This type of Connection window describes the functionality for Input- and Holding Registers.

Length

The maximum length of words to read or write is 125.

Table columns

Address

In these cells you can enter a description for the data. If Hex is selected, the addresses are displayed in hexadecimal format.

Name

In these cells you can enter an optional description for the data.

Word

In these cells you can see the raw words of data. If Holding Register is selected, you can double-click, press  Space  or  Enter  on a word to input a new value.

After confirmation (if not disabled by Command line > /WriteAllways) one word will be written into your device and old data will be overwritten.

Type

Select one or more cells and select the Data type from the combo-box. Depending on that type the value column will reflect the settings. If a data type has a size of more then one word, it will occupy more than one rows and subsequent cells of these rows will be displayed as -

Scale

Select one or more cells and select the Scale from the combo-box or enter your own text.  Depending on that type the value column will reflect the settings. The syntax of scale is:
[ endian ] [ % | 1:number | minRaw;maxRaw;minValue;maxValue | number_of_characters ] [ {%format} ]

Parts of scale enclosed in [ ] are optional.
 

•If data type is numerical, typical scales are:

You can optional prefix the scale by the type of endian - see the table below:

▪BE:   -  Big Endian  (default if not present)

▪BE-S: -  Big Endian byte swap

▪LE:   -  Little Endian

▪LE-S: -  Little Endian byte swap

oNo scaling occurs if scale is empty or 1:1

oPercentage %

oScaling 1:number

oYou can define your own scaling by entering 4 values: minRaw;maxRaw;minValue;maxValue
Example: 0;511;4;20  or 0;65535;-100;100
If minRaw or maxRaw is omitted their replacements are the data type depending min- or max values.
Example: If data type is INT16 and the scale is ;;minValue;maxValue , then minRaw=-32768 and maxRaw=32767 are used.
 
If a rawValue is read from a device, then the following equation is taking place:
 value    := minValue + ( rawValue - minRaw ) * ( maxValue - minValue ) / ( maxRaw - minRaw     )
 
If a Value is written to a device, then the following equation is taking place:
 rawValue :=   minRaw + ( Value - minValue  ) * ( maxRaw - minRaw     ) / ( maxValue - minValue )
 

oIf data type is Float or Double you can define your own format. The syntax is {%[width.prec]<g|f|e|n>[other chars]}
width - optional width of the resulting number
prec - optional precision of the resulting number
g - general, minimal display of a value in floating point or engineering format
f - normal, floating point notation
e - engineering form with exponent   x.yyyEnnn
n - number format with thousand separator
%% - a single % character
 
Example: {%.5e V}  or LE-S: {%.2f [Volt]} or BE: {%.2f %%} or BE: 0;255;0;100 {%.2f r.H.}
 

•If data type is Char the cell defines the even count of characters 2,4,6, ... ,250 , the minimum characters are 2

•If data type is WChar the cell defines the count of characters 1,2,3, ... ,125

Value

Values that are out of range are displayed with a red bar ( upper limit ↑ ) or an orange bar ( lower limit ↓ ). Unknown values are displayed as ?

If Holding Registers is selected you can edit data by double-click, pressing  Enter  or by begin typing numbers on a Word or Value cell.

•Numerical values can be entered in different formats e.g.: 1,5 , -3e-13,  0x1234, 16#1234 or 2#1100´1111

•Strings have to be entered between single quotes 'AB'. Special characters can be escaped by \

After confirmation (if not disabled by Command line > /WriteAllways) one or more words will be written into your device and old data will be overwritten.
