How to Encode a number using Telephony Binary-Coded Decimal encoding?įirst, Group all the numbers into pairs, and reverse each pair.īecause 1 & 2 are swapped to become 21, 3 & 4 are swapped to become 34, 5 & 6 become 65, that’s how we get that result. I got you.Īgain I found myself staring at encoding trying to guess how it worked, reading references that looped into other references, in this case I was encoding MSISDN AVPs in Diameter. Use the Data Type radio buttons to display Basic, 1D Array or 2D Array data types.Chances are if you’re reading this, you’re trying to work out what Telephony Binary-Coded Decimal encoding is. The Add Tags window gives you a list of all available data types when you are creating your tag names. To assign a Data Type to a new tag name, open the Tag Database and select “ Add Tags” button. If you are looking for pre-existing tag names with specific data types, use the check boxes at the top of the Tag Database dialog to filter your view. Assigning a Data Typeīy default, Tag Names of all data types are visible in the Tag Database.

If the value is outside this range, the precision is not as good as the Integer, 32 Bit data type. * Float 32 has 24 bit precision meaning that if the number is between -16,777,216 to +16,777,216 the resolution is less than 1, which is better than integer. When entering a constant, the field is defined by the data entered and assumes those ranges. Constants can be integers (signed 32 bit), floating point or strings.

Constant: A fixed value that is a valid replacement for a numeric or Boolean tag name in many instruction parameters (see the individual instruction help topics for more details).

String data types are used for all string manipulation, ASCII, email & LCD instruction where text is used.

String: ASCII or text representation which allocates one byte (8 bits) per character.

Float data types are used for any numerical tag where greater precision * is required, values above 32 bit integer are needed, or where variables being read into the controller are in the IEEE format.

Float, 32 Bit: IEEE formatted floating point number ranging from -3.39x1038 to +3.39x1038.

Integer, 32 bit BCD data type is used for numerical tags where variables can only represent in the range from 0-9 within the half-byte boundary.

Integer, 32 Bit BCD: Unsigned Binary Coded Decimal value ranging from 0 to +99999999.

Integer, 32 Bit data type is the default for most numerical tags where variables have the potential for negative or positive values. Integer, 16 bit BCD data type is used for numerical tags where variables can only represent in the range from 0-9 within the half-byte boundary.

Integer, 16 Bit BCD: Unsigned Binary Coded Decimal value ranging from 0 to +9999.

Integer, 16 bit Unsigned data type is used for numerical tags where only positive variables will be used.

Integer, 16 Bit Unsigned: Unsigned whole or natural numbers ranging from 0 to +65535.

Integer, 16 bit data type is used for numerical tags where variables have the potential for negative or positive values.

Integer, 16 Bit: Signed Integers ranging from -32768 to +32767.

Integer, 8 bit Unsigned data type is used for numerical tags where only positive variables will be used within a byte boundary.

Integer, 8 Bit Unsigned: Unsigned whole or natural numbers ranging from 0 to +255.

Boolean data types are used for all discrete I/O point tag names as well as internal tag names used for logic control. The controller represents True as a logical “ 1” and False as a logical “ 0”. Boolean: Also referred to as logical data types, having one of two values, True or False.* With the exception of a constant data type, each of the above data types are also available as Array data types, one dimensional (1D) Arrays & two dimensional (2D) Arrays. There are multiple Data Types available for configuring parameters and tags within a project.
