GE EPM 9650/9800 manual Type F39 Confirmed Polled Relay States

3.39: Type F39 Confirmed Polled Relay States

Length: 1 Register (2 bytes)

This register has two bytes. Each byte has eight bits. The bits in these bytes are associated with the 16 Relays, the most significant byte with Relay 1 through to the least significant bit of the least significant byte with Relay 16.

A bit value of 1 means the relay was energized (connected to Normal Open) when last polled, a bit value of 0 means the relay was de-energized (connected to Normal Close) when last polled. These states may not be current on the relays, since operations may have occurred since the last poll.

Example:

Register 06011, Confirmed Polled Relay States 1-16, might contain the following data:

Address								06011
Value								0461H
Bytes				04H								61H
Bits	0	0	0	0	0	1	0	0	0	1	1	0	0	0	0	1
Point	0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15
Relay	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16
State (NO/NC)	NC NC		NC NC NC NO NC NC NC NO NO NC NC NC NC NO
Interpretation		Relays 6, 10, 11 and 16 were energized when last polled, all others were de-ernergized.

3.40: Type F40 Valid Flags for Confirmed Relay States

Length: 1 Register (2 bytes)

This register has two bytes. Each byte has eight bits. The bits in these bytes are associated with the 16 Relays, the most significant byte with Relay 1 through to the least significant bit of the least significant byte with Relay 16.

A bit value of 1 means the confirmed states in Confirmed Polled Relay States register (06011) are valid, a bit value of 0 means the confirmed states have not yet been polled.

Example:

Register 06012, Valid Flags for Confirmed Relay States, might contain the following data:

3-28
