INPUT parameters
Variable
Description
ASM_address
Logical base address of the ASM. This address must match the "start address" of the ASM in HW
Config of the SIMATIC Manager. Remember that this address has nothing to do with the PROFIBUS
address which is set on the ASM or the ET 200M.
Number of the MOBY channel which is to be used
ASM type
Value range
ASM_channel
ASM 475, 452
ASM 454, 754, 854
ASM 473, 850

command_DB_
number
Number of the data block in which the MDS command is
specified
command_DB_
address
Address within the "command_DB". The next MDS
command starts at this address. "command_DB_number"
and "command_DB_address" form a data pointer to the
next command (see Section "Configuration scheme").
These INPUT parameters can be
changed whenever ready = 1. An init_run
does not need to be executed after
changing these parameters.
MDS_control turns on/off the presence check or the MDS control on the ASM (see Section
"Presence check and MDS control").

Presence check is off. The variable ANZ_MSD_present doesn't indicate
a valid value.
Presence check is on. MDS control is off. The variable
ANZ_MDS_present indicates an MDS is the transmission window of a
write/read device.
Presence check is on. MDS control is on, and control takes place with
the presence check of the MDS. The NEXT command must be sent to
the ASM each time an MDS is processed.

ECC_mode
Turns ECC mode on (true) or off (false). Remember that ECC mode can only be used with MOBY I.
RESET_long
The init_run command transfers all INPUT parameters to the ASM. This bit must be set to TRUE
when MOBY U/D or RF300 are used (MOBY_mode = 5).
