3.4.12 FX3-ANA0 analog input module
Overview
T
he FX3-ANA0 analog input module has two analog inputs for connecting analog signal
transmitters (sensors). The two inputs form an input pair and are used to acquire an
analog process variable. As part of a safety function, the FX3-ANA0 monitors whether
the current value of this process variable (measured value) is within the permissible
process range. In addition, it can assign the measured value to one of up to 15
configurable signal ranges.
The FX3-ANA0 analog input module offers the following functions:
•
Plausibility check of the analog values detected at inputs AI1 and AI2
•
Configurable evaluation of the detected analog values in the module
•
Monitoring of up to 15 different process areas. A process area consists of an
upper and a lower process area limit. If the measured process size of one of these
limits is exceeded or undercut, the Release bit is set to 0. The process area to be
monitored can be selected in ongoing operation.
•
Subdivision of the maximum monitoring range into up to 15 configurable signal
ranges
•
Output of bits for Enable and the number of the current signal range to the main
module for evaluation in the logic editor
•
Output of sensor values via a gateway (16-bit, non-synchronous output, non-safe
transmission)
Important information
NOTE
In some applic
ations, it is necessary to monitor compliance with the ratio of the
recorded sensor values. An explicit ratio formation of different values by the FX3-ANA0
is not possible.
Prerequisites
