Architecture B conguration rules
When conguring an architecture B system, the following four parameters should
be considered:
b Number of slots available in the 8 local racks
b Slots available for optional modules
b Power consumed by the installed modules
b Addressing words available for conguring the modules
Available slots and power consumption
Architecture B can have a maximum of 94 available slots (with eight 12-slot racks)
for I/O modules, application-specic modules and communication modules.
These modules are powered from the power supply included in the rack.
For a valid conguration, simply add together the consumption (in mA) of the
modules in the rack and check that the total current is less than that provided by the
selected power supply.
This power consumption calculation can easily be performed using Unity Pro
software.
Empty BMXXEM010 modules are also available to occupy unused slots.
Module addressing
With Unity Pro (1), the I/O addressing is unlimited (physical limitation: 94 slots).
(1) Requires Unity Pro version ≥ 8.0 software.
