Meaning
Global parameter of type "IID_HW_CONNECT" to address
the communication module and reader and to synchronize
the instructions. This parameter is located in the varia-
bles of the type "IID_DATA_ *". "HW_CONNECT" must
always be transferred to the instruction to address the
relevant channel/reader.
TRUE = Triggers a new command
Before starting you need to set the command and the
corresponding parameters in the memory linked to
"CMDREF".
TRUE = Repeating the command currently being execut-
ed or the next command to be executed by the communi-
cation module
TRUE = Cancellation of the command currently pro-
cessed on the communications module
TRUE = Communications module executes a restart and
is re-assigned parameters
Number of commands in the parameter "CMDREF"
Selection of the command to be executed "CMDREF";
0 ⇒ 1. command, ...
The value of the "CMDSEL" parameter can never be
higher than the value of the "CMDDIM" parameter.
Command field
The field can hold up to 10 commands. The commands
are complex variables of the type "CMD_STRUCT". You
can find more information on "CMDREF" in the section
"Commands of the Ident profile (Page 72)".
Reference to global memory area for send data.
The memory area can be shared with other instances of
the instruction. The value "n" of the individual instruc-
tions is variable and can range in size from 10 bytes ... 32
KB.
Reference to global memory area for receive data.
The memory area can be shared with other instances of
the instruction. The value "n" of the individual instruc-
tions is variable and can range in size from 10 bytes ... 32
