Modicon X80 drop + expansion rack
Composition of an expansion backplane conguration
M580 CPU supports 4 to 8 local racks (depending upon the CPU performance
level), using existing X80 I/O modules and accessories. A Modicon M580 CPU must
be installed in the rst rack (#0) and this can be a dual bus rack. A Modicon M580
PLC will support up to 7 BMXXBPpppp PV02 or higher backplanes (racks) of 4, 6,
8, or 12 slots. The main backplane (rack #0) will support the CPU.
To expand the conguration using additional racks, users must use a bus expansion
module (BMXXBE1000) and X-bus cables. The backplane expander will be
plugged in the dedicated connector on the right side of the backplane. It will not
occupy any module slot. The XBE expansion module will not be hot-swappable in
accordance with Modicon X80. Each backplane has to include a power supply
module and will support up to 12 modules.
An expansion rack can be connected to the main backplane and the X80 drop
(EIO).
The rack address is assigned as follows:
b Each rack will be assigned a physical address using 4 micro switches located in
the bus expansion module.
b The main rack containing the CPU will be assigned address 0.
b The other racks will be assigned addresses 1 to 7.
Each rack is equipped with:
1 A BMXCPSppppp power supply
2 A BMXXBE1000 rack expansion module. This module, inserted in the right-hand
end of the rack (XBE slot) does not occupy rack slots 00…11 (4, 6, 8, or 12 slots are
still available).
3 The BMXXBE1000 rack expansion modules are connected to each other by
X-bus cordsets.
4 Line terminators: Both expansion modules at the ends of the daisy chain must
have a line terminator TSXTLYEX on the unused 9-way SUB-D connector.
Ethernet racks
The Modicon M580 CPU supports dual bus backplanes (Ethernet and X-bus), all
the processors support Ethernet ring or star architectures on their Ethernet port.
BMXP58pp2p processors support Ethernet star or ring architectures (RSTP loop is
supported on ports 2 and 3). The embedded scanner allows scanning of distributed
equipment. The CPU drives these devices directly (“NOC” embedded function).
BMXP58pp4p processors support an embedded scanner that allows scanning of
X80 drops on Ethernet RIO (EIO) in addition to distributed equipment.
M580 CPUs have an additional third Ethernet port dedicated to the connection of a
service tool such as a PC, HMI, or network analyzer. This port is labeled “ETH 1”. It
does not support RSTP.
M580 CPU will be able to communicate on the main Ethernet backplane. The
Modicon M580 CPU cannot be installed in an expansion rack.
It is necessary to use an Ethernet backplane
