Network Termination Jumper

On the terminal block PCBA there is a jumper, J1 (see gure UUUU), that enables or

disables a network termination resistor as dened below:

When the network jumper is placed in the ON position there is a 120 ohm termination

resistor in place. When the network jumper is placed in the OFF position there is no

termination resistor in place.

Default: OFF

BACnet Objects:

Device Object

The default object identier is 607xxx, where xxx is replaced by the MS/TP MAC

address set in the Network Address menu. The object identier value will change as

the MS/TP MAC address changes. However, if a specic object identier is written

via BACnet, then that value is stored and changes to the MS/TP MAC address will no

longer affect the object identier.

Similarly, the default object name includes 607xxx. The object name will reect the

current object identier. If a specic object name is written via BACnet, then that value

is stored and changes to the object identier will no longer affect the object name.

APDU Timeout values are rounded to the nearest second (1000ms). Values less than

500 will be rounded to 0 and Number of APDU Retries will be set to 0.

Binary Value – Reverse Flow

This object provides a simple indication of the direction of process ow. When the

process uid is detected as owing in the normal direction, the present value will return

inactive(0). When the process uid is detected as owing in the reverse direction, the

present value will return active(1).

This object supports COV subscription to allow a monitoring system to easily detect

changes in ow direction.

Binary Value – Empty Pipe

This object provides a simple indication of an error state where no process ow is

in contact with the probe. When the process uid is detected, the present value will

return inactive(0). When the process uid is not detected, the present value will return

active(1).

This object supports COV subscription to allow a monitoring system to easily detect

this error condition.

Binary Value – Reset Total Flow

Writing a value of 1 to the present value of this object will reset the value of Total Flow

to 0. Writing a value of 0 has no effect.

Modbus®Registers

Input Registers

The String data type is read as a

stream of ASCII characters with the rst

character sent in the MSB of the rst

register and the second character sent

in the LSB of the rst register and so on.

If the string is shorter than the allotted

size, the remaining bytes will be zero

padded.

Holding Registers

Device Name: A string, up to 40 characters long, that will be displayed on the LCD (if

present). When reading or writing, all 20 registers must be requested. Strings less than

40 characters shall be 0 padded.

Velocity Unit: Selects the unit of velocity for the value in the velocity register. See

Table 1.

Flow Unit: Selects the unit of ow for the value in the Flow register. See Table 2.

Volume Unit: Selects the unit of volume for the value in the Total Flow register. See

Table 3.

Reset Total Flow: When a value of 1 is written to this register, the value in the Total

Flow register is reset to 0. Writing a value of 0 has no effect. This register will always

return a 0 when read.

Reset Device: When a value of 1 is written to this register, the device will perform a

warm reset after 5 seconds. Writing a value of 0 has no effect. This register will always

return 0 when read.

* Default unit

Multi-Address Support

Multi-Address support allows a register to be read or written to using different byte

orientations specied by the address range. For example, input register 0003 can

also be read at 2003, 4003 and 6003 with different byte orientations as listed in Table

7. Registers that do not have multi-address support are only available in Big-Endian

byte orientation (Modbus® standard).
