STATUS REGISTERS
To program the PEL-200 Series effectively, the
Status Register structure needs to be understood.
This chapter explains in detail the structure of the
status registers.
Status Register Overview
Description
The status registers are used to determine the
status of the electronic load. The status registers
maintain the status of the protection conditions,
load conditions and channel conditions of the load
modules.
The PEL-2000 series have a number of register
groups:
Channel Status Registers (one for each channel)
Channel Summary Registers
Questionable Status Registers
Standard Event Status Registers
Status Byte Register
Service Request Generation Register
The structure of the status registers is shown on
the next page.
