b. CsCAN
Network
When used with a Back Pack option, the QX 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 QX and require no external or
additional modules.
Figure 2-3 – Pass Through Function (Available in CsCAN Networks Only)
The QX features the ability to pass through programming commands. When attached to an QX serial
port, a programming package (i.e., Cscape) can access other QX 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 QX unit) can program all QX or other QX/RCS
units on the CsCAN network. When several QX models are networked together to achieve a specific
purpose, the system acts like a large parallel-processing controller.
c. Cscape
Software
QX hardware is programmed with a Windows-based PC application called Cscape (HE500OSW232).
Cscape (pronounced “see-scape”) stands for Control Station Central Application Programming
Environment. Provided there is one serial connection to one node on the network (i.e., CsCAN
Network), the operator has control over the entire system. The operator can upload, download, monitor
and debug to any node on the network.
This application can be used to program, configure, monitor and debug all aspects of the QX unit. It is
used for programming QX OCS ladder logic, programming user displays for the QX OCS, configuring the
network for global digital and analog data, setting system-wide security and monitoring controllers in the
system.
2.3.2
Back Pack I/O Interface (BP41, BP43)
The Back Pack I/O Interface (BP) adds comprehensive I/O functionality to the QX. The BP uses a
Fiber
Optic Extension System ( FOX) to extend a high-speed QX backplane in a CsCAN network and enables
SmartStack I/O Modules to be mounted several meters from the QX. The FOX significantly increases the
number of SmartStack I/O modules supported by one QX. Remote SmartStix I/O can also be used.
When using BP43, an additional High Speed I/O function is provided.
