Parameterization in Counter Mode

In the counter mode, the hardware channel 1 or transducer block 1 is used. The hardware
channels 4, 7, and 10 are disabled. The counter value can be either linked to an AI function
block as a float value or to a DI function block as an unsigned 8 value. The hardware
channels 2, 3, 5, 6, 8, 9, 11, and 12 can be handled as described in the sensor mode section.
One DO function block serves for resetting the counter value to 0.
4.8.1

Interaction of the Transducer Blocks and AI, DO Function Blocks

The hardware channel 1 counter input is linked to an AI function block by using channel
number 400. To reset the counter value, a DO is available which is linked to the transducer
block by using channel number 500. The hardware channels 2, 3, 5, 6, 8, 9, 11, and 12 can be
handled as described in the sensor mode section.
The counter value is provided by the transducer block 1 via the CNTR_VALUE_D parameter.
The FINAL_VALUE_D transducer block parameter contains the actual counter reset state.
4.8.2

Interaction of the Transducer Blocks and DI, DO Function Blocks

The counter value can be mapped as an unsigned 8 bit value to a DI function block using
channel number 401. If the counter value exceeds 255, the HI_LIMIT status is set. To reset the
counter value, a DO is available which is linked to the transducer block by using channel
number 500. The hardware channels 2, 3, 5, 6, 8, 9, 11, and 12 can be handled as described
in the sensor mode section.
4.8.3

Lead Fault Monitoring

In counter mode, no lead short circuit monitoring is supported.
