New Features:


S-LX:TDM 1024

  • The S-LX now supports monitoring of Westronic TDM1024 systems.
  • Much like our other TDM monitoring solutions, Digital data output, back-and-forth between "field" and "office" is monitored from the system serial port.
  • The S-LX system makes a fail-safe connection between Modem and CPU as shown below.
  • Both CPU's are monitored in each installation.

System Overview

Connection Overview

The S-LX will report

  • Digital State Changes for all I/O  channels on one of the CPUs (It will pick one CPU at random if both CPUs are operational.)
  • The connection status of "office" and "field" links on both CPUs. (So it is always possible to determine the health of both CPUs)

T-LX

The T-LX loggers now support capture of data using a USB connected "Picoscope 5000". The following features are defined:

  • Data is captured on receipt of a trigger
  • A Trigger is defined as the receipt of an event on a specified channel (determined by regular expression, e.g. ".*Pulse Input Handler detected.*")
  • The sample rate is configured in the data logger. (1kHz..100kHz - default 10kHz)
  • Data is collected for a specified duration with a defined pre-trigger (maximum 20000 samples, e.g. 2 seconds pre-trigger, 2 seconds data collected)
  • Channels A thru D can be collected simultaneously according to configuration (note: when using USB power only channels A & B are available)
  • The Picoscope will measure the major frequency of a waveform signal (e.g. square wave) and report this in Hz
  • The Picoscope will report the peak voltage measured on a signal.
  • Periodic capture of Picoscope traces can be scheduled using the TimeOfDay channel.
  • Derived channels may be created using simple numeric expressions. For example, a TrackLink pulse count can be converted to distance using an expression such as "='.*Pulse2'*32.47621406/1000+13.5".

Captures can be viewed in Centrix using existing functionality (Centrix | Inspect | Captures)

The T-LX will now decode the "Tracklink III pulse count" channel

Existing Syslog message:

Decoded Pulse count channels (from event inspector):

General

  • Additional message queue validation is performed by the logger on restart to improve recovery on unexpected power down (and restart).

Bug Fixes

S-LX : S2 TDM

  • TDMs with multiple housings require a housing adjustment be applied. This can be performed for office & field ends independently.
  • TDMs decode correctly identify all bits from a specified card and housing.
  • Data streams bugix: Large OUTPUT_DATA messages could previously incorrectly tag the digital channel.
  • The S2 decoder has been updated to prevent an issue causing the following to be seen in the events list:

    The "Connected:S2 Field" channel is now correctly marked inactive when the serial link transitions from "active" to "inactive".

SA-SSI

  • Resolved issue with SSI data loggers generating excess data if the Ident value has not been set (it is strongly advised that the ident correctly configured so that full statistics can be generated).

General

  • Fixed a small resource leak affecting S-LX devices.
  • Centrix connection code watchdog update
