16.1
Connecting to the QX
Cscape connects to the local controller automatically when the serial connection is made. The status bar
below shows an example of a successful connection. This status bar is located in the bottom right hand
corner of the Cscape window.
In general the Target number should match the Local number. The exception to this is when the
controller is being used as a "pass through" unit where other controllers on a CsCAN network could be
accessed through the local controller.
Determine connection status by examining feedback next to Local & Target in the status bar of Cscape.
Local: ###
If a number shows next to Local then communication is established to the local
controller.
Local: No Port
Cscape is unable to access the COM port of the PC. This could mean that Cscape
is configured for a COM port that is not present or that another program has control
of the COM port. Only one Cscape window can access a port at a time.
Subsequent instances of Cscape opened will indicate No Port.
Local: No Com
Cscape has accessed a PC COM port, but is not communicating with the
controller. This typically occurs when the controller is not physically connected.
Local: ??? Unknown communication error. Close Cscape, power cycle the controller and
reopen Cscape with a blank project. Check Local.
Target: #(I,R,D)
If I (idle), R (run), or D (do I/O) shows next to Target number then communication
is established to the target controller.
Target: #(?)
Communication is not established to the target controller. Check node ID of
controller and set Target to match. Make sure local connection is established.
