Upgrades for CJ1M CPU Unit Ver. 2.0

Pulse Outputs
S-curve Accelerations/
Decelerations
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.
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.
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.
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.
This section describes the upgrades accompanying Ver. 2.0 of the CJ1M CPU
Units.
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.
