Data Types In addition to an address or number a symbol has a data type This describes the physical format of the data that is held within the symbol including its size Since a symbol s format is known CX Programmer is able to monitor the contents of the symbol in the correct way More importantly CX Programmer checks that the symbol is not used in an inappropriate manner For example a symbol can be defined with a data type of UINT_BCD which means that the data within the address is unsigned single word integer of BCD format CX Programmer checks that the symbol is used only for BCD type instructions and issues a warning if it is not The available data types are listed below An icon is associated with each type which indicates the internal format of the type The icon is shown in the symbol tables Name Size Binary Address of a ae binary value Bit Used for contacts and coils CHANNEL 1 or Address of a non bit value i e a single more word or longer value unsigned or signed words This type is used for backward compatibility If a non bit address is given a comment the resulting symbol is given a CHANNEL type Revision3 0 Page 81 CHAPTER 4 Reference OMRON DINT Address of a double integer LINT Address of a long integer NUMBER Yes Decimal A literal value not an address NUMBER type symbols can be used for numeric operands which are usually prefixed with amp
