Meaning
Global parameter of type "IID_HW_CONNECT" to address
the communication module and reader and to synchronize
the blocks. This parameter is located in the variables of the
type "IID_DATA_ *". "HW_CONNECT" must always be
transferred to the instruction to address the relevant chan-
nel/reader.
TRUE = triggers a new command
Before starting you need to set the command and the corre-
sponding parameters in the memory linked to "CMDREF".
TRUE = Repeating the command currently being executed
or the next command to be executed by communications
module
TRUE = Cancellation of the command currently processed
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";
1 ⇒ 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 66)".
Reference to global memory area for send data.
The memory area can be shared with other block instances.
The value "n" of the individual blocks is variable and can be
up to 10-32 KB in size.
Reference to global memory area for receive data.
The memory area can be shared with other block instances.
The value "n" of the individual blocks is variable and can be
up to 10-32 KB in size.
