10.8.2 Transducer Input Scaling Configuration

The floating point values for the Transducer Input points on all present Transducer Input

Modules will appear in the M87x floating point database. By default, values for Transducer

Inputs configured as voltage inputs will be in volts and values for Transducer Inputs

configured as currents will be in milliamps.

Database points for which there are no

corresponding Transducer Input points will report as zero.

The 70 Series Configurator software provides for gain and offset scaling for each

Transducer Input. This permits transducer inputs to appear in primary units. The 70

Series Configurator allows the user to enter two specific primary values for the associated

transducer input values and automatically calculates the correct offset and gain

corrections. See Figure 23 (70 Series Configurator Software Transducer I/O Configuration

Screen).

In the screen snap shot shown in the Figure 23, the first Transducer Input card has the first

three inputs configured for type 0-1mA, inputs 4 through 6 configured for type 4-20mA

inputs, and the remaining two inputs configured as type 0-10V inputs. All inputs except for

5 and 6 will appear in the database in default units (milliamps for inputs 1 through 4 and

volts for inputs 7and 8).

The poll rate is now settable through the Transducer Input page. Poll rate has been added

as a settable value starting with the release of Configurator v3.02. A poll rate as low as

100 ms can now be set for certain applications. Refer to the specifications when setting the

poll rate for Transducer Inputs on M87x. See Figure 23, which shows an example of

settings made using the 70 Series Configurator Software on the Transducer Input page.
