Transmission time of the analogue values
The transmission time of the analogue values depends on the conver-
sion time of the digital signals into analogue signals in the AS-i mod-
ule and on the transmission time via the AS-Interface.
The conversion time of the digital signals is approx. 1ms.
The transmission time of the 4 16-bit values via the AS-interface ide-
ally is 7 AS-i cycles per value. For a cycle time of 5ms per AS-i cycle this
results in a transmission time of 4 x 7 x 5ms = 140ms via the AS-Inter-
face.
Thus the total transmission time for 4 analogue values ideally is approx.
1ms (conversion time) + 140ms (transmission time) = approx. 141ms.
