Positioning HART Analog eX80 I/O Modules in a Network
You can use the HART analog eX80 I/O module as:
-
local I/O in the main local BMEXBP••00 Ethernet backplane in an M580 system.
-
remote I/O modules in the main Ethernet BMEXBP••00 rack of a remote I/O drop, in either an M580 or a Quantum system.
NOTE: You can mount a HART analog eX80 I/O module only in the main segment of a local rack or a remote I/O drop. You cannot mount a HART analog eX80 I/O module in a rack extension.
The HART analog eX80 I/O modules support the following asset management software programs:
You can add up to 6 HART analog I/O modules to a main local rack. In addition to the I/O modules, the local rack includes the following components:
-
a BMEXBP••00 rack
-
a BMEP58•0•0 CPU
An example of a single local rack installation:
1
Local rack containing a BMEP583040 CPU, power supply, and 6 I/O modules
2
Maintenance PC, operating as HART primary master, connected to the local rack via Ethernet copper cable
3
HART field instruments connected to I/O via 4-20 mA current loop wiring
You can add up to 7 HART analog I/O modules to the main rack of a remote I/O drop. In addition to the I/O modules, the remote I/O rack includes the following components:
-
a BMEXBP••00 rack
-
a BMECRA31210 adapter
An example of a single local rack with a remote I/O drop:
1
Local rack containing a BMEP583040 CPU, power supply, and 6 I/O modules
2
Remote drop containing a BMECRA31210 adapter and 7 I/O modules
3
HART field instruments connected to I/O via 4-20 mA current loop wiring
4
Maintenance PC, operating as HART primary master, connected to the local rack via Ethernet copper cable
5
Remote I/O main ring
