CJ1-H-R, CJ1-H, CJ1M, and CJ1 CPU Unit Comparison Section 1-7
• 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.)
