This enables backup/restoration of all data in the CPU Unit including I/O com

ments if an error occurs or when adding a CPU Unit with the same specifica

tions without requiring a Programming Device.

1-5-5 Free-running Timers

The system timers used after the power is turned ON are contained in the fol

lowing Auxiliary Area words.

Name

10-ms Incrementing

Free Running Timer

Address

A000

Function

This word contains the system timer

used after the power is turned ON.

Access

Read-only

A value of 0000 hex is set when the

power is turned ON and this value is

automatically incremented by 1

every 10 ms. The value returns to

0000 hex after reaching FFFF hex

(655.350 ms), and then continues to

be automatically incremented by 1

every 10 ms.

(Unit version 3.0 or later)

100-ms Incrementing

Free Running Timer

A001

This word contains the system timer

used after the power is turned ON.

A value of 0000 hex is set when the

power is turned ON and this value is

automatically incremented by 1

every 100 ms. The value returns to

0000 hex after reaching FFFF hex

(6.553.500 ms), and then continues

to be automatically incremented by 1

every 100 ms.

(Unit version 3.0 or later)

1-s Incrementing Free

Running Timer

A002

This word contains the system timer

used after the power is turned ON.

A value of 0000 hex is set when the

power is turned ON and this value is

automatically incremented by 1

every second. The value returns to

0000 hex after reaching FFFF hex

(65.535 s), and then continues to be

automatically incremented by 1

every second.

TXDU(256): TRANSMIT VIA SERIAL COMMUNICATIONS UNIT

RXDU(255): RECEIVE VIA SERIAL COMMUNICATIONS UNIT

Supporting no-protocol communications with Serial Communications

Boards with unit version 1.2 or later:

TXD(236): TRANSMIT

RXD(235): RECEIVE

• Model Conversion Instructions:

When using CX-Programmer Ver. 5.0 or higher to convert a C-series lad

der program for use in a CS/CJ-series CPU Unit, the C-series

XFER(070), DIST(080), COLL(081), MOVB(082), and BCNT(067)

instructions will be automatically converted to the following instructions.

The operands do not require editing.

XFERC(565) BLOCK TRANSFER

DISTC(566) SINGLE WORD DISTRIBUTE

COLLC(567) DATA COLLECT

MOVBC(568) MOVE BIT

BCNTC(621) BIT COUNTER

• High-speed Counter/Pulse Output Instructions (CJ1M Only):

High-frequency calculation methods have been added to the pulse fre

quency calculation methods for PRV(881) (HIGH-SPEED COUNTER PV

READ) and PRV2(883) (PULSE FREQUENCY CONVERT) instructions.

PRV(881) can also be used to read the pulse output frequency
