Sylk accessory model support and how to use them ( i.e Zeleny and Zelix support) Additional Sylk devices like actuators and the C7400S enthalpy sensor are now supported in all models of Spyder shipped from the factory after date code 1220 (Spyders that pre-date this can be re-flashed to support these new devices). To configure these devices, Go to the Terminal Assignment view and click the Add Sylk Device button and choose the appropriate device from the pulldown. Then drop the PhysicalPoint on the wiresheet (AO for an output value like an actuator, UI for an input value like a sensor) and then configure that block for a type of FixedSylkInput or FixedSylkOutput:

The tool will then automatically assign that physical point to a Sylk pin and the block will now show that information on the block, and the terminal assignment view will also show that point which can also be re-assigned if the default assignment is not desired.


The screen above is arranged to show information that is an input to the Spyder on the left and information that is an output to the Spyder on the right. In other words, points on the left are information the Spyder receives from the Sylk device, points on the right are things that Spyder uses to command the Sylk device.
Calibration and Diagnostics is not available for physical I/O that has been assigned a type of FixedSylkInput or FixedSylkOutput
There are three models of Sylk I/O:
Currently the only Spyders capable of supporting Sylk I/O devices are the Spyder with relay devices (PU*6438SR)
Below is a wiresheet with more physical points than a Spyder has (note the tool allows the user to drop an unassigned I/O, denoted by the red circle and slash.


When the model of Spyder is changed and Sylk devices have been configured, the associated Sylk devices may be affected since some Spyders support Sylk devices which others do not (for example PUL6438S does not support Sylk I/O, but a PUL6438SR does). After the model has been changed, the tool will automatically remove any unsupported Sylk devices and any points previously configured for that device will be shown as unassigned in the wiresheet. If a Sylk device model has been changed, then any points not supported on the new model will be shown as unassigned in the wiresheet.
