CJ1-H and CJ1M CPU Unit Features Section 1-3
FINS commands can only be sent across up to 8 network levels when the
destination is a CPU Unit. FINS commands can be sent to other destinations
up to 3 network levels away.
Online Connections to
PLCs via NS-series PTs
Downloading, uploading, and monitoring of ladder programs or other data is
possible to a PLC connected serially to an NS-series PT from the CX-Pro-
grammer connected to the NS-series PT by Ethernet.
Easier Implementation of
Explicit Messages with
Explicit Message
Instructions
Special Explicit Message Instructions are now supported to simplify using
explicit messages. (Previously, CMND(490) had to be used to send a FINS
command of 2801 hex to enable sending explicit messages.) The new instruc-
tions include the following: 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)). Of these, EXPLICIT WORD READ
(ECHRD(723)) and EXPLICIT WORD WRITE (ECHWR(724)) enable easily
reading and writing data in CPU Units on networks with the same type of
notation as used for SEND(290) and RECV(298). (Does not apply to C200HX/
HG/HE and CV-series PLCs.)
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).
Use No-protocol Communications at Multiple Ports
No-protocol communications can be performed via the serial ports of Serial
Communications Boards/Units with unit version 1.2 or later. This enables no-
protocol communications at multiple ports.
Greater Flexibility in I/O Allocations
First Word Address
Settings for Slots (Using
CX-Programmer Version
3.1 or Higher)
When editing I/O tables for CJ1-H/CJ1M CPU Units, the first word address
can be set for up to 64 slots. This can be used, for example, to create fixed
starting addresses for Input Units and Output Unit to separate I/O allocations
from the program and increase the efficiency of program maintenance.
Automatic Transfer at Power ON
Automatic Transfers at
Power ON without a
Parameter File (.STD)
The user program can be automatically transferred to the CPU Unit at power
ON without a parameter file (.STD) if the name of the program file (.OBJ) is
changed to REPLACE on the CX-Programmer and the file is stored on a
Memory Card. This can be used, for example, to enable transferring a pro-
gram to a CPU Unit by creating the program offline and sending it as an email
attachment, without a local Programming Device.
Automatic Detection of I/O
Allocation Method for
Automatic Transfer at
Power ON
(CJ1-H and CJ1M CPU
Units Ver. 2.0 or Later)
The method used to create the parameter file (AUTOEXEC.STD) for auto-
matic transfer at power ON (automatic I/O allocation at startup or user-set I/O
allocation) is recorded. When an automatic transfer at power ON is executed
from the Memory Card, the recorded method is automatically detected and
used to create the I/O tables.
For example, this method can be used to create files for automatic transfer at
power ON in an office where Units are not mounted yet. The files can be
stored in a Memory Card, which can then be taken and installed in a CJ-
series CPU Unit at the remote site. When automatic transfer at power ON is
