BM100 Remote Operation - HC 275 / AMS Dev.-Rev. EE, DD-Rev. 03

1 General Information

The BM100 is a two-wire transmitter with 4..20mA current output and HART® capability.

General characteristics of the BM100 HART® interface:

Multidrop Mode is supported.

•

Burst Mode is not supported.

•

Electrical connection (point-to-point or multidrop): refer to section

„Installation and Maintenance Manual. Reflex-Radar BM100“ BM100”

1.1 Configuring Instruments for Multidrop

There are differences in configuring instruments for multidrop mode from remote or via device local keypad.

If the instrument is entering multidrop via HART® interface (any application can be used), i.e.

•

its bus address is changed from ‘0’ to any allowed, then all the necessary operations with the instrument current output are done automatically (by the HART® transmitter). If the instrument local keypad is used, the user must manually carry out the three assignments:

•

1. Set the desirable bus address (Fct. 1.6.2),

2. Set the first current output (primary current) range to “4 – 20 mA” (Fct. 1.3.2),

3. Switch the first current output function to “Off” (Fct. 1.3.1) and store configuration.

1.2 Device Unique HART® Address

It is worth noting that the Device Identification Number (defining the three low significant bytes of the long frame device address) is derived from the ‘French Command Number’ parameter (Fct.

1.4.6, Ser. 3.4), but not from the device ‘Serial Number’ (Fct.1.4.5, Ser.3.3)!

2 HART® Transmitter Revisions and Instrument Firmware

2.1 Device Revisions

The BM100 HART® transmitter at a moment has only one revision: noting that the contents of this document corresponds to the instrument

Device revision 1.

Firmware version 2.01+

for all the previous firmware versions the HART® interface support had just an intermediate (development) state and could be delivered solely due to customer insistence.

2.2 DD Revisions
