The "COM PROFIBUS" program is required to use the FM 458-1 DP
application module with the communications expansion module
EXM 448 as master. It runs on a PC under Windows and generates a
COM database.
The generated database can also be loaded via
PROFIBUS (with PC PROFIBUS card CP5411, CP5511 card)
or
COM1/2 interface of the PC and RS-232 parameterizing/diagnostics
interface with the "SS52load" driver program
in the EXM 448.
COM PROFIBUS must be additionally ordered, if EXM 448 is to be
configured as master.
Designation Order No.
COM PROFIBUS 6ES5 895-6SE12 (German)
The "SS52 load“ driver program is included in COM PROFIBUS from
V3.1, or it can be requested at no charge via the Siemens Intranet under
