SIPLUS S7-300 FM350-1 -25 … + 60 DGR C ACCORDING EN50155 BASED ON 6ES7350-1AH03-0AE0 . COUNTER MODULE FM 350-1 FOR S7-300, COUNTER FUNCTIONS UP TO 500 KHZ 1 CHANNEL FOR CONNECTION OF 5V AND 24V INCREMENTAL ENCODERS ISOCHRON MODE, MEASUREMENT MODE INCL. CONFIG. PACKAGE ON CD

The FM 350-1 off-loads the CPU by:

  • Direct connection of incremental encoders
  • Direct connection for gate signals (light barrier etc.) using integrated digital inputs.
  • A comparison function and output of response using integrated digital output modules.

The following functions are provided:

  • 1 channel for upcounting and downcounting; 32 bit
  • Counting frequency up to 500 kHz (RS 422 encoders)
  • Counting range 0 to 32 bit or +/- 31 bit, as required
  • One-shot or periodic counting process
  • 1-, 2- or 4-fold evaluation
  • Incremental encoder can be connected
  • Gate control via levels, pulses or software control
  • Setting via the digital input
  • Counter can be loaded with a predefined starting value
  • Comparison function using two selectable comparison values
  • Interrupt response when a comparison value is reached, zero crossing, range violation (selectable)
  • Output signal (24 V-level) that the comparison function controls: With jointly selectable pulse duration or as a continuous signal from the comparison value to the limit of the counting range.

Standard Function Blocks

CNT_CTRL (FC 0)

For controlling the counters of the FM 350-1

DIAG_INF (FC 1)

For providing the diagnostic information of the FM 350-1

Mode of operation

The FM 350-1 counter module detects pulses from incremental encoders at up to 500 kHz, as a function of directly connectable gate signals.

  • It evaluates the direction of the pulses and compares the actual value with two comparison values, which can be preset.There are two possibilities available to output the reaction to the process:
    • 2 digital outputs;
      they can be configured using the selectable minimum pulse or with level switching.
    • Backplane bus;
      the FM 350-1 can send an alarm signal to the CPU via the integrated backplane bus.

Operating Modes

Continuous counting

After the gate is enabled, endless counting takes place between the lower and upper count limit from the starting value

One-shot counting

After the gate is enabled, the system counts once from the starting value to the upper or lower limit depending on the main count direction

  • Main counting direction up: from 0 to the programmable range limit
  • Main counting direction down: from the programmable start value to 0

Periodic counting

After the gate is enabled, periodic counting takes place from the starting value within the programmed counting range depending on the main count direction

  • Main counting direction up: periodic from 0 to the programmed range limit – 1
  • Main counting direction down: periodically from the programmed start value to 1

Parameterization

Parameters are assigned with STEP 7 with the help of parameterization screen forms. A configuring package is available for this purpose.
