3.4.2 Device Variable Mapping

Device Variables may be mapped to the Dynamic Variables according to the following table:

Table 3.6 – Mapping of Device Variables to Dynamic Variables

Variable

Code

Dynamic

Variable

Direction Default Device Variable

Device Variables which may be mapped to the

Dynamic Variable

0 PV input Position Setpoint Position Setpoint

1 SV output Current Position Current Position or Torque

2 TV output Motor Temperature

Current Position, Torque, Motor Temperature or

Compartment temperature

3 QV output Compartment Temperature

Current Position, Torque, Motor Temperature or

Compartment temperature

No single Device Variable may be mapped to more than one Dynamic Variable.

For Example:

Valid Mapping: Invalid Mapping:

PV = DV0 PV = DV0

SV = DV1 SV = DV1

TV = DV3 TV = DV1

QV = DV4 QV = DV4

If you try to map two Dynamic Variables to the same Device Variable, the command will return response code 2 “invalid

selection”. The Device Variables may be mapped from the DD menu Device Setup->Wired HART Board->Conﬁguration->

Device Variable Mapping as follows:

Figure 3.1 – Device Variable Mapping Setup

3.4.3 Device Variable Units

Device Variables 0, 1, and 2 have ﬁxed units that may not be changed. Device Variables 3 and 4 have units that may be

interchanged between °C and °F the default is °F. For Device Variables 3 and 4, the units may be changed from the DD menu

Process Variables->Wired HART Board as follows:

1 2 ... 16 17 18 19 20 21 22 23 24 25 26 ... 71 72
