User Defined Tables A/B (Characteristic Curves Setup)

The characteristic curves of “Table A” and “Table B” (freely config

urable over 9 defined points) are independently configurable and

can be used among other predefined curves for each of the analog

inputs. Each point may be scaled to related values measured from

the analog input (0 to 250/500/2500 Ohms, 0 to 10 V, or 0 to

20 mA), so that the actual display and monitoring reflects the corre

sponding values (e.g. 200 to 600 kW).

The created characteristic curves can be used for scaling the

analog inputs

The X and Y junction may be moved within the range of values and

the space between setpoints can be nonuniform.

When configuring the X coordinates, ensure the coordinates

always increase in scale continuously.

In the following example the first set of x/y coordinates is correct

and the second set of x/y coordinates is wrong

Parameter CL Setting range

The event history will store this text message and it is also displayed on the

visualization screen.

If the programmed limit value of the analog input has been reached or

exceeded this text is displayed in the control unit screen.

Notes

This parameter may only be configured using ToolKit. 19 characters are best

for HMI readability – text strings with 20 and more characters but without a

blank in between are NOT visible as headline on AI {x} detail screen. AI

selection screen on HMI/display works fine with up to 30 characters; others

are overwritten by mandatory screen symbols.

The max. number of characters depends on the numbers of Bytes for each

character.

Please verify the length on the display for best view.

2 According to the following parameters different measuring ranges are pos

sible at the analog inputs.

[Off] The analog input is switched off.

VDO 5 bar The value of the analog input is interpreted with the VDO characteristics 0 to

5 bar.

VDO 10 bar The value of the analog input is interpreted with the VDO characteristics 0 to

10 bar.

VDO 150 °C The value of the analog input is interpreted with the VDO characteristics 50 to

150 °C.

VDO 120 °C The value of the analog input is interpreted with the VDO characteristics 40 to

120 °C.

Pt100 The value of the analog input is interpreted with a Pt100 characteristic.

Pt1000 The value of the analog input is interpreted with a Pt1000 characteristic.

AB 94099 The value of the analog input is interpreted with a AB 94099 characteristic.

Linear Each analog input may be assigned to a linear characteristic curve, which can

be only used for the respective defined input [T{x}] (x = 1 to 3). The minimum

value refers to the value configured as “Sender value at display min.” (param

eter 1039 Ä p. 189. 1089 Ä p. 189 or 1139 Ä p. 189). The maximum value

refers to the value configured as “Sender value at display max.” (param

eter 1040 Ä p. 190. 1090 Ä p. 190 or 1140 Ä p. 190).

Table A

Table B

The analog input is assigned to a characteristic curve which is defined over

9 points (stored in a table). Two independent tables (table A and table B) may

be allocated to the analog inputs.

Notes

Points of these tables must be programmed into the control unit before use.

For the characteristic curves of the inputs refer to Ä Chapter 9.1.2 “VDO

Inputs Characteristics” on page 658.

The value (y-axis) to be displayed for the minimum of the input range must be

entered here.

Notes

This parameter is only visible if the parameter “Type” (1000 Ä p. 189/

Ä p. 195/1050 Ä p. 189/1100 Ä p. 189) is configured to “Linear”.

The value (y-axis) to be displayed for the maximum of the input range must

be entered here.

Notes

This parameter is only visible if the parameter “Type” (1000 Ä p. 189/

Ä p. 195/1050 Ä p. 189/1100 Ä p. 189) is configured to “Linear”.

The value (x-axis) of the configured input range, which shall correspond with

the minimum value configured for the display, must be entered here. This

specifies the lower limit of the hardware range to be measured.

Description

(Sender value at

Example

If the input range is 0 to 20 mA and the value configured here is 4. an analog

input value of 4 mA would correspond with the minimum value configured for

the display.

Notes

This parameter is only visible if the parameter “Type” (1000 Ä p. 189/

(Sender value at

imum)

The value (y-axis) of the configured input range, which shall correspond with

the maximum value configured for the display, must be entered here. This

specifies the upper limit of the hardware range to be measured.

Example

If the input range is 0 to 20 mA and the value configured here is 20. an analog

input value of 20 mA would correspond with the maximum value configured

for the display.

Notes

This parameter is only visible if the parameter “Type” (1000 Ä p. 189/

Ä p. 195/1050 Ä p. 189/1100 Ä p. 189) is configured to “Linear”.
