Note:
The internal structure of mapping-parameters (PD_Inx_Map, PD_Outx_Map) does not support the attribute ‚Bi-
tOffs’. Therefore the BitOffs is related to the order of the mappings.
I.e.:
BitOffs(1) = 0
BitOffs(2) = BitLen(1)
BitOffs(3) = BitOffs(2) + BitLen(2)
BitOffs(4) = BitOffs(3) + BitLen(3)
ATTENTION !!! The process data of the structure 1*32-Bit + 1-2 times 16-Bit for output data and input data must
follow for the synchronous mode.
Finally, after changing the mappings, the number of the mapped objects (Subindex=0) must be written via mail-
box-command-layer (SDO) in the respective mapping object (1600h or 1A00h, s [2]) in order that the process
data processing becomes active.
3.2.2 Synchronous mode
The Powerlink SoC-Interrupt is used as synchronization signal for internal communication between Powerlink
operator and FI control in this special kind of communication. The synchronous mode causes a process data as-
signment according to the rules specified above. The receipt of an SoC interrupt is referred as SYNC event in the
following documentation. The operator display is fixed to ‚Synch‘ in the synchronous mode.
This special communication mode causes some restrictions in the functionality of the Powerlink operator. To the
mentioned display also the keyboard is inactive.
The diagnostic interface remains in operation. The adjusted synchronous cycle time can be read off via diagnostic
interface at operator parameter
FB.00: ComCycle
.
The PDOUT data are transferred to the FU control and the current PDIN data to Powerlink are updated during
each synchronous cycle.
