SCATS 6.9.1: What’s new – cont’d
The major changes in this version are:

• Improved controller fault management.
• New variation routines for resetting the state and implementing
a logical AND between tests.
• Ability to import the SCATS host licence name and licence
details from the licence file into the two configuration programs

SCATS 6.9.1: New Features - 1
Time Gain Changes
• The rule introduced in v6.6.3.2 that time gain could only be accepted
from phases that were allowed to gap has been removed!
• A sanity test is now applied to time gain at the end of each phase that
fixes TG build-up observed in Master-Isolated mode and skipping of
the stretch phase.
• Time can now be gained from skipped phases when a dwell is applied.
SMUG 2013

SCATS 6.9.1: New Features - 2
Walk monitoring – includes secret walks
• An RPS request is now sent to all controllers every second to get the
demanded walks and the active walks.
• Site diagnostic monitor (IDM) files now show when a walk ended
rather than when a walk termination request was sent.
• The capture of the intersection status when an SC, LC or IH alarm is
generated will also show secret walks (eg More… in Access).
SMUG 2013

SCATS 6.9.1: New Features - 3
ST alarm (NXP) review
• The failure of a controller to answer an NXP/CLP message within 8
seconds now generates Fallback instead of an ST alarm.
• An ST is generated only when no messages at all are received for 8
seconds.
• Generate an ST alarm if NXP reply is 16 seconds late – TS mode
• The processing of the Special Facilities for an intersection (Y-, Z-, Z+,
Z1-6, XSF, RSF) are now done for intersections that are not
communicating as they could be used by Variation Routines.

SCATS 6.9.1: New Features - 4
Improved controller fault log management
• SCATS can now detect a deadlock when a controller fault log is
being automatically retrieved. The fault is logged and SCATS will
retry after 60 seconds which allows RAM/IMAP changes to be saved.
• The controller log can now be saved to the SCATS log file when a
controller has a WD alarm.
• The AL/ command in SCATS Terminal now resets the flag that allows
an RLE fault (Read Log Entry) to be logged.
SMUG 2013

SCATS 6.9.1: New Features - 5
Variation Routines
• New variation routine to AND (VR18), implemented.
- When "test" routines follow each other, there is an implied AND between the
routines.
- When an OR is used (VR19), as in A OR B AND C, you get A or (B AND C).
- If you want (A OR B) AND C you must use VR18 for the AND.
- VR18 also allows (A OR B) AND (C OR D)
• VR83 (Test an SA for congestion) now compares the user supplied
DS against the DS from the SI, not the split plan vote DS.
SMUG 2013

SCATS 6.9.1: New Features - 6
Variation Routines
• A variation routine (VR10) has been added to reset the variation
routine state to true
• It is now recommended that you use VR10 instead of VR19 (the
OR routine) if you need to reset the state.
• The Variation Routine Usage dialogue now includes the stop routine
(VR0) and longer descriptions.
SMUG 2013
11
SCATS 6.9.1: New Features - 7
Variation Routines
• All the variation routines are
now shown in the Variation
Routine Monitor dialogue with
an icon and description. The
icon identifies the type of
variation routine or whether it
has been skipped, bypassed or
is unknown. A shortcut menu
provides a legend for the
meaning of the icons.

SCATS 6.9.1: New Features - 8
SCATS Flags
• All flags except MSS can be locked or trimmed to an ON state or an
OFF state.
• Each flag is managed separately.
• A trim cannot be applied if the flag is locked.
• SF and XSF locks no longer require a split plan lock to be applied
(i.e. no PL=0#! Needed)
• SF and XSF trims clear on a split plan change.
