Endress+Hauser 45
51 Write assignments of the device
variables to the four process
variables
Access = Write
Set the assignment of the device variables to the four
process variables:
– Byte 0: device variable ID to the primary process
variable
– Byte 1: device variable ID to the secondary process
variable
– Byte 2: device variable ID to the third process variable
– Byte 3: device variable ID to the fourth process
variable
ID of the supported device variables:
See data ä 41
Factory setting:
• Primary process variable (vol. flow)
• Secondary process variable = temperature
• Third process variable = mass flow
• Fourth process variable = totalizer 1
The current variable assignment of the process variables
is displayed as a response:
– Byte 0: device variable ID to the primary process
variable
– Byte 1: device variable ID to the secondary process
variable
– Byte 2: device variable ID to the third process variable
– Byte 3: device variable ID to the fourth process
variable
53 Write device variable unit
Access = Write
This command sets the unit of the given device variables.
Only those units which suit the device variable are
transferred:
– Byte 0: device variable ID
– Byte 1: HART unit ID
ID of the supported device variables:
See data ä 41
!
Note!
If the written unit does not suit the device variable, the
device will continue with the last valid unit.
The current unit of the device variables is displayed in
the device as a response:
– Byte 0: device variable ID
– Byte 1: HART unit ID
!
Note!
Manufacturer-specific units are represented using the
HART unit ID "240".
59 Specify number of preambles in
message responses
Access = Write
This parameter specifies the number of preambles which
are inserted in the message responses:
Byte 0: number of preambles (2 to 20)
As a response, the current number of the preambles is
displayed in the response message:
Byte 0: number of preambles
108 Burst mode CMD
Access = Write
Select the process values that are cyclically transmitted
to the HART master.
Byte 0:
• 1 = primary process variable
• 2 = current and percentage of the measuring range
• 3 = current and four (previously defined) measured
variables
The value set in byte 0 is shown as the response.
109 Burst mode control
Access = Write
This parameter switches the burst mode on and off.
Byte 0:
• 0 = burst mode off
• 1 = burst mode on
The value set in byte 0 is shown as the response.
Command No.
