High-speed
Counter and
Pulse Output
Instructions
MODE CONTROL INI/
@INI
880 INI(880) is used to start and stop target value comparison, to change the
present value (PV) of a high-speed counter, to change the PV of an interrupt
input (counter mode), to change the PV of a pulse output, or to stop pulse out-
put.
2-308
HIGH-SPEED
COUNTER PV
READ
PRV/
@PRV
881 PRV(881) is used to read the present value (PV) of a highspeed counter, pulse
output, or interrupt input (counter mode).
2-311
COMPARISON
TABLE LOAD
CTBL/
@CTBL
882 CTBL(882) is used to perform target value or range comparisons for the
present value (PV) of a high-speed counter.
2-315
SPEED OUTPUT SPED/
@SPED
885 SPED(885) is used to specify the frequency and perform pulse output without
acceleration or deceleration.
2-319
SET PULSES PULS/
@PULS
886 PULS(886) is used to set the number of pulses for pulse output. 2-323
PULSE OUTPUT PLS2/
@PLS2
887 PLS2(887) is used to set the pulse frequency and acceleration/deceleration
rates, and to perform pulse output with acceleration/deceleration (with different
acceleration/deceleration rates). Only positioning is possible.
2-325
ACCELERATION
CONTROL
ACC/
@ACC
888 ACC(888) is used to set the pulse frequency and acceleration/deceleration
rates, and to perform pulse output with acceleration/deceleration (with the
same acceleration/deceleration rate). Both positioning and speed control are
possible.
2-331
ORIGIN SEARCH ORG/
@ORG
889 ORG(889) is used to perform origin searches and returns. 2-336
PULSE WITH
VARIABLE DUTY
FACTOR
PWM/
@PWM
891 PWM(891) is used to output pulses with a variable duty factor. 2-339
Step
Instructions
STEP START SNXT 009 SNXT(009) is used in the following three ways:
(1)To start step programming execution.
(2)To proceed to the next step control bit.
(3)To end step programming execution.
2-342
STEP DEFINE STEP 008 STEP(008) functions in following 2 ways, depending on its position and whether
or not a control bit has been specified.
(1)Starts a specific step.
(2)Ends the step programming area (i.e., step execution).

Basic I/O Unit
Instructions
I/O REFRESH IORF/
@IORF
097 Refreshes the specified I/O words. 2-352
7-SEGMENT
DECODER
SDEC/
@SDEC
078 Converts the hexadecimal contents of the designated digit(s) into 8-bit, 7-seg-
ment display code and places it into the upper or lower 8-bits of the specified
destination words.
2-354
DIGITAL SWITCH
INPUT
DSW 210 Reads the value set on an external digital switch (or thumbwheel switch) con-
nected to an Input Unit or Output Unit and stores the 4-digit or 8-digit BCD data
in the specified words.
2-357
MATRIX INPUT MTR 213 Inputs up to 64 signals from an 8 ⋅ 8 matrix connected to an Input Unit and
Output Unit (using 8 input points and 8 output points) and stores that 64-bit data
in the 4 destination words.
2-361
7-SEGMENT DIS-
PLAY OUTPUT
7SEG 214 Converts the source data (either 4-digit or 8-digit BCD) to 7-segment display
data, and outputs that data to the specified output word.
2-365
Serial Com-
munications
Instructions
TRANSMIT TXD/
@TXD
236 Outputs the specified number of bytes of data from the RS-232C port built into
the CPU Unit or the serial port of a Serial Communications Board (version 1.2
or later).
2-369
RECEIVE RXD/
@RXD
235 Reads the specified number of bytes of data from the RS-232C port built into
the CPU Unit or the serial port of a Serial Communications Board (version 1.2
o
r later).
2-374
