Parameterization in Frequency Mode

In the frequency mode, the hardware channel 1 or transducer block 1 is used. The hardware
channels 4, 7, 10 are disabled. The hardware channels 2, 3, 5, 6, 8, 9, 11, 12 can be handled
as described in the binary mode section.
4.7.1

Interaction of the Transducer Blocks and AI Function Blocks

The hardware channel 1 frequency input is linked to an AI function block by using channel
number 400. The frequency value is provided by the transducer block 1 via the FREQ
parameter. The XD_SCALE parameter supports "Hz" as unit.

Lead Fault Monitoring

You can independently enable or disable lead short circuit and lead breakage monitoring of the
sensor connections with the Lead Fault Monitoring parameter.
Option
Short Circuit Sensor-A
Lead Breakage Sensor-A
Short Circuit Sensor-B
Lead Breakage Sensor-B
Short Circuit Sensor
Lead Breakage Sensor
The Lead Fault parameter contains the fault status of the sensor connection. Structure and
content is identical to the Lead Fault Monitoring parameter.
