AEZ 414
Timing of measurements
General
Measurement sequence
The cycle time of the TSX AEZ 414 module and consequently the sampling period are independent from the power frequency (50 Hz or 60 Hz).
Internal module temperature (cold junction) acquisition is added to the full acquisition of the four channels
The measurements are sequenced in the following manner:
Tcycle = 520 ms
Tchannel
Value of available channel n
New value of available channel n
Scanning time
Internal temp.
Channel
0
Channel
1
Channel
2
Channel
3
Internal temp.

The scanning cycle is always identical even if some channels or the internal temperature are not used. It is equal to 520 ms.
The table below shows the module scanning times:

Note: Module initialization can take up to 1.5 s. During this time the channels are signaled "not ready" by bit 8 of the channel status word: %MWx.i.2:X8
