GE EPM 9650/9800 manual States of the Internal Digital Inputs

then this is the first record recorded after a power-down, reset or download, and it is possible that some transitions were not recorded. If the bit is zero, then monitoring was continuous between the last record and this one.

•The next byte contains the States of the Internal Digital Inputs in the following format:

		Table 6.13: States of the Internal Digital Inputs
				Bits
7	6	5	4	3	2	1	0
Input 8	Input 7	Input 6	Input 5	Input 4	Input 3	Input 2	Input 1

A bit value of 1 means the input is open. A bit value of 0 means the input is closed.

•The next 4 bytes contain the States of the Enternal Digital Inputs in the following format:

		Table 6.14: States of the External Digital Inputs
				Bits
7	6	5	4	3	2	1	0
Input 8	Input 7	Input 6	Input 5	Input 4	Input 3	Input 2	Input 1
		Module 1 External Digital Input States
		Module 2 External Digital Input States

Module 3 External Digital Input States

Module 4 External Digital Input States

A bit value of 1 means the input is open. A bit value of 0 means the input is closed.

•The next byte indicates whether information presented from the External Modules is valid. If the main unit has not yet established contact with an External Module, the information recorded as being from that module is not valid.

	Table 6.15: Valid Information from a Module
			Bits
7	6	5	4	3	2	1	0
Module 1	Module 2	Module 3	Module 4

A bit value of 1 indicates the information from that module is valid. A bit value of 0 indicates the information from that module is not valid.

•The last 2 bytes are unused.
