ABB XVC768AE103/3BHB007211R0103 Circuit control board

Description

XVC768AE103 Analog modules convert between electrical signals (current or voltage) and digital values. These

digital values are 0 to 4095 (for 12-bit converters). Digital values are often referred to as “counts”.

They represent the data that is transferred between the Bus Interface Unit and an analog module.

To make the input or output data of conventional analog modules more meaningful to the

application, XVC768AE103 the Bus Interface Unit performs a conversion process called scaling (note that the BIU

performs scaling only for conventional analog modules; “intelligent” analog modules perform their

own scaling). Scaling converts the module’s digital values to or from the engineering units values

used by the application.

XVC768AE103 Typically, the engineering units represent millivolts or microamps. In other cases, they represent

physical units such as degrees or centimeters per second. Since engineering units values are

integers from -32767 to +32767, it is often necessary to use fractional units (such as hundredths of

degrees) to preserve the resolution of a physical input or output.

Each channel of an analog module can be scaled independently. XVC768AE103 Scaling is configured by entering

corresponding low and high engineering units values and low and high internal values for two

points. The internal values represent millivolts or microamps.

The BIU uses the straight line defined by the two pairs of values to convert between engineering

units and analog convertor counts. The conversion takes into account the module type and the

range that is selected.

If the circuit will not use millivolt or microAmp units, the most accurate scaling values can be

found by taking actual measurements of the process. The process must be set to two distinctly

different conditions, so two sets of measurements can be taken.

If the analog module is already installed, you can use it online to the process being measured to

obtain actual data values. By default, the Bus Interface Unit performs a 1 to 1 scaling on all

channels. (Using the online method requires the prior configuration of at least the serial bus

address, the I/O map, and the module I/O references).

XVC768AE103 Finding the Digital Value with the Module Online to the Process

If the module is online to the process, follow the steps below to find the scaling values.

1. Set the process to the first condition to be measured.
2. Using a suitable external device, find the engineering units measurement (for example, PSI, or

degrees).

3. Read the corresponding value with the Hand-held Monitor or the programmer software. The

units (using the default scaling) are millivolts or microAmps.

using a Hand-held Monitor in default mode, go to the Monitor screens and read the

channel’s digital value.

using the programmer software, go to the appropriate data table and read the channel’s

digital value.

4. Set the process to the second condition to be measured and repeat steps 2 and 3 to find the

second pair of scaling values.

Finding the Digital Value without the Module Online

XVC768AE103 If the module is not online to the process, you will need to take two measurements from the

process, and also measure the voltage or current associated with each. Convert this measurement to

millivolts (for voltage) or microAmps (for current)
