GE EPM 9650/9800 manual Type F6 High Speed Input Delta and Current State, Bytes

3.6: Type F6 High Speed Input Delta and Current State

Length: 1 Register (2 bytes)

This register has two bytes. Each byte has eight bits. The bits in each byte are associated with the 8 High Speed Inputs, the least significant bit with Input 1, through to the most significant bit with Input 8.

The most significant byte contains Delta information about High Speed Inputs, the least significant byte contains the Current State of the High Speed Inputs. For Delta bits, a bit value of 1 means one or more were noticed on this input during the last cycle, a bit value of 0 means no changes were noticed on this input during the last cycle. For Current State bits, a bit value of 1 means the input is open, a bit value of 0 means the input is closed.

Example:

Register 00118, 1 cycle High Speed Input Delta and Current State, might contain the following data.

Address								00118
Value								0461H
Bytes					04H								61H

Meaning	_	_	_	_	_	Change	_	_	Clsd	Opn	Opn	Clsd Clsd Clsd Clsd				Opn

Interpretation Inputs 7, 6 and 1 are now open and Input 3 changed state at least once during the last cycle.
