10-10 LaserSpeed Pro 8500-4 Instruction Handbook:
PROFINET I/O™
For a successful enumeration, the gauge sets the PKW response data as follows:
Bit: 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
Word
2:
Measurement Item Identifier
Word
3:
Measurement Item Access Flags Measurement Item Type
Measurement Item Identifier: identifier to be used with other measurement table services
Measurement Item Type: 0=long, 1=float, 255=unknown
Measurement Item Access Flags: 0x02=read-only
10.3.14 PKW Read Long Measurement (Command Code 13)
This command allows an integer measurement item to be read.
The Profinet IO master specifies the measurement item identifier within the command qualifier. If the refer-
enced measurem
ent item is not an integer, then the response code will be set to “wrong type.”
The gauge will ignore the contents of the PKW Request Data. The PKW Response Data will contain the
signed 32-bit value read from the measurement table.
10.3.15 PKW Read Float Measurement (Command Code 14)
This command allows a floating-point measurement item to be read.
The Profinet IO master specifies the measurement item identifier within the command qualifier. If the refer-
enced measurement item is not floating point, then the respo
nse code will be set to “wrong type.”
The gauge will ignore the contents of the PKW Request Data. The PKW Response Data will contain the 32-
bit floating-point value read from the measurement table.
