C-115
C.5.3. CallBackTimeoutSec
This Global parameter specifies the amount of time in seconds that the controller will wait
before generating a task fault if there is no response to a callback from the Frontend.
C.5.4. CompatibilityMode
This global parameter, allows the programmer to change the behavior of the UNIDEX
600 back to the “original” or legacy behavior, when such is required. This parameter is
provided to allow users to run CNC programs written for older versions of the UNIDEX
600 MMI.
The parameter is a bit-mapped value, where each bit toggles the behavior from the
current, or default behavior, to a previous behavior that was defined in older versions. Bit
#0 is the least significant bit. The version number in the chart indicates the first version of
the software that had this change in behavior.
Table C-20. Compatibility Chart
Bit # Hexadecimal Value Data Changed Version Old Behavior that is Activated
0 0x1 1/15/99 5.90 G2 / G3 are not modal
1 0x2 5/6/99 6.98 Old Style Contouring
2 0x4 8/1/99 6.103 Handling of “within tolerance” radius errors by a
linear jerk to start point, using the radius specified
from the endpoint.
3 0x8 8/1/99 6.103 Non-averaging end-of-move non-integer time
portions, into proceeding move slices.
4 0x10 9/1/99 6.106 Convert G43/G47/G65/G66 to User Units
5 0x20 Reserved
6 0x40 12/21/99 6.112 Old style Link Moves for Normalcy Motion
C.5.4.1. Move Calculation Averaging
Setting this bit to 1, True, defines non-averaging end-of-move non-integer time portions,
into proceeding move slices. Otherwise, the fractional move distance is averaged over the
entire move.
C.5.4.2. Radius Error Bit 2
Handling of “within tolerance” radius errors by a linear jerk to start point, using the radius
specified from the endpoint. Setting this bit to one restores this mode, otherwise, a new
center point is calculated, for errors less than the MaxRadiusError task parameter.
C.5.4.3. Convert G43/G47/G65/G66 to User Units
Software versions prior to 6.106, assumed that that the distance units for the parameters to
the G43 / G47 / G65 / G66 commands were in inches. Setting this bit to 0, defines this
state. Otherwise, if the bit is 1, the parameters are assumed to be in the state defined by
the G70 / G71 modal commands.
This bit will default to one, True, on new software installations. On updates of older
systems this bit will be remain zero, to maintain compatibility.
