RCX

Our OCS product integrates the PLC and HMI in One Product. But there are times when the customer also requires a more traditional approach. RCX is the only X-series product that does not include a display, yet keeps all the benefits of an Ethernet enabled OCS.

  • constructed with a plastic chassis and supports Plastic SmartStack I/O for local I/O (up to 4 modules)
  • logic engine supports 16k / 256k logic, scanned at 0.2mS/K, with 32Kb of register memory and a Start/Stop pushbutton
  • features a MicroSD memory slot, one RS-232 port, one RS-485 port, one CsCAN port and a full 10/100 Ethernet port (HECX251 only)
  • the Ethernet port supports HTTP web serving, FTP file transfers, SmartRail Ethernet I/O, Modbus/TCP Master/Slave, EGD and more

Overview

CONTROL

The RCX has a ladder-based control engine that is powered by processor with 256KB logic memory. This processor provides speed comparable to most mid-sized PLCs and is exactly the same as used in the XL6 family.

INPUT/OUTPUT

Because of the multiple ports on the RCX, it is capable of handling all Horner I/O expansions including: SmartStack, SmartRail (built-in Ethernet Port), SmartStix and SmartBlock (CsCAN port) & SmartMod (Modbus serial).

The SmartStack I/O expansion system allows the RCX to use both digital and analog I/O boards. Up to 4 I/O boards may be stacked onto a single RCX unit, giving you flexibility with various I/O combinations. Together with Ethernet, CAN and Serial I/O capabilities RCX can use all I/O combinations possible.

OPERATOR INTERFACE

Designed to be used with or without a seperate operator interface. Horner offers its TIU Range (or another OCS with a display) that can be easily configured to communicate with the RCX.

RELAY LADDER LOGIC

Cscape software provides graphical ladder diagram programming (IEC-1131 compliant) . Design engineers and end users will enjoy reduced development time with a straightforward approach to programming that integrates logic, and networking into a single solution operating in the Windows environments.

Remote I/O

Remote I/O available for this product includes:

CsCAN Based I/O
Modbus RTU Based I/O

Networking

A benefit of the RCX is that it can connect to other Horner devices that use our CAN based protocol CsCAN (majority of products). This leaves the other communication ports (Ethernet and 2 serial ports) free to communicate with a device of your choice.
