If the telegram selection (Pr S.01.008) = Auto (0), the number of input and output cyclic
words and the input and output mappings are set by the PLC master on the network.
The mapping configuration parameters can still be changed on the keypad but when the
module or PLC is reset or power-cycled, the PLC will set them up as originally
configured.
If the telegram selection (Pr S.01.008) = Custom (1), the number of input and output
cyclic words and the input and output mappings are set by the user.
If the telegram selection (Pr S.01.008) = STD Tel 1 (2), the number of input and output
cyclic words and the input and output mappings are set by the PROFIdrive parameters.
The mapping configuration parameters can still be changed on the keypad but when the
module is reset or power-cycled, the module will set them according to the selected
telegram (Pr S.01.008).
The input mappings are PNU968 and PNU1001 and the output mappings are PNU967
and PNU1003. Pr S.02.001 will display 5.00.968 (PNU968), Pr S.02.002 will display
5.01.001 (PNU1001), Pr S.03.001 will display 5.00.967 (PNU967) and Pr S.03.002 will
display 5.01.003 (PNU1003).
If the SI-PROFIBUS network diagnostic parameter (Pr S.01.006) indicates "First
Failure" or "Second Failure", a mapping configuration error has been detected. The
reason for the error is indicated by the SI-PROFIBUS input mapping status parameter
(Pr S.01.022) and the SI-PROFIBUS output mapping status parameter (Pr S.01.023).
When a mapping error has been corrected, reset the SI-PROFIBUS module by setting
Pr S.01.002 or MM.007 to On (1).
The input mapping error codes are described in Table 6.7 on page 38 and the output
mapping error codes are described in Table 6.8 on page 38.
