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:

  • FieldCare Asset Management Software by Endress+Hauser

  • PACTware a free download from the PACTware Consortium

Local I/O

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

Remote I/O

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
