Siemens S7-300F-2 PN, DP manual Variable Description

Industry Automation and Drive Technologies - SCE

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.
IM Channel	Number of the MOBY channel that is to be used for processing:
	ASM Type	Value Range
	IM475, 452, 456,RF170C	1,2,
	IM 454, 754, 854	1,2,3,4
	ASM 473, 850	1
command_DB_	Number of data block where the MDS command is specified	These INPUT parameters can
number		be changed if ready = 1.
command_DB_	Address within the "command_DB“. The next MDS command starts	After a change of these
address	on this address. "command_DB_number“ and	parameters, init_run does not
	"command_DB_address generate a data pointer to the next	have to be performed
	command (refer to chapter "Configuration Scheme“).

	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	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	All
			off. The variable
			ANZ_MSD_present does not
			indicate a valid value
	1		Attendance check is switched	All
			on. The MDS control is switched
			off. The variable
			ANZ_MDS_present indicates
			an MDS in the transfer window
			of a reader
	2		Attendance check is switched	454
			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.
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)
