Fault DINT Standard Analog Fault mask – controller sets all 32 bits on
connection loss.
• 0000_0000= Connection is
good
• FFFF_FFFF Hex = Connection
has failed
OwnerActive BOOL Owner Active—Indicates that the output has a
controlling owner.
B4
OwnerID BOOL Owner ID—Indicates which owner is active (controlling):
0 = Owner A
1 = Owner B
B5
OwnerAConnected BOOL Owner A Connected—Indicates that Owner A is
connected.
B6
OwnerAClaim BOOL Owner A Claim—Indicates that Owner A is claiming
outputs (COO).
B7
OwnerAReady BOOL Owner A Ready—Indicates that Owner A is Ready to
claim outputs (ROO).
B8
OwnerBConnected BOOL Owner B Connected—Indicates that Owner B is
connected.
B9
OwnerBClaim BOOL Owner B Claim—Indicates that Owner B is claiming
outputs (COO).
B10
OwnerBReady BOOL Owner B Ready—Indicates that Owner B is Ready to
claim outputs (ROO).
B11
RollingTimestamp DINT 16-bit timestamp that ‘rolls’ from 0…32,767 ms.
Compatible with existing PID instruction to automatically
calculate sample deltas.
For more information on the Rolling Timestamp, see
page 23
.
0…32,767 ms
where 1 ms = 1 count
Timestamp DINT[2] 64-bit timestamp value that indicates when any of the 8
channels were last updated with new Output Data.
This value is provided in terms of CIPSync time.
