GDW Refresh Rate 1/10s: 0
The rate at which values on a GDW page are redrawn
Low Scan Rate 1/10s: 100
The speed of this Scan rate at which values are obtained over the wire.
Medium Scan Rate 1/10s: 20
The speed of this Scan rate at which values are obtained over the wire.
High Scan Rate 1/10s: 10
The speed of this Scan rate at which values are obtained over the wire.
Ultra High Scan Rate 1/10s: 5
The speed of this Scan rate at which values are obtained over the wire.
Trend Grid Segments: 0
Puts in horizontal lines to divide into this number of segments
(for example, 4 = divide into quarters)
*Comms Back Off Multiplier: 30
If a value can't be accessed over comms, then this number is multiplied by the scan rate of the parameter and used as a 'delay' factor before retrying.
The values for Low/Medium/High Scan Rates are specified above. Which of these is being used for a given parameter is defined in Dynamic Attributes.
When any two parameters from an instrument cause consecutive timeouts, that whole 'instrument' is treated as gone (all parameters revert to N/R), and a special 'primary parameter' (usually the Process Value) is requested. If this primary parameter can be acquired over comms, then the whole instrument is returned to active comms use. However, if the Primary Parameter still times out, it is 'backed off' as before. Then (Comms Back Off Multiplier x Scan Rate) seconds later, the primary parameter *only* is retried and the process, detailed above, starts again. The effect of this is that instruments that are switched off will cause very little effect on comms to other daisy-chained instruments that are still communicating.
Disable Edit Mode: Disabled
Used to Disable access to Edit Mode.
Hide Status Bar: Disabled
Used to Hide the Status Bar to maximize screen space.
Single Click Alter: Enabled
In Runtime Mode this is used to determine if values can be changed by just a single-click or a double-click. This is useful if Maximized is disabled on the Startup tab (see below), and there are other windows on the screen to click between, as single clicking on a variable by accident will popup the variable change box.
Disable COM Port Settings Popup: Disabled
Used to Disable COM Port Settings box
Archive/Restore Directory:
This defaults to the folder that SpecView is installed in, but it can be set to any drive and folder.
*Trend DP Override:
Allows the number of decimal places used by Trend Charts to be set.
Line Writer DP:
The Line Writer is either a button or Strategy Controller action type. This specifies the number of decimal places to be used.
Parameter List
Parameter List PPS: 15
When the Instrument View's parameter list button is clicked in Runtime Mode, this is the number of values read per second (Points Per Second) in order to display the parameter list.
Read All Parameter Values: Disabled
This forces SpecView to read ALL the parameters in the Variables List (or Parameter List). When unchecked only the visible parameters will be read, significantly improving the update rate on those parameters.
NOTE: * indicates: A change will not take effect until next entry to Runtime Mode
