SPYDER® BACNET® PROGRAMMABLE CONTROLLERS
63-1328—05 4
Universal Input (UI) Circuits
See Table 2 for the UI specifications:
Hardware (PUB6438S, PUB6438SR,
PVB6436AS, and PVB6438NS)
CPU
Each controller uses a pair of microprocessors. The first is a
16-bit Texas Instruments MSP430 family microprocessor that
is used to manage the Inputs, Outputs and Control. The
second is a 32-bit ATMEL ARM 7 microprocessor that
manages communication for the Spyder BACnet.
Memory Capacity
Flash Memory: 372 kilobytes. The controller is able to retain
Flash memory settings for up to ten (10) years.
RAM: 72 kilobytes
Hardware (PVB0000AS, PUB1012S,
PUB4024S, PVB4022AS, and
PVB4024NS)
CPU
Each controller uses a 32 bit ATMEL ARM 7 microprocessor.
Memory Capacity
Flash Memory: 512 kilobytes. The controller is able to retain
Flash memory settings for up to ten (10) years.
RAM: 128 kilobytes
Controller Status LED
The LED on the front of the controller provides a visual
indication of the status of the device. When the controller
receives power, the LED appears in one of the following
allowable states, as described in Table 3.
BACNET STATUS LED:
The LED on the front of the controller, between the BACnet
MS/TP terminals and MAC Address DIP Switches, provides a
visual indication of the BACnet MS/TP communication status.
When the controller receives power, the LED appears in one
of the following allowable states, as described in Table 4.
