CJ1 and CJ1-H CPU Unit Comparison Section 1-6
As a result, in the above diagram for example, files for automatic transfer at
power ON are created in an office where the Units are not mounted. The files
are then saved in a Memory Card, which is taken and installed in a CJ-series
CPU Unit at the remote site, where automatic transfer at power ON is exe-
cuted and I/O is allocated according to the I/O allocations in the mounted Unit
using the method recorded in the Memory Card.
1-5-11 New Application Instructions
The following instructions have been added. Refer to the Programming Man-
ual (W340) for details.
• Multiple Interlock Instructions:
MULTI-INTERLOCK DIFFERENTIATION HOLD (MILH(517)), MULTI-
INTERLOCK DIFFERENTIATION RELEASE (MILR(518)), and MULTI-
INTERLOCK CLEAR (MILC(519))
• TIME-PROPORTIONAL OUTPUT (TPO(685))
• GRAY CODE CONVERSION (GRY(474))
• COUNTER FREQUENCY CONVERT (PRV2(883)) (CJ1M CPU Unit only)
• Combination Instructions:
TEN KEY INPUT (TKY(211)), HEXADECIMAL KEY INPUT (HKY(212)),
DIGITAL SWITCH INPUT (DSW(213)), MATRIX INPUT (MTR(210)), and
7-SEGMENT DISPLAY OUTPUT (7SEG(214))
• Time Comparison Instructions: =DT, <>DT, <DT, <=DT, >DT, >=DT
• Explicit Message Instructions:
EXPLICIT MESSAGE SEND (EXPLT(720)), EXPLICIT GET ATTRIBUTE
(EGATR(721)), EXPLICIT SET ATTRIBUTE (ESATR(722)), EXPLICIT
WORD READ (ECHRD(723)), and EXPLICIT WORD WRITE
(ECHWR(724))
• EXPANDED BLOCK COMPARE (BCMP2(502)) (This instruction, previ-
ously supported by only the CJ1M PLCs, is now supported by the CS1-H
and CJ1-H.)
• INTELLIGENT I/O READ (IORD(222)) and INTELLIGENT I/O WRITE
(IOWR(223)) (These instructions could previously be used only for Spe-
cial I/O Units, but they can now be used to read and write data for CPU
Bus Units.)
