15.43 Converting TIME to STRING
TIME_TO_STRING(_E)
These functions convert TIME type data to STRING type data.
â– Descriptions, types, and data types
â– Operation processing
• These functions convert the TIME type data input to (s) to STRING type data and output from (d).
• A value input to (s) is the TIME type data value.
• 00H is stored at the end of the character string when SM701 (output character number selector signal) is off.
• The following shows the operation result to be stored in the output.
â– 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.
There is no operation error.

Argument Description Type Data type
EN Execution condition (TRUE: Execution, FALSE: Stop) Input variable BOOL
s Input Input variable TIME
ENO Output status (TRUE: Normal, FALSE: Abnormal) Output variable BOOL
d Output Output variable STRING(11)
• As the 1st character, "20H" (space) is stored if the binary data is positive, and "2DH" (-) is stored if the data is negative.
• "20H" (space) is stored on the left side of the effective digits.
