When using a 5601 with F
transmitter is done via DeltaV or other Fieldbus Host. With the help of Device
descriptors these hosts are able to present, read, and write necessary
information and data within the transmitter and assist the user to a successful
configuration of the transmitter.
In some cases, there could be a need for a more advanced service access to
the transmitter. This is done by using the Radar Master and accessing the
data from the Sensor Bus Port, which is always readily available. Below are
instructions of how to connect this port and how to use it.
The electrical interface is RS-485 (2-wire) and the language spoken (protocol)
is Modbus.
To be able to connect to the Sensor Bus on the Rosemount 5601, you must
have a RS-232/485 converter. Below you find two models of such
RS-232/485 modems which have been successfully used to communicate
with the 5601 on the Sensor Bus. Basically any type of RS-232/485 converter
can be used but different Models use different switches/settings etc., and
therefore they are not listed here. The recommended type for field use is the
K2.
The converter is to be connected on the Sensor Bus Port which is normally
used by the Rosemount 2210 Display Unit. Disconnect the communication
wires (X2: 6 & 7) to the Display Unit.
