1: Conveyor belt

3: DP2122

5: Transistor output / IO-Link

2: Pulse pick-up on the drive shaft

4: Transistor output (e.g. to control a light indicator, horn or relay)

6: Signals depending on the selected switching function

The unit is not suited for environments with particular requirements on mechanical stability (e.g. shock/vibration).

The unit is intended for indoor use only.

▶ Observe the operating conditions ( → Technical data at www.ifm.com).

4 Function

Depending on the setting of the IO-Link parameter [CMPT], the unit displays the current frequency in Hz or the rotational speed in RPM. It generates output signals according to the operating mode and the parameter setting. In addition, it makes the process data available via IO-Link (in Hz or RPM, depending on the operating mode).

The unit is designed for half-duplex communication. So the following options are possible:

• Remote display: reading and displaying the current frequency/speed
• Remote parameter setting: reading and changing the current parameter setting
  • IO-Link parameter setting: IO Device Description (IODD) (→ 8)

4.1 Operating modes

The following operating modes are available:

Operating mode 1: HZ_M (default)
Description	Displays the frequency in Hz
Application	Standard applications with frequency measurement in Hz
IODD designation	DP1222 Factory setting / (CMPT=HZ_M)
IO-Link device ID	1167 d / 00 04 8f h
IO-Link parameter CMPT	HZ_M (default)

Operating mode 2: rpnM
Description	Displays the frequency in revolutions per minute (RPM)

4.3.5 Standard IO mode

The yellow LEDs indicate the switching status of the unit.

Switching function NO:

transistor output	LED yellow	Description
Closed	on	Rotational speed > SP1 and during start-up delay
Open	off	Rotational speed < SP2

Switching function NC:

transistor output	LED yellow	Description
Closed	on	Rotational speed < SP2
Open	off	Rotational speed > SP1 and during start-up delay

4.3.6 Switching delays

The switching delay enables filtering of input signals. The switching delay is activated or restarted by a positive switching edge of the input signal. Only if the input signal is still active after the delay time has elapsed, the output will be set to the active switching state. Pulses that are shorter than the switching delay will be filtered.

4.3.7 Switch-off delay

The switch-off delay enables filtering of input signals. The switch-off delay is activated or restarted by a negative switching edge of the input signal. Only if the input signal is still inactive after the delay time has elapsed, the output will be set to the inactive switching state. Pulse pauses that are shorter than the switch-off delay will be filtered.

4.4 Start-up delay

The start-up delay enables the suppression of error signals when a plant is started. It is effective after the power supply is applied and is dependent on a low speed.

If the drive is frequently switched on and off, it is advisable to couple the voltage supplies of the drive and the speed monitor. By doing so, the start-up delay is active every time the motor is turned on.

If a coupled connection of the voltage supplies is not possible, a start trigger point can be set in the process date or in SIO via ENABLE (Pin 2) via IO-Link. The positive switching edge of the corresponding signal serves as the start trigger point. In addition, the system can start up by itself; after detection of the first pulses the delay timer is started (value: 0...999.9 s in steps of 0.1 seconds).

9.2 Notes on programming

9.2.1 Locking / unlocking

The unit can be locked electronically to prevent unauthorised setting. Set parameter values and settings can be displayed but not changed.

To lock the unit:

▶ Make sure that the unit is in normal operating mode.

▶ Press [esc] + [▲] simultaneously for 10 s.

▷ [Loc] is displayed.

▷ The unit is locked.

▷ [Loc] is briefly displayed if you try to change parameter values.

To unlock the unit:

▶ Press [esc] + [▲] simultaneously for 10 s.

▷ [uLoc] is displayed.

On delivery the unit is not locked.

Customer locking

If [C. Loc] is displayed when an attempt is made to modify a parameter value, an IO-Link communication is active (temporary locking).

Software locking

If [S. Loc] is displayed, the sensor is permanently locked via software. This locking can only be removed using an IO-Link parameter setting software.

9.2.2 Timeout

If no button is pressed for 30 s during parameter setting, the unit returns to the operating mode with the unchanged value.

9.2.3 Numerical entries with [▼] or [▲]

▶ Press [▼] or [▲] for at least 2 s.

▷ After 2 s:

• value is changed continuously by keeping the button pressed.
• value is changed incrementally by pressing the button once.

Value is incrementally reduced with [] and increased with [] .

10 Operation

After power on, the unit is in the operating mode (SIO). It carries out its measurement and evaluation functions and provides output signals according to the set parameters: Menu.
