EXP
Exponent
When input is on, e is raised to the power S1·S1+1
designated by source device S1 and is stored to the
destination designated by device D1.
e (base of natural logarithm) = 2.7182818

D1·D1+1
YES
POW
Power
When input is on, binary data designated by source
device S1 is raised to the power S2·S2+1 designated by
source device S2 and the operation result is stored to the
destination designated by device D1.

D1·D1+1
YES
FIFOF
FIFO Format When input is on, FIFOF instruction initializes an FIFO
data file. Each data file has unique number 0 through 9.
A maximum of 10 data files can be used in a user
program.
NO
FIEX
First-In Execute
When input is on, the data stored in data registers
starting with the device designated by S1 is stored to the
corresponding FIFO data file.
YES
FOEX
First-Out Execute
When input is on, the data is retrieved from the
corresponding FIFO data file and stored to the data
registers starting with the device designated by D1.
YES
NDSRC
N Data Search
When input is on, a value specified by device S1 is
sought. Data registers are searched, starting with the
data register designated by device S2. Device S3
specifies the quantity of 1-word or 2-word blocks of data
registers to search, depending on the data type.
The offset of the data register where a match first occurred
is stored in data register designated by device D1. The
quantity of times the value was matched is stored in the
next data register. When the search results in no match,
65535 is stored in device D1 and 0 is stored in device D+1.
NO
TADD
Time Addition
When input is on, time data designated by source device
S2 are added to date/time data designated by source
device S1, depending on the selected mode. The result is
stored to destination device D1 and carry (M8003).
S1 + S2
→
D1, CY
YES
TSUB
Time Subtraction
When input is on, time data designated by source device S2
are subtracted from date/time data designated by source
device S1, depending on the selected mode. The result is
stored to destination device D1 and borrow (M8003).
S1 – S2
→
D1, CY
YES
HOUR
Hour
While input is on, the ON duration is measured. The
measured time value (hour, minute, and second) is stored
to 3 consecutive data registers designated by destination
device D1 and compared with the preset value designated
by source device S1. When the D1 value reaches the S1
value, an output or internal relay designated by destination
device D2 is turned on. Two data registers starting with
destination device D3 are reserved for system work area.

HTOS
HMS to Sec When input is on, time data in hours, minutes, and
seconds designated by source device S1 is converted into
seconds. The result is stored to destination device D1.

YES
STOH
Sec to HMS When input is on, time data in seconds designated by
source device S1 is converted into hours, minutes, and
seconds. The result is stored to destination device D1.
