Table 3- 52 Input parameter
Input parameter
Data type
Default value
Meaning
HW_CONNECT HW_CONNECT -- Own data type for physical addressing of communications
modules and readers and for synchronizing the blocks used
for each reader.
The addressing is as described in the section "
Setting the
"IID_HW_CONNECT" data type (Page 17)".
EXECUTE BOOL FALSE TRUE = triggers a new command
Before starting you need to set the command and the corre-

module
SRESET BOOL FALSE TRUE = Cancellation of the command currently processed
on the communications module
INIT BOOL FALSE TRUE = Communications module executes a restart and is
re-assigned parameters
CMDDIM
INT
10
Number of commands in the parameter "CMDREF"
CMDSEL INT 0 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.
CMDREF ARRAY[1...n] of
CMD_STRUCT
-- Command field
The field can hold up to 100 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 77)".
TXREF ARRAY[1...n] of
BYTE
-- 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 32 KB in size.
RXREF ARRAY[1...n] of
BYTE
-- 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 32 KB in size.
