The AADvance Safety Controller Chapter 2
Though the average scan time will be within 1 ms of the scan time calculated
above the calculation does not take into account the effects of application logic
and network communication, and individual scans can vary by up to +/- 4 ms
around the average scan time.
Throughput time is the time from input change to output action. For
asynchronous inputs the throughput times can be derived from the Scan time
calculated above according to the following formulae:
• Minimum throughput time = Scan period + 7 ms
• Maximum throughput time = 2 x Scan time + 13 ms
An example configuration scan time:
System configuration includes T9432 Analogue input simplex modules x 30
and T9451 Digital output simplex modules x 18.
Total I/O modules = 48
Sync time = 32 ms
Scan time = 39.3 ms + 32 ms + (48 x 0.04) ms + (30 x 1.170) ms + (18 x
1.174) ms => 129.5 ms
Minimum throughput time = 129.5 ms + 7 ms => 136.5 ms
Maximum throughput time = (2 x 129.5) ms + 13 ms = 272.0 ms.
Environmental Specification
An AADvance system can be installed in a non-hazardous or a hazardous
environment. In a non-hazardous environment a system does not have to be
installed in an enclosure; however, the area where it is installed must maintain a
Pollution Degree 2 environment (IEC 60664-1).
The following environmental specification defines the minimum
environmental conditions for an AADvance controller installation. Additional
conditions apply to systems installed in a Hazardous environment.
