Using SCANport Capabilities D–5
Publication 1397-5.0 — June, 2001
You can specify how you want to be notified if SCANport loses the
connection to a port.
Then:
Set appropriate bit in LogicMask (p. 207) corresponding to the
SCANport device number or set Control Logic to enabled.
Clear appropriate bit in Logic Mask (p. 207) corresponding to the
SCANport device number, or set Control Logic disabled.
If you want a communications
loss to be:
Reported as a fault
Ignored
The following table specifies which bit represents a device:
To specify this device: Set this bit:
SCANport device 1
SCANport device 2
SCANport device 3
SCANport device 4
SCANport device 5
SCANport device 6 1
2
3
4
5
6
For Example: If you want a fault condition reported when
communication is lost with device 3, you need to set bit 3 of Logic
Mask.
NOTE: When a device is configured to NOT cause a fault upon
disconnection, this device cannot control any functions in the Drive.
The SCANport I/O image provides the interface between the
SCANport devices and the Drive. The SCANport I/O image is used
to transfer realtime data in the same way as the PLC image is used.
The devices on SCANport allocate the SCANport I/O image so
multiple devices can use different sections of the image.
To view the values in the I/O image table, use parameters 226
through 233 for input and 234 through 241 for output.
