The T400 offers various ways to process and transfer synchronizing signals.
The processing possibilities are listed in the following diagram. The three
selector switches indicated, are set by appropriate configuring.

The basic cycle of the T400 can be taken from three various sources (can
be configured in HWConfig):
• Basic cycle time of the T400 (standard)
• Synchronizing signal of the BASE BOARDs (L_INT_CU_DPR (connector
X1/B25) for T0GATE)
• Synchronizing signal of the COM BOARDs (L_INT_DPR_PT (connector
X2/A26) for T0GATE)
Thus, a cycle from the CBX can synchronize the T400 and BASE BOARD
(CU).
Configurable interrupt tasks can also be called using the synchronizing
signals from BASE- or COM BOARDs (ports A/4, A/5).
The T400 can supply BASE- and COM BOARD synchronizing signals, which
come from the following three sources and can be selected by appropriately
configuring:
• Basic cycle time of the T400 (T0OUT of MFB1)
• Directly connecting synchronizing signals from the BASE- or COM
BOARD to the other module
• In an FP with a special FB-generated synchronizing signal
(SYNC_BASE, SYNC_COM)
