22.2 Logical Negation 1011 22 22.2 Logical Negation NOT(_E) These functions output the logical negation of input values. Setting data ■Descriptions, types, and data types Processing details ■Operation processing • These functions calculate the logical negation for each bit of the BOOL, WORD, or DWORD type data input in (s), and output the operation result from (d) in the same data type as (s). Ex. When the data type is WORD • A value input to (s) is the BOOL, WORD, or DWORD type data value. ■Operation result 1. Function without EN/ENO The ope ...

8.8 Character String Operation Instruction 437 8 Precautions • For direct specification, up to 32 characters can be specified (input). When word devices are specified in (s1) or (s2), this restriction (up to 32 characters) is not applicable. • When the values in both (s1) and (s2) start from "00H" (that is, when the number of characters is "0"), "0000H" is stored in (d). Operation error Error code (SD0/SD8067) Description 2820H In the corresponding device range after the device specified by (s1), "00H" does not exist. In the corresponding device range after th ...

26.3 Multiplication 1045 26 ■Operation result 1. Function without EN/ENO The operation processing is executed. The operation output value is output from (d). 2. Function with EN/ENO The following table lists the execution conditions and operation results. *1 When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is not used. Operation error There is no operation error. Execution condition Operation result EN ENO (d) TRUE (Executes operation) TRUE Operation output value FALSE (Stops operation) ...

8.9 Real Number Instruction Single-precision real number comparison DECMP(P) These instructions compare two data values (single-precision real number), and output the result (larger, same or smaller) to three consecutive bit devices. Setting data ■Descriptions, ranges, and data types ■Applicable devices Processing details • These instructions compare the comparison value (s1) with the comparison source (s2) as floating point data, and one of the bits among (d), (d)+1, and (d)+2 turns on according to the result (smaller, same or larger). • When the cons ...
