MC tab

Task-Access-Time (Shift-Time): This time must be greater than the maximum TwinCAT jitter plus the maximum mapping time (see chapter PROFIBUS MC)

Task access time/task cycle time: This ratio makes sense if you want to avoid manually adjusting the task access time when using the Calculate MC-Times button.

PLL-Sync-Time: Only relevant for Sync-Mode Disabled, sets the PLL window on the FC310x

Task Cycle Time: Displays the cycle time of the corresponding highest priority task

Estimated DP-Cycle Time: Displays the expected PROFIBUS cycle time. 

Estimated Mapping Time: Indicates the expected mapping time. 

Set To on Box: The To-time can be set individually for each slave on the Prm data (text) tab of the box

Set Ti on Box: The Ti-time can be set individually for each slave on the Prm data (text) tab of the box

To-Time: If the checkbox Set To on Box is not ticked, the To-time can be set to the same value for all slaves.

Ti-Time: If the checkbox Set Ti on Box is not ticked, the Ti-time can be set to the same value for all slaves

Estimated Equi-Cycle Time: Shows the DPV2 part of the expected PROFIBUS cycle time. 

Calculate MC-Times: This button can be used to calculate all DPV2 times automatically

Sync-Mode: The Sync-Mode decides whether the FC follows the PC (disabled) or whether the PC follows the FC (master), in order to synchronize the TwinCAT cycle with the PROFIBUS cycle
