Programming Instructions Appendix A
Expansion Instructions
The following table shows the instructions that can be treated as expansion instructions. The default function
codes are given for instructions that have codes assigned by default.
86 (@)ASC ASCII CONVERT Converts hexadecimal values from the source word to eight-bit
ASCII code starting at leftmost or rightmost half of starting
destination word.
301
87 to 89 For expansion instructions. 213
90 (@)SEND NETWORK SEND Transmits data to another node in the network. 406
91 (@)SBS SUBROUTINE ENTRY Calls and executes subroutine N. 377
92 SBN SUBROUTINE DEFINE Marks start of subroutine N. 379
93 RET RETURN Marks the end of a subroutine and returns control to main pro-
gram.
379
97 (@)IORF I/O REFRESH Refreshes all I/O words between the start and end words.
Cannot be used with the SRM1.
382
98 (@)RECV NETWORK RECEIVE Requests data transfer from another node in the network. 410
99 (@)MCRO MACRO Calls and executes a subroutine replacing I/O words. 383

17 (@)ASFT ASYNCHRONOUS SHIFT
REGISTER
Creates a shift register that exchanges the contents of adja-
cent words when one of the words is zero and the other is not.
268
18 TKY TEN KEY INPUT Inputs 8 digits of BCD data from a 10-key keypad. 434
19 (@)MCMP MULTI-WORD COMPARE Compares a block of 16 consecutive words to another block of
16 consecutive words.
285
47 (@)RXD RECEIVE Receives data via a communications port. 415
48 (@)TXD TRANSMIT Sends data via a communications port. 417
60 CMPL DOUBLE COMPARE Compares two eight-digit hexadecimal values. 284
61 (@)INI MODE CONTROL Starts and stops counter operation, compares and changes
counter PVs, and stops pulse output.
255
62 (@)PRV HIGH-SPEED COUNTER
PV READ
Reads counter PVs and status data of high-speed counters. 257
63 (@)CTBL COMPARISON TABLE
LOAD
Registers a comparison table and starts comparison for high-
speed counters.
243
64 (@)SPED SPEED OUTPUT Outputs pulses at the specified frequency (10 Hz to 50 KHz in
10 Hz units). The output frequency can be changed while
pulses are being output.
395
65 (@)PULS SET PULSES Outputs the specified number of pulses at the specified fre-
quency. The pulse output cannot be stopped until the specified
number of pulses have been output.
393
66 (@)SCL SCALE Performs a scaling conversion on the calculated value. 305
67 (@)BCNT BIT COUNTER Counts the total number of bits that are ON in the specified
block of words.
385
68 (@)BCMP BLOCK COMPARE Judges whether the value of a word is within 16 ranges
(defined by lower and upper limits).
283
69 (@)STIM INTERVAL TIMER Controls interval timers used to perform scheduled interrupts. 241
87 DSW DIGITAL SWITCH INPUT Inputs 4- or 8-digit BCD data from a digital switch. 427
88 7SEG 7-SEGMENT DISPLAY
OUTPUT
Converts 4- or 8-digit data to 7-segment display format and
then outputs the converted data.
424
89 (@)INT INTERRUPT CONTROL Performs interrupt control, such as masking and unmasking
the interrupt bits for I/O interrupts.
391
--- (@)ACC ACCELERATION CON-
TROL
Together with PULS(––), ACC(––) controls the acceleration
and/or deceleration of pulses output from port 1 or 2.
400
--- (@)ACOS ARC CoSINE Calculates the arc cosine of a 32-bit floating-point number. 366
