FX2N-32DP-IF Profibus-DP Interface Unit
Appendix C:
C-18
C-2-6:
FX
2N
-4DA Extension Configuration (Motorola Format)
Requirements:
•
Cyclic data is 4 word outputs in every cycle.
•
Parameter is 50 bytes.
•
For the FX
2N
-4DA the GSD-File is using a setting which is different to the default of the
FX
2N
-4DA. The BFM #5 is set to 1111hex which will reset the analog outputs to the offset
value if there is no further FROM/TO instruction.
The reason for this setting is the behavior of the FX
2N
-32DP-IF, according to the Profibus
specification it will set the cyclic output data to '0' if the Slave detects an internal
watchdog error (Profibus down). In the case of the FX
2N
-4DA ext. & short configuration,
an internal watchdog error will set the analog output data of channel 1,2,3 and 4 to 0
which means offset value.
•
To hold the last output value, please use 'simple communication', because this
communication style is accessing the BFMs indirectly. In the case of a watchdog error of
the FX
2N
-32DP-IF, access to the FX
2N
-4DA will be stopped but the last output data will be
held if BFM #5 is set to 0 for the corresponding channel.
