ZFX-C is a machine vision sensor with built-in LCD monitor, it can communicate with PC or programmable controller via serial interface.
This manual provides the command reference for the Omron ZFX-C20 vision sensor, describing how to communicate with the device via USB, RS‑232C/422, or Ethernet. It includes information on connection methods, communication parameters, and command structures needed for integration with external systems.
The document outlines the supported communication speeds, data formats, and protocol details, as well as practical guidance for wiring, driver installation, and network configuration. It also lists restrictions on multi‑PC or external LAN connections and provides example command sequences.
| USB speed | 12 Mbps (Full speed, USB2.0 compliant) |
|---|---|
| RS‑232C/422 maximum speed | 115200 bps |
| RS‑232C/422 data length | 7 bits, 8 bits |
| RS‑232C/422 parity options | None, even, odd |
| RS‑232C/422 stop bits | 1 bit, 2 bits |
| Ethernet transmission mode | Peer to Peer |
| Data delimiter | CR, LF, CR+LF |
| Transmission code | ASCII (binary optional for measurement values) |
Use a USB cable (ZFX‑XUSB) to connect the controller to the PC, attach the supplied ferrite cores, and install the USB driver the first time you use the interface.
The RS‑232C/422 interface supports 9600, 19200, 38400, 57600 and 115200 bps communication speeds.
No. Communications with the controller from outside the LAN or between two PCs are not possible.
Assign each controller a distinct IP address (e.g., 192.168.250.100) and ensure no duplicate addresses are used.
