Much greater flexibility is afforded by the interconnection of process data using
binectors/connectors, see description "Use of binectors and connectors" in the
reference manual.
Detailed connection of setpoints and actual values to and from the PROFIBUS
optional board is parameterized in "r2050" and "P2051".
The following table shows the parameters specific to the PROFIBUS optional board
relating to the connection of process data:

r2050 also acts as a display parameter via which the setpoints received by the
PROFIBUS optional board can be checked.

A number of advanced property settings for the PROFIBUS optional board can be
made in indexed parameter "P2041".
For most applications, however, the defaults are adequate (value = 0). The
following table shows the property setting options.

P2041.00
PPO type is specified by slave:
Some (rare!) PROFIBUS masters require
a configuration specified by the slave.
This option can be programmed in this
parameter.
0: PPO1
1: PPO1
3: PPO3
P2041.01 OP parameter in EEPROM:
Modifications to parameter settings via
SIMATIC HMI are stored permanently in
the EEPROM or as volatile data in the
RAM.
0: Permanent (EEPROM)
1: Volatile (RAM)
P2041.02
Internode communication failure:
Reaction of communication board (as
subscriber) after failure of a publisher
0: Generate alarm A704 and abort
setpoint transmission to converter
(may activate fault 70)
1: Generate alarm A704 only
P2041.03 Select displayed diagnostics screen. 0: Standard diagnostics
>0: Special diagnostics (for SIEMENS
internal use only)
