5.6.1 Event Programming Overview
Event programs are composed of signal test and action commands stored in
a non-volatile event table. The MCC-545A stores the event table in battery-
backed-up-RAM. The MCC-545B and MCC-545C store the event table in
FLASH memory.
The operator enters these event commands into the MCC-545C. The MCC-
545C scans the event table at power-up/reset, and then at every 1/16
second clock interval. It looks for the occurrence of defined events. When
a defined event occurs, the MCC-545C invokes the corresponding action
commands. The capability includes:
• Testing discrete input lines
• Setting or clearing a discrete output line
• Testing Analog input values
• Transmitting brief text messages
• Execute a local command of up to 40 characters
• Transmitting vehicle position reports
• Transmitting marker drop reports
