Introduction
An X80 RIO drop can have one or two racks:
main RIO rack: BMEXBP••00 or BMXXBP••0
This rack is required in a drop and contains a BMXCRA31200, BMECRA31210, or BMXCRA31210 EIO adapter module, a power supply, and, optionally, I/O modules.
extended RIO rack: only BMXXBP••0
This rack is optional in a drop and contains only I/O modules.
Confirm that extended remote racks are PV 02 or later. Install modules that require Ethernet across the backplane on the main remote rack.
NOTE: The BMXCRA31200 does not support an extended RIO rack.
Compatible Racks
Use these racks in an Modicon X80 RIO drops:
X BUS (PV 02 or later) backplanes:
BMXXBP0400
BMXXBP0600
BMXXBP0800
BMXXBP1200
BMXXBP0400H
BMXXBP0600H
BMXXBP0800H
BMXXBP1200H
Ethernet backplanes:
BMEXBP0400
BMEXBP0602
BMEXBP0800
BMEXBP1002(2)
BMEXBP1200(1)
BMEXBP0400H
BMEXBP0602H
BMEXBP0800H
BMEXBP1002(2)
BMEXBP1200H(1)
(1) The 12-slot Ethernet rack has eight Ethernet-X Bus slots and four X Bus-only slots.
(2) The 10-slot Ethernet rack has eight Ethernet-X Bus slots and two X Bus-only slots.
Rack Selection Considerations
A BMECRA31210 performance EIO adapter module:
can be installed on an Ethernet rack only.
can be installed on a PV 02 or later backplane, but it cannot manage Ethernet modules.
cannot be installed in a PV 01 backplane because of its keying pin
A BMXCRA31210 or a BMXCRA31200 EIO adapter module:
can be installed on a PV 02 or later backplane.
can be installed on an Ethernet backplane, but it cannot manage Ethernet modules. However, it can manage modules that it manages on a PV 02 or later backplane.
Racks and Extensions
An Modicon X80 RIO drop can include two racks. In a 2-rack drop, the racks are linked with two bus extender modules and a cable:
Bus Extender Module |
Cable |
|---|---|
BMXXBE1000 |
BMXXBC•••K (0.8 to 12 m) |
Consideration of a Shielded Cable with an Accessible Metal Part
Follow all local and national safety codes and standards.
| DANGER | |
|---|---|
HAZARD OF ELECTRIC SHOCK If you cannot prove that the end of a shielded cable is
connected to the local ground, the cable must be considered as dangerous
and personal protective equipment (PPE) must be worn. Failure to follow these instructions will result in death or serious injury. | |
Do not apply power to an Modicon X80 rack until connections are made at both ends of the Ethernet cable. For example, connect the cable to both the BMECRA31210 performance EIO adapter module and another device (adapter module) or DRS before you turn on the power.
Refer to your system hardware reference manual for details about DRSs.
