Name
Status register of the smart camera. Each bit of this register represents a
differrent state item.
See Status: Camera Status Register (16-bit) on page 3-15 for bit de-
scriptions.
This 16 bit word value reflects back to the PLC the value that the PLC
wrote to the output assembly ECHO register. The PLC can verify the out-
put assembly has been written to the smart camera when this value
matches the written value.
When Status.ExeCmdAck gows active in response to Control.ExeCmd,
CmdCodeRslt contain the data returned from the command invoked by
CmdCode.See CmdCodeRslt (32-bit) on page 3-16 for definitions.
When Status.ExeCmdAck gows active in response to Control.ExeCmd,
CmdRet contains the data returned from the command invoked by Con-
trol.CmdCode.See CmdRet (32-bit) on page 3-16 for definitions.
Resurved for future use.
Device State register. Depending on the current state of the smart cam-
era, certain STATUS and CONTROL features may or may not be opera-
tioned.See State (16-bit) on page 3-16 for definetions.
Each bit reflects the state of virtual IO point. The least significant bit re-
flects vio point 145, the most significannt ite vio point 160.
Resurved for future use.
Each bit represents a boolvalue. the least significant bit of byte 20 reads
the value of bool1. The most significant bit of byte 27 reads bool64.
Each pair of sequential bytes represents a 16 bit signed integer value.
the20 bytes represents 10 integers.
From bytes 28 & 29 for the value of int1 through bytes 46 & 47 for the
value of int10.
Each group of 4 bytes represents a 32 bit signed integer value.
the 40 bytes represents 10 long integers. From bytes 48 -51 for the value
of long1 through bytes 84-87 for the value of long10.
Each group of 4 bytes represents a 32 bit signed integer value.
the 40 bytes represents 10 floating point values. From bytes 88 -91 for
the value of float1 through bytes 124-127 for the value of float10.
These 96 bytes can store a string of up to 92, 8 bit characters, with the
first 4 bytes containing the length value.
Each of these 32 bytes group can store a string of up to 28, 8 bit charac-
ters, with the first 4 bytes containing the length value.
