Local Rack Modules
Each local rack, the primary and the standby, in an M580 Hot Standby system includes the following equipment:
Both the primary and standby local rack may also include:
NOTE: An M580 Hot Standby local rack:
  • Does not support I/O modules.
  • Does not support serial communication modules.
  • Cannot be extended.

1. The BMEH586040 CPU supports the sum of program and data up to the stated maximum.
2. Application Program (non-safe) + Application Data (non-safe non-retain data only ) + Application Program (safe) + Application Data (Safe) is less than 64Mbytes. There is a global memory pool of 64 Mbytes on BMEH586040S CPU for Application Program and Application Data.
3. This data is included in both the safe and non-safe data areas.
4. 2 GB without an external memory card.
For an expanded description of the performance characteristics of M580 safety Hot Standby CPUs, refer to the Modicon M580 Safety System Planning Guide.
CPU Hot Standby Link SFP Transceivers
NOTICE
UNINTENDED EQUIPMENT OPERATION
When installing modules with fiber optic transceivers, do the following to help prevent dust and pollution from disrupting light production into the fiber optic cable.
  • Keep caps on jumpers and transceivers when not in use.
  • Insert the optical cable into the transceivers carefully, respecting the longitudinal axis of the transceiver.
  • Do not use force when inserting the cable into the optical transceivers.
Failure to follow these instructions can result in equipment damage.
Each M580 Hot Standby CPU is fitted with an SFP socket that supports a copper or fiber-optic SFP transceiver. The available SFP transceiver modules include:
SFP Transceiver

490NAC0100
RJ45 copper

490NAC0201
single-mode fiber-optic
15 km
This transceiver operates in these wavelengths:
  • receive: 1270...1600 nm
  • transmit:1270...1360 nm
Hot Standby Link Copper Cables
If you use a 490NAC0100 copper transceiver, you can elect to use either of the following 5 m Ethernet shielded twisted pair Cat5e straight copper cables to make the Hot Standby connection:
Secure Digital (SD) Memory Cards
Schneider Electric offers the BMXRMS004GPF SD memory card for Hot Standby CPUs. The card is rated for industrial use.
Racks
Each local rack in an M580 Hot Standby system, both the primary and the standby, consists of a single rack. Extensions to the local rack are not permitted. These racks are supported:
NOTE: Your choice of rack determines the available power supply, which can be either a single or a redundant power supply.
Power Supplies
As noted above, the choice of power supply depends on the previous choice of rack. Use these power supplies in M580 Hot Standby systems:
Power Supply
Power Supply Module Name
Redundant power supplies1
BMXCPS3522(H)
BMXCPS3522S
BMXCPS4002
BMXCPS4002S

Single power supplies2
BMXCPS2000
BMXCPS2010
BMXCPS3020
BMXCPS3500
BMXCPS3500
BMXCPS3540
BMXCPS4002
1. Require a BMEXBP••02 or BMEXBP••01H rack.
2. Require a BMEXBP••00 or BMXXBP••00 rack.
Exception: You can install BMXCPS4002 modules only on the following dual-bus racks (Ethernet and X Bus):
Other Local Rack Modules
The main local rack in an M580 Hot Standby system can support communication modules and embedded switching modules.
NOTE: I/O modules are not supported on the local main rack, but can be added to (e)X80 EIO drops and as distributed equipment.
You can add these modules to an M580 Hot Standby local rack:
Module Name
Description
Maximum per local rack
BMENOC0301
Ethernet communication module for distributed equipment
up to four communication modules (depends on CPU)
BMENOC0311
FactoryCast Ethernet communication module for distributed equipment
BMENOC03212
Ethernet communication module that provides Ltransparency between a control network and a device network
BMENOS0300
network option switch module
limited only by the number of available slots
BMXNRP02001
copper multi-mode fiber converter module
BMXNRP02011
copper single mode fiber converter module
PMXNOW03001
combination wireless / 3-port wired switch module
1. A BMXNRP020• can be used to extend the EIO link, but cannot be used to extend the Hot Standby link.
2. You can enable the IP forwarding service on only one BMENOC0321 module per local rack.
