Communication Interface Specifications

You can use the USB port or RS-232C/422 connector of the Controller to perform serial communication with
external devices such as a personal computer or programmable controller.
Serial communication functions in the RUN mode. Communication cannot be performed in the ADJ or MENU
modes.

<USB>

This interface allows Full speed (12 Mbps) communications compliant with USB2.0 with a PC equipped with
the same USB interface.

Synchronization method Start-stop

Transmission code ASCII (Binary format can be selected only when outputting measurement values set at

[Setup] - [Support] - [Calculation] - [Data].)

Communication speed USB2.0-compliant

Data length -

Parity -

Stop bit -

Delimiter CR, LF, CR+LF

Transmission protocol Normal (Note, however, that XMODEM protocol is used when sending image data, system

data and other data.)

<RS-232C/422>

This interface allows data communications compliant with the EIA RS-232C/422 standards up to a maximum
speed of 115200 bps.

Synchronization method Start-stop

Transmission code ASCII (Binary format can be selected only when outputting measurement values set at

[Setup] - [Support] - [Calculation] - [Data].)

Communication speed 9600, 19200, 38400, 57600, 115200

Data length 7 bits, 8 bits

Parity None, even, odd

Stop bit 1 bit, 2 bits

Connection

Ferrite cores

Connecting a PC

<USB>

Use a USB cable (ZFX-XUSB) to connect the Controller to the
PC.

Important

• When connecting the PC, refer to the Instruction Manual for the PC.

• Attach the ferrite cores supplied to both ends of the USB cable.

Note

Installation of the USB driver is necessary only when connecting an external device to the USB interface for the first
time.
For the USB driver, please contact your OMRON representative.

<Ethernet>

Use a commercially available LAN cable to connect the Controller
to the PC.

There are two ways of making the LAN connection to the PC,
directly to the PC or via a hub.

Important

The following communications are not possible:

• Communications with the Controller from outside the LAN

• Communications between the Controller and two or more PCs

• Communications between Controllers

• Communications between the Controller and the PLC

• 1:1 Connection

If communications software for a TELNET
connection is activated on the PC to access the
Controller, the Controller will automatically switch to
the Ethernet connection.

The parallel interface's ENABLE signal will be OFF during measurement.

To end the Ethernet connection, input the
EXIT command.

MEASURE

IP address

192.168.250.010

Start the TELNET communications software on the PC, and
specify individual IP addresses to access each Controller.
The method for inputting commands is the same as for a 1:1
connection.

192.168.250.100

IP address

192.168.250.101

When connecting the Controller directory to the PC, use a 10BASE-T or 100BASE-TX cross cable (Category 5
or higher). Limit the cable length to 30 m.

Example: A measurement command is input and the result is acquired.

• 1:N Connection

When connecting two or more Controllers to one PC via a hub, use a 10BASE-T or 100BASE-TX straight cable
(Category 5 or higher). Also, limit the cable lengths between the PC and the hub, and the Controllers and the
hub to 30 m, respectively. Be sure to set unique IP addresses to each Controller. Do not set duplicate IP
addresses to Controllers.

Connection

ZFX-C Serial Communication Command Reference

Connecting a PLC

Use the exclusive RS-232C cable (ZFX-XPT2A) / RS-422 cable
(ZFX-XPT2B) to connect the Controller to a PLC.

Important

When connecting to a PLC, refer to the Instruction Manual for the
PLC.

Example: Number of digits of integer section: 7, number of digits past the decimal point: 3,

decimal separator: period

The following explains the output format of measurement values.
To output measurement values by serial communication, the following items must be set.

Output content

Set the output content as an expression.
Set the output content at [Setup] - [Support] - [Calculation] - [Data].

Output destination

Specify [RS-232C/422] or [USB] at [System] - [Output] - [Data output].

Output format

Set the output format at [System] - [Output] - [Serial output].

For detailed settings, refer to the User's Manual.

ASCII Format

Up to 32 results are output as a data structure of fixed length of up to 12 characters including the sign.

Sign The sign of the measurement value is stored. Plus: 0/Minus: -

Number of digits of integer section "0" is inserted in spaces in the integer section and digits past the decimal

When a value is greater than the preset number of digits, all digits other
than the sign digit become "9".

Data 1: -1000
(-1.000 x 1000)

The value obtained by multiplying the measurement value by 1000 is output continuously as four bytes per
single data item. Minus values are output as 2's complement. Up to 32 results can be output.
The binary format differs from the ASCII format in that data separators, such as field separator or record
separator, do not exist.

Output range: -2147483.648 to 2147483.647

$00 $44$03 $FF$E9 $FF $FC $18

Note

• A value obtained by multiplying by 1000 also is output as the judgment result (JG).

OK: 0

NG: -1000 (-1 x 1000)

• When the measurement value is less than -2147483.648, "-2147483.648" is output.

When the measurement value is greater than 2147483.647, "2147483.647" is output.
