Processing details
■Operation processing
• Converts time type data input to (s) into string type data, and outputs the operation result from (d).

T#20m34s567ms
Time type
s
T#-20m34s567ms
Time type
• When SM701 (signal for switching the number of output characters) is OFF, "00H" is stored to the end of the character
string.
• The operation results stored to (d) are as follows.
For the first character, 20H (space) is stored if the BIN data is positive, and 2DH (-) is stored if it is negative.
20H (space) is stored to the left of significant figures.
■Operation result
• Function without EN/ENO
An operation is executed and the operation value is output from (d).
• Function with EN/ENO
The following table shows the executing conditions and operation results.
EN
TRUE (Operation execution)
FALSE (Operation stop)
*1 When FALSE is output from ENO, the data output from (d) is undefined. In this case, create a program so that the data output from (d) is
not used.
