QLength: 1 Register (2 bytes)
QThis 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.
Abit 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:
Point
Bits
Bytes
Relay
State (NO/NC)
Interpretation Relays 6, 10, 11 and 16 were energized when last polled, all others were de-ernergized.

QLength: 1 Register (2 bytes)
QThis 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.
Abit 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:
