Detailed Product Descriptions
2.3.1 QX751 Base
a. Features
The QX751 combines several desirable functions in one compact package. Each unit is a highly
integrated operator interface and controller with expandable I/O and networking capabilities have
standard features consisting of the following:
• Color Touch, resistive screen (TFT)
• 24 VDC powered
• RS-232 / RS-485 Serial Ports
• Integrated
Bezel
• Real-Time
Clock
• Flash Memory
• Removable Media memory for easy field upgrades
• System Key and Configurable Function Keys
• Ethernet (10/100 MHz)
• Back Pack Expansion Connectors (refer G required)
b. CsCAN Network
When used with a Back Pack option, the QX751 has the feature of CsCAN peer-to-peer
networking. (CsCAN is pronounced “see-scan”). CAN-based network hardware is used in the
controllers because of CAN’s automatic error detection, ease of configuration, low-cost of design
and implementation and ability to operate in harsh environments. Networking abilities are built-in
to the QX751 and require no external or additional modules.
Figure 2.3 – Pass Through Function (Available in CsCAN Networks Only)
The QX751 features the ability to pass through programming commands. When attached to an
QX751 serial port, a programming package (i.e. Cscape) can access other QX751 units or any
other QX/RCS unit connected to a CsCAN network by passing the programming command
through the serial port to the network port. One Cscape package (connected to one QX751 unit)
can program all QX751 or other QX/RCS units on the CsCAN network. When several QX751
models are networked together to achieve a specific purpose, the system acts like a large
parallel-processing controller.
