The corresponding device range used in the CPU memory is

calculated automatically.

Automatic Refresh

The automatic refresh function sets the automatic refresh parameters for the PROFIBUS slave

QJ71PB93D in the parameter file stored in the System Q CPU. This file manages parameter data

for all special function modules of the System Q.

Via automatic refresh the input and output areas of the PROFIBUS slave are transferred to or

from a user definable device area in the CPU. This method provides direct and fast access

without using FROM/TO instructions.

For details refer to the hardware manual of the QJ71PB93D slave module.

Consistency

The consistency function can be activated for System Q CPUs from OS version B (Sep. 2000).

The consistency function interlocks simultaneous access to the buffer memory by the CPU and

the DP slave. This way, data consistency especially required for high-speed applications is

automatically ensured.

This interlock mechanism slightly decreases the transfer speed. Therefore, only enable the

consistency function, if you require data consistency.

For details refer to the hardware manual of the QJ71PB93D slave module.

Note:

Only the FDL address, the autorefresh flag, and the consistency flag are transferred to

the DP slave. The size settings in the slave parameter settings dialog are relevant only

for the data exchange between DP slave and System Q CPU via autorefresh.
