IQH3-FP-V1
Operation
Tries Allowed TA
The tries allowed (TA) parameter sets the number of access attempts during execution of a
read/write operation on a read/write tag.
ParamTyp:
Default:
Value range:
Example
WP1QTA.00.01.01 permits one attempt.
WP1QTA.00.01.03 permits three attempts.
RP1QTA.00.00 reads out the specified number.
Effects of increased number of read/write attempts:
More reliable reading and writing
Longer execution time of a command
Note
To limit the increase in execution time caused by increasing tries allowed, it is recommended to
parameterize the NT cancellation criterion. This will stop the command execution as soon as
the set number of read/write tags has been identified.
Status Frontend ST
The TE parameter can be used to check the read/write device operating status.
ParamTyp:
Default:
Value range
1. Binary combinations are possible
Response to an RP command of the ST parameter:
<Status> <ChanNo> <ST1><ST2> <CHCK> <ETX>
<ST1>
<ST2>
Saved status since the last read-out, 1 byte
Example
RP1QST.00.00 reads out the status of the read/write device.
TA
TA = 2
1 – 10
ST
-
1 .01= Interference from external signals in the usage spectrum, range may
:
be limited.
.02 = Detuning due to surrounding metal
.04 = Excess temperature warning, internal device temperature 80 – 85 °C
.08 = Excess temperature error, internal device temperature > 85 °C
Current status of the read/write device, 1 byte
Saved status since the last read-out, 1 byte
