ISPSoft User Manual 6.1.3 Data Types The data type of a symbol determines the significance of the value of symbol. Suppose there are two symbols VAR_1 and VAR_2. The data type of VAR_1 is BOOL, and the data type of VAR_2 is WORD. When VAR_1 and VAR_2 are used in a program, VAR_1 represents a contact, and VAR_1 represents a 16-bit device which can be involved in arithmetic or data transfer. The data types supported by ISPSoft are listed below. Different PLC types supports different data types. However, global variable and program (local variable) are mainly the same, but symbol variables declared by function block (local variable) are different (see below).
