CJ1-H and CJ1M CPU Unit Features Section 1-3

EXPANDED BLOCK COMPARE (BCMP2(502)) for Comparison Judgements for Up to 256 Ranges

(Upper/Lower Limits) with One Instruction

This instruction determines if a value is within any of up to 256 ranges defined

by upper and lower limits. When used with the GRAY CODE CONVERSION

(GRY(474)) instruction, the same operation as a cam switch can be achieved

by determining if an angle input from an Absolute Encoder is in a comparison

table.

Easier Processing of I/O Devices with Special I/O Instructions

Previously many instructions were required to read or write data for external

input devices such as digital switches and 7-segment displays connected to

Basic I/O Units. Now, I/O processing for these devices can be achieved with a

single instruction. These are sometimes call Combination Instructions.

These instructions are the same as those supported by the C200HX/HG/HE

and CQM1H PLCs, with the exception that more than one of each of these

instructions can be executed in a single user program.

TEN KEY INPUT (TKY(211))

Sequentially reads numbers input from a ten-key connected to an Input Unit.

HEXADECIMAL KEY INPUT (HKY(212))

Sequentially reads numbers input from a hexadecimal keypad connected to

an Input Unit and an Output Unit for a maximum of 8 digits.

DIGITAL SWITCH INPUT (DSW(213))

Reads numbers input from a digital switch or thumbwheel switch connected to

an Input Unit and an Output Unit. Either 4 or 8 digits are read.

MATRIX INPUT (MTR(210))

Sequentially reads 64 input points input from a 8 x 8 matrix connected to an

Input Unit and an Output Unit.

7-SEGMENT DISPLAY OUTPUT (7SEG(214))

Converts 4-digit or 8-digit values to data for a 7-segment display and outputs

the result.

Read/Write CPU Bus Unit Memory Areas with IORD(222)/IOWR(223)

Although INTELLIGENT I/O READ (IORD(222)) and INTELLIGENT I/O

WRITE (IOWR(223)) could previously be used only for Special I/O Units,

these instructions can now be used to read and write data for CPU Bus Units.

Operation Start/End Times

The times that operation is started and ended are automatically stored in

memory in the Auxiliary Area (A515 to A517). This enables easier manage-

ment of the operating times of the PLC System.

1-3-8 Upgrades for CJ1M CPU Unit Ver. 2.0

This section describes the upgrades accompanying Ver. 2.0 of the CJ1M CPU

Units.

Pulse Outputs

S-curve Accelerations/

Decelerations

S-curves can be specified for the acceleration/deceleration rates for Pulse

Output Instructions with accelerations/decelerations (ACC(888), PLS2(883),

and ORG(889)). When there is leeway in the maximum allowable speed, S-

curve accelerations/decelerations will help control shock and vibration by

reducing the initial acceleration rate in comparison with linear acceleration/

deceleration.
