DeltaV Data Type

This attribute defines how data will be stored in the DeltaV dataset. The following tables describes available options for PLC5/XXE, and SLC 5XX and ControlLogix processors.

PLC Data Type Access Available DeltaV Data Types Restrictions

O – Table

B – Table

R/W

Boolean with Status

Discrete with Status

16-bit aligned dataset Start Address. For example: 0, 16, 32, etc.

Number of values is multiple of 16, and refers to bits. Maximum 96 registers. Each dataset register is a bit.

16-bit Int with Status

16-bit Uint with Status

Maximum registers are 100. Starting address is any 16-bit word
I – Table R

Boolean with Status

Discrete with Status

16-bit aligned dataset Start Address. For example: 0, 16, 32, etc.

Number of values is multiple of 16, and refers to bits. Maximum 96 registers. Each dataset register is a bit.

16-bit Int with Status

16-bit Uint with Status

Maximum registers are 100. Starting address is any 16-bit word.

R/W

16-bit Int with Status

16-bit Uint with Status

Maximum registers are 100. Starting address is any 16-bit word.
F-Table R/W Floating Point with Status Maximum registers are 50. Starting address is any floating point register.
ST-Table R/W String with Status

Each string element is addressed as STXX:YY, where XX is the string file number and YY is the individual string element in the array, starting at 0 and up to the number of configured string elements.

Datatset starting address indicates String Element from PLC table.

Size is always 100, it indicates the number of characters in the string element. Maximum size of any string element in the PLC is 82 characters.

One string element from the PLC is mapped into one dataset in DeltaV
