Modicon M580 automation
platform
M580 backplanes
Presentation
The M580 PAC is complatible with two types of backplane: dual Ethernet and X-bus
backplanes or X-bus only backplanes (1)(2). One Ethernet switch is embedded in
the backplane with connectivity to some slots on the backplane (not all slots have
Ethernet connectivity).
X-bus functionality is preserved and conforms to the legacy implementation and
specication. The X-bus will be used in a subset of modules on the Ethernet
backplane.
The M580 backplanes provide power supply for all modules in the rack.
Function
The Ethernet backplane provides the following services to X-bus slots:
b provide rack number
b provide interconnection to all slots in main and expanded backplanes
The Ethernet interface is the main communication medium in the Ethernet
backplane. All Ethernet modules on the Ethernet backplane are attached to one of
several ports. The modules lead to the Ethernet switch chip embedded inside the
Ethernet backplane.
The Ethernet backplane provides the following services to ETH slots:
b provide ETH connection to ETH slots
b provide point-to-point lane connection
Description
Dual Ethernet and X-bus backplanes
The quantity of X-bus and Ethernet slots found on a backplane depends on the
backplane size.
BMEXBP0400/BMEXBP0800 are 4/8-slot dual Ethernet and X-bus backplanes
with:
1 CPS slot for power supply
2 4 slots (BMEXBP0400)/8 slots (BMEXBP0800) with:
2a 4/8 Ethernet and X-bus connectors for mixed modules
3 Expansion: 1 connector for an X-bus backplane expansion
4 2 xing points for the shielding connection bar
5 Protective earth screw
6 Slots for anchoring the module pin
7 Tapped holes for the locking screw on each module
8 4 holes for M4, M5, M6 or UNC #6-32 screws (4.32 to 6.35 mm/0.170 to 0.250 in.)
9 Rack is fastened to 35 mm/1.38 in. wide and 15 mm/0.59 in. deep DIN rails.
Mounting on a 35 mm/1.38 in. wide and 7.5 mm/0.295 in. deep DIN rail is possible
(in this case, the product withstands less mechanical stress)
BMEXBP1200 is a 12-slot dual Ethernet and X-bus backplane with:
1 CPS slot for power supply
2 12 slots with:
2a 8 Ethernet and X-bus connectors for mixed modules
2b 4 X-bus connectors for X-bus modules
3 Expansion: 1 connector for an X-bus backplane expansion
4 2 xing points for the shielding connection bar
5 Protective earth screw
6 Slots for anchoring the module pin
7 Tapped holes for the locking screw on each module
8 4 holes for M4, M5, M6 or UNC #6-32 screws (4.32 mm to 6.35 mm/0.170 to
0.250 in.)
X-bus backplanes (1)(2)
Available with 4, 6, 8, and 12 slots with BMXXBP0400/0600/0800/1200 for X-bus
modules.
