CJ1-H and CJ1M CPU Unit Features Section 1-3
â– Use Variable Duty Ratio Pulse Outputs for Lighting, Power Control, Etc.
The PULSE WITH VARIABLE DUTY RATIO instruction (PWM(891)) can be
used to output variable duty ratio pulses from the CPU Unit's built-in outputs
for applications such as lighting and power control.
Origin Search
â– Use a Single Instruction for Origin Search and Origin Return Operations
A precise origin search can be executed with one instruction that uses various
I/O signals, such as the Origin Proximity Input Signal, Origin Input Signal,
Positioning Completed Signal, and Error Counter Reset Output.
Also, an origin return operation can be performed to move directly to the
established origin.
Quick-response Inputs
â– Receive Input Signals Shorter than the Cycle Time
With quick-response inputs, inputs to the CPU Unit's built-in inputs (4 inputs
max.) with an input signal width as short as 30
µs can be received reliably
regardless of the cycle time.
Serial PLC Link Function
Data links (9 max.) can be set up between PLCs using the CPU Unit’s RS-
232C port. NT Link (1:N connection) can also be incorporated in a Serial PLC
Link network, allowing the existing NT Link (1:N mode) and the Serial PLC
Link to be used together.
Note 1: PTs are included in the number of links.
Note 2: The Serial PLC Link cannot be used for PT data links.
Scheduled Interrupt Function Used as High-precision Timer
Scheduled interrupts in units of 0.1 ms have been added for CJ1M CPU Units.
An internal PV reset start function for scheduled interrupts has also been
added, so it is possible to standardize the time to the first interrupt without
using the CLI instruction. It is also possible to read the elapsed time from
either a scheduled interrupt start or from the previous interrupt. This allows
the interval timer (STIM instruction) in the CQM1H Series to be easily used for
the CJ Series.
Features of CJ1-H.CJ1M CPU Units Ver. 3.0
Encapsulate Programming into Function Blocks Using Ladder Programming or Structured Text
When using CX-Programmer Ver. 5.0 or higher, function blocks can be used
to encapsulate standard processing that is often reused and for which only I/O
data is output externally as the user interface. Function blocks can be written
using ladder programming or structured text. Structured text is particularly
effective for easily including arithmetic processing that is difficult to write in
ladder programming.
Incorporate CompoWay/F-compatible OMRON Components into FINS Network Via Serial Gateway
Using the Serial Gateway mode for the CPU Unit’s serial port enables flexible
access to CompoWay/F-compatible OMRON components from devices on
the network (e.g., PTs, PLC CPU Units, personal computers).
Store Comment/Section Data in CPU Unit’s Flash Memory
The CX-Programmer can be used to save I/O comments and other comment/
section data in the comment memory contained in the CPU Unit’s flash mem-
ory.
