The delay time is set by means of the UserPrmData (in µs, in Motorola format). The extended
GSE file of the Bus Coupler is, however, necessary for this:

Delay time (in µs) high byte

Delay time (in µs) low byte
Synchronous Mode With Optimized Input Update (two cycles)
In the third mode of synchronous operation, the advantages of the other two operating modes
are combined. Two Standard-Bus cycles are carried out within one DP cycle. The first cycle
begins immediately after reception of the Data_Exchange telegram from the master, which
means that the outputs are generated as quickly as possible. The second cycle is started
after a delay time that begins after completion of the first cycle has elapsed, so that the inputs
are as recent as possible. It is important here to ensure that twice the duration of the
Standard-Bus cycle, plus the delay time, plus approx. 20% (to allow for the lower priority
processes on the coupler) is shorter than the DP cycle time.
