Terminal ID in the terminal network.
Search...
This is used to search all EL6731 channels; the required channel can be selected.
Station no.
Each Profibus device requires a unique station number - including the master.
Baud rate
Set the Profibus baud rate.
Bus parameters (DP)...:
The Bus parameters dialog [} 87] is selected here.
Operation mode
In all three operation modes, the highest-priority task linked to the appropriate device will take control of the
PROFIBUS cycle and is therefore synchronized with the DP cycle (see the Synchronization [} 41] section). If
this task is stopped or reaches a breakpoint, the EL6731 switches to CLEAR mode (slave outputs will
assume 0 or safe values) (see the Error reactions [} 115] section). All other tasks are served asynchronously
via corresponding buffers. If one of these tasks is stopped or reaches a breakpoint, the System Manager will
generally display a message saying that the watchdog of the appropriate asynchronous mapping has been
activated, and the appropriate outputs are set to 0. For all operation modes, one polling rate per slave can be
set (in the Features [} 97] tab for the Box). The sequence of the slaves in the PROFIBUS cycle corresponds
to the sequence in which they are located in the FC310x/EL6731 device tree. "DP" mode is used for
standard DP operation; the operation modes "DP/MC (equidistant)" and "Equidistant (no GC)" are described
in section PROFIBUS-MC [} 40].
Cycle time
Shows the cycle time of the corresponding task with the highest priority.
