LCC Events Information

This page details LCC event ID numbers created by the CS-105 or LT-50 or B-106.

These are "well-known events" which means that they don't change from one device to another. The transmission is sent as a byte sequence including "FE FF FF" as written below. 09 00 99 is a designation for the manufacturer ID - Train Control Systems.

Product type identification:

• 09.00.99.FE.FF.FF.00.01 – TCS command station
• 09.00.99.FE.FF.FF.00.02 – DCC Programming Track
• 09.00.99.FE.FF.FF.00.03 – TCS Booster

Broadcast commands:

• 09.00.99.FE.FF.FF.00.10 – Exit Programming Track Mode Immediately. Sending this event cancels the programming track timer (normally 30 seconds after a service mode operation) and returns the command station to regular operation mode. On the CS-105 this turns off the program track output and turns on the mainline and booster output.

Track fault events:

• 09.00.99.FE.FF.FF.01.00 – Track Fault Detected. This device has detected a fault on the mainline output. All devices emit the same event. For per-device information use the configurable events in the per-device Configuration settings.
• 09.00.99.FE.FF.FF.01.01 – Track Fault Cleared. The mainline output on this device does not have a fault anymore. Note that this does not necessarily mean that the track output is enabled.
• 09.00.99.FE.FF.FF.01.10 – Track Fault Due To Extreme Current. The measured current exceeded the second threshold level of short protection.
• 09.00.99.FE.FF.FF.01.11 – Track Fault Due To Overload.  The measured current exceeded the first threshold level of short protection.
• 09.00.99.FE.FF.FF.01.12 – Track Fault Due To Short On Turn-On. The device attempted to turn on the track power, but there was a short circuit on the track, which does not look like a capacitor.
• 09.00.99.FE.FF.FF.01.13 – Track Fault on Programming Track. The current draw of the programming track exceeded the limits specified in the RCN-216 standard. These limits exist to protect the decoder, locomotive and program track in case of a wiring mistake during decoder installation.
• 09.00.99.FE.FF.FF.01.14 – Track Fault Due To Track-to-Common Short. The device detected that one of the tracks is shorted to the Booster Common line.

Track off events:

• 09.00.99.FE.FF.FF.01.21 – Track Turned Off Due To District Off. An LCC Event configured for turning off the track power of this power district was received.
• 09.00.99.FE.FF.FF.01.22 – Track Turned Off Due To Global E-Off. The LCC Event for Global Emergency Off (de-energize) was received.
• 09.00.99.FE.FF.FF.01.25 – Track Turned Off Due To Program Track Operation. The mainline output is turned off, because a programming track operation was started.
• 09.00.99.FE.FF.FF.01.26 – Track Turned Off Due To No Signal. The Booster is not receiving the DCC track signal from the command station.
