Module E11
Status: 01/2010 Radio Frequency Identification (RFID) with SIMATIC S7-300F-2PN/DP and
RF180C
Input Parameters of the UDT11
The user has to enter these variables during configuration (exception: command_DB_number/
command_DB_address).
It is not necessary to change or poll these parameters during the entire execution time.
Please note that before the new setting takes effect, "init_run“ has to be performed after an INPUT
parameter is changed (refer to chapter "Programming Restarts and Warm Restarts").
Variable Description
IM Address IM’s logic base address. This address has to match the IM "start address“ in HWConfig of the SIMATIC
Manager. Please note that this address has nothing to do with the PROFIBUS address that is set at the
IM or the ET200M.
Number of the MOBY channel that is to be used for processing:
ASM Type
Value Range
IM Channel
IM475, 452, 456,RF170C
IM 454, 754, 854
ASM 473, 850
1,2,
1,2,3,4
1
command_DB_
number
Number of data block where the MDS command is specified
command_DB_
address
Address within the "command_DB“. The next MDS command starts
on this address. "command_DB_number“ and
"command_DB_address generate a data pointer to the next
command (refer to chapter "Configuration Scheme“).
These INPUT parameters can
be changed if ready = 1.
After a change of these
parameters, init_run does not
have to be performed
Please note:
The input parameters command_DB_number and command_DB_address are to be changed only if
ready = 1. After changing these parameters, init_run does not have to be performed.
MDS_control switches the attendance check or the MDS control on or off on the IM (refer to chapter
"Attendance Check and MDS Control“).
Value
MDS Control
IM Type
0 Attendance check is switched
off. The variable
ANZ_MSD_present does not
indicate a valid value
All
1 Attendance check is switched
on. The MDS control is switched
off. The variable
ANZ_MDS_present indicates
an MDS in the transfer window
of a reader
All
MDS Control
2 Attendance check is switched
on. The MDS control is switched
on and happens by means of
the attendance check of the
MDS. The NEXT command has
to be sent to the IM after each
MDS processing.
454
ECC_mode Switches on the ECC mode on (true) or off (false). Take note that the ECC mode is permitted only for
MOBYI.
RESET_long With the command init_run, all INPUT parameters are transmitted to the IM. For MOBY U/D or RF300
operation, this bit has to be set to true (MOBU_mode = 5)
