The Power Control function calculates which zone should be currently active. The Power Control
begins in the ON state and continues with a full On Time and then goes to the OFF state for the full Off
Time.
2.2.1.7 Report By Exception (RBX) Alarming
The RBX Alarming function (added for Version 1.05 and greater) allows a communications port to be
set up to enable the FloBoss to contact the host computer when specified alarm conditions exist.
2.2.2 Processor Board Description

Figure 2-1 shows a view of the processor board mounted on the door of the FloBoss 407 case and the
termination board mounted in the FloBoss 407 case.
The FloBoss 407 derives processing power from a NEC V25+ microprocessor. The NEC V25+ is a 16-
bit CMOS microprocessor featuring dual 16-bit internal data buses and a single 8-bit external data bus.
The unit can address up to one megabyte of memory and features high-speed direct memory access.
The processor board has 512 Kbytes of static random access memory (SRAM) for storing interrupt
vectors, Function Sequence Tables (FSTs), ROC displays, alarms, events, user program data, and
history data.
