FC 300 Profibus
Influence of the Digital Input Terminals upon FC 300 Control Mode, Par. 8-50 to 8-56
The influence of the digital input terminals upon control of the FC 300 can be programmed in par. 8-50 to
8-56. Please note the par. 8-01 Control Site overrules the settings in par. 8-50 to 8-56, and Terminal
37 Coasting Stop (safe) overrules any parameter.
Each of the digital input signals can be programmed to logic AND, logic OR, or to have no relation to the
corresponding bit in the control word. In this way a specific control command i.e. stop / coast, can be
initiated by fieldbus only, fieldbus AND Digital Input, or Ether Fieldbus OR Digital input terminal.
In order to control the FC 300 via PROFIBUS, par. 8-50 Coasting select must be set to either Bus
[1], or to Logic AND [2], and par. 8-01 Control Site must be set to [0] or [2].
More detailed information and examples of logical relationship options are provided in the Troubleshooting
chapter.
