6 Variable description

PD 340 Flow Transmitter holds a number of variables and functions, which all may be ac-
cessed via P-NET and some via the PD 210 display unit.
6.1

SoftWire Table

The variables in the PD 340 Flow Transmitter are located at logical addresses called Soft-
Wire numbers. These variables are use to define the size of the meterhead, setpoint for the
PI regulator, function of output signals etc. An overview of these variables and related Soft-
Wire numbers are shown in the following SoftWire table. The memory type is explained in
Appendix 1.
At delivery, the transmitter is programmed for the functions specified on the order.
