BOOL Address of a binary bit - a logical Boolean on or off state. This type is typically used for contacts or coils.

CHANNEL This is a special data type, for backward compatibility. It is an address (non-bit) to data of any type (unsigned or signed, one or more words), so can be used in place of any of the above data-types except NUMBER and BOOL. The data type is weak, and so checking is limited (e.g. CX-Programmer cannot check if the address is being used for BCD or binary values).

NUMBER A literal numeric value. Not an address. The value can be signed, or floating point. WWW.PLCJS.COM——可编程控制器技术门户

NUMBERs are used for any literal value or for timer/counter identifiers (in this case, only unsigned integer values are allowed). Floating point values are only suitable within IEEE REAL type operands.

Note: when used as BCD number operands, the value is treated as a hexadecimal value (e.g. using a NUMBER E234Eis equivalent to typing E1234Eas the operand, so that the decimal interpretation is made of the value). The value of a NUMBER data type is assumed to be decimal, unless it is prefixed with # for a hexadecimal value.WWW_P※LCJS_CO※M－PLC－技－.术_网
