Operating principle

The SIPLUS FM 350-2 counter module records the pulses from

  • 24 V incremental encoders,
  • direction encoders,
  • initiators and
  • NAMUR sensors

depending on directly connected gate signals.

It compares the counted value with the defined comparison values in both counting directions.

The FM 350-2 provides seven different operating modes for fast and simple adaptation to the desired application. With the exception of the “dosing” operating mode, all channels can be used independently in any operating mode:

Operating modes

Continuous counting

After the gate has been enabled, counting is performed continuously (beginning with the starting value) between the upper and lower limits.

Single count

After the gate has been enabled, counting is performed once (beginning at the starting value) to the upper or lower limit depending on the main count direction.

  • Main count direction upwards: from 0 up to the parameterizable full-scale value
  • Main count direction downwards: from the parameterizable start-of-scale value down to 0

Periodic count

After the gate has been enabled, counting is performed periodically (beginning at the starting value) within the parameterized counting range depending on the main count direction.

  • Main count direction upwards: periodically from 0 up to the parameterizable full-scale value 1
  • Main count direction downwards: periodically from the parameterizable start-of-scale value down to 1

Frequency counting

After the gate has been enabled, all the pulses received within a parameterizable time frame are counted and the frequency is determined from this.

Speed measurement

After the gate has been enabled, all the pulses received within a parameterizable time frame are counted and the speed is determined from this.

Period measurement

After the gate has been enabled, all the pulses received within a parameterizable time frame are counted and the period is determined from this.

Dosing

4 counter channels are combined to form one proportioning channel. After the gate has been enabled, proportioning is performed once (beginning at the starting value) to the upper or lower limit depending on the main count direction.

  • Main count direction upwards: from 0 up to the parameterizable full-scale value
  • Main count direction downwards: from the parameterizable start-of-scale value down to 0

Two possibilities are available for output of the response to the process:

  • Digital outputs:
    a digital output is directly assigned to each counter channel to allow a fast response.
  • Backplane bus:
    the FM 350-2 can send process interrupts to the CPU via the integral backplane bus.

The following alternatives are available on failure of the CPU:

Failure responses

Description

Cancellation

The outputs are switched off immediately, the counting/measuring processes are canceled.

Continue

The module continues counting/measuring unchanged, even after a restart of the CPU

Switch to substitute value

Active counting/measuring processes are cancelled. The module applies the configured substitute values at the outputs, channel by channel.

Keep last value

Active counting/measuring processes are cancelled. The module’s outputs are frozen in the state they had immediately before canceling.

Parameter settings

Parameterization is performed with STEP 7 with use of the parameterization screen forms. A configuration package is available for this:

Commissioning

4-page brief instructions are enclosed with the configuration package to allow fast and simple startup of the module, and lead to a functioning application in max. 1 hour by using a specific example. When doing this, the following steps must be taken into account:

  • Requirements
  • Installing the configuration package on the programming device
  • Installation and wiring of the FM 350-2
  • Generation of counter DBs
  • Parameterization of FM 350-2
  • Integration into the user program
  • Diagnostics

A further example serves for orientation and adaptation to the desired application.
