Operating Mode; Measuring Process In Single-Channel Mode; Measuring Process In 2-Channel Mode - WAGO 750-645 Manual

4.1.1.6.1 Operating Mode

The following operating modes can be set for each channel:
·
·
·
·
Please note
If the I/O module is to be used in machine protection, only one channel may
be operated in Vibration monitoring mode, the other channel must be turned
off (no measurement).
When using the module in condition monitoring, both channels may be used
in any combination of operating modes.

4.1.1.6.1.1 Measuring Process in Single-Channel Mode

In 1-channel mode, measurements are performed continuously after a
once-only settling time (tS) of 10 seconds
threshold
(Power up)

4.1.1.6.1.2 Measuring Process in 2-Channel Mode

IIn 2-channel mode, using two sensors in both active channels (configurable
using WAGO-I/O-CHECK), the sensor measurement data of these two
channels is processed sequentially.
a) After channel switchover internally, the settling time (tS) of 10 seconds
runs only in one channel. During this time, the measurement signal must
settle due to filters. The control system process data for neither channel is
updated (frozen) during this period.
