Connection

Ferrite cores

Note

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.

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.

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

Connection

ZFX-C Serial Communication Command Reference

• 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.

Input command.

Execute measurement.

Output the processing result.

Receive the measurement result.

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.

HUB

192.168.250.100

IP address

192.168.250.101

IP address

192.168.250.102

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.

Example:

Connection

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.

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.

Example: Data 0 "256.324" and data 1 "-1.000"

Data 0: 256324 (256.324 x 1000)

Data 1: -1000 (-1.000 x 1000)

Note

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

• 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.
