Architecture A
Presentation
Architecture A is used for control systems that reside in the main control cabinet.
The M580 platform provides interrupt services for this type of application.
Up to 94 slots are possible for I/O modules in a conguration comprising a main rack
and 7 expansion racks, connected by BMXXBEp00p 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 A can comprise a maximum of 10 I/O modules in the main rack, in
addition to the CPU module 2 and the power supply module 1.
These local I/O can be extended on an expansion rack by using a BMXXBEp00p
rack expansion module 3.
Ethernet slots are available only in the main rack because rack expansion cables
only support X-bus.
The choice of appropriate rack depends on the required number of modules for the
system. Main racks are available in the following formats: 4, 8 and 12 slots.
As well as discrete and analog I/O modules, the following modules are available:
b Application-specic modules:
v SSI encoder
v Counter
v Pulse train output
v Weighing
Some application-specic modules (weighing, etc.) require use of an Ethernet
backplane.
If necessary, communication and network modules can be installed in the local rack.
The majority of communication and network modules need to be in the local rack.
Architecture A conguration rules
When conguring an architecture A system, the following four parameters should be
considered:
b Number of slots available in the 8 local racks (main and expansion racks)
b Slots available for optional modules
b Power consumed by the installed modules
b Addressing words available for conguring the modules
Available slots and power consumption
Architecture A can have a maximum of 94 available slots (with eight 12-slot racks)
for I/O modules, application-specic modules and communication modules.
These modules are powered from the power supply included in the rack.
For a valid conguration, 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 (1)
With Unity Pro, the I/O addressing is unlimited (physical limitation: 94 slots).
(1) Requires Unity Pro software V8.0.
