Troubleshooting

4 Function

There are basically two modes in which the device can be operated:

• As stand-alone device
The device compares the measured current value with the set parameters and switches its output according to the selected parameters. This mode is without IO-Link functionality. The parameters can only be set with an IO-Link tool.
• As IO-Link device
The device operates as an "analogue/IO-Link converter". The evaluation of the measured current value depends on the parameters which are set with IO-Link tools or a PLC via IO-Link communication.

4.1 Use as a stand-alone device without IO-Link

The device compares the measured current value with the set parameters and switches its output according to the selected function ( → Operation).

The measured value is shown on the alphanumerical display. The displayed value can be scaled by the user (2-point scaling).

8.1 General

Irrespective of the operating mode (standard IO mode or IO-Link device), the device can be configured via an IO-Link tool.

Parameter cloning and parameter setting backup is possible with an IO-Link tool.

The scaling parameter [ScAL] only influences the display and not the transferred process data or the actual switching threshold values.

Via IO-Link, the current value is always transmitted in µA → Representation of the measured current value ( → ☐ 12). The switching thresholds can be set in steps of 0.01 mA.

8.2 Parameters adjustable via IO-Link

The following functions or parameters are only available via IO-Link tools.

8.2.1 SP1/rP1 — set point/reset point OUT1

Upper/lower limit for measuring current at which OUT1 switches with hysteresis setting. Only displayed if the hysteresis function [Hno] or [Hnc] is set in [ou1].

Fig. 5: Hysteresis functions

SP: Switch point

rP: Reset point

HY: Hysteresis

Hno: Hysteresis function normally open

Hnc: Hysteresis function normally closed

▶ Select [SP1] and set the value at which output OUT1 switches.

▶ Select [rP1] and set the value at which output OUT1 switches off.

[rP1] is always smaller than [SP1]. The device only accepts values which are lower than the value for [SP1].

[rP1] follows the changes of [SP1] and keeps the set hysteresis.

8.2.2 FH1/FL1 — min/max switching limits for window function

Upper/lower limit for measuring current at which OUT1 switches within the window setting. The parameters are only displayed if the window function [Fno] or [Fnc] is set in [ou1].

Fig. 6: Window functions

▶ Select [FH1] and set the upper limit.
▶ Select [FL1] and set the lower limit.

[FL1] is always smaller than [FH1]. The device only accepts values which are lower than the value for [FH1].

[FL1] follows the changes of [FH1] and keeps the set hysteresis.

8.2.3 A. Trm – analogue termination for OUT2

• [OFF] = OUT2 is externally connected, e.g. to the analogue input of another device.
- [On] = OUT2 is not connected and the current path is terminated internally.

Note the following for proper current measurement and evaluation: If the internal analogue termination is set to [On], output OUT2 must not be connected.

8.2.4 ou1 — output function for OUT1

Switching signal for the current limits.

• [Hno] = hysteresis function / normally open
• [Hnc] = hysteresis function / normally closed
• [Fno] = window function / normally open
• [Fnc] = window function / normally closed

See also:

SP1/rP1 — set point/reset point OUT1 ( → ☐ 13)

FH1/FL1 — min/max switching limits for window function ( → ☐ 13)

8.2.5 dS1/dr1 — switching delay/switch-off delay for OUT1

Value: 0.0...50.0 s (0.0 = delay time is not active)

8.2.6 ScAL — scaling of the displayed value

The setting defines the position of the decimal point of the displayed value and acts like a multiplier for the parameters [C. ASP]/[C. AEP].

• [OFF] = measured current value is not scaled.
• [cccc] = scaling without decimal place (x 0001).
• [ccc.c] = scaling with 1 decimal place (x 000.1).
• [cc.cc] = scaling with 2 decimal places (x 00.01).
• [c.ccc] = scaling with 3 decimal places (x 0.001).

8.2.7 C. ASP/C. AEP - customer-specific analogue start/end point

Settings for scaled display values.

The parameters are only displayed if [ScAL] is set to [cccc], [ccc.c], [cc.cc] or [c.ccc].

C. ASP value: -746 ... 9745 corresponds to 4 mA.

C. AEP value: -366 ... 9366 corresponds to 20 mA.

If a scaling is set via [ScAL] with parameter setting being done via IO-Link, the C. ASP value and the C. AEP value also have to be selected accordingly:

With [ScAL] = [ccc.c] → C. ASP and C. AEP value x 10

With [ScAL] = [cc.cc] → C. ASP and C. AEP value x 100

With [ScAL] = [c.ccc] → C. ASP and C. AEP value x 1000

With parameter setting being done on the device, the decimal place is displayed. The required values can be selected without having to be converted.

All displayed current values are interpolated based on a 2-point approximation ([SP1]+[rP1], [FH1]+[FL1], [cFH]+[cFL], [Lo]+[Hi]).

IO-Link process data and parameters are not affected by the scaling.

C. ASP = min. value
C. AEP = max. value

C. ASP = max. value
C. AEP = min. value

Fig. 7: Example with scaled display value

	Menu setting	IO-Link parameter setting
ScAL	ccc.c	ccc.c
C. ASP	0.0	0
C. AEP	100.0	1000
Input	10 mA	10 mA
Indication	37.5	37.5

8.2.8 coLr — display colours and colour changes

Assignment of the display colours "red" and "green" within the measuring range.

• [rEd] = continuously red (independent of the measured value).
- [GrEn] = continuously green (independent of the measured value).
• [r1ou] = red when OUT1 switches.
• [G1ou] = green when OUT1 switches.

Fig. 8: Hysteresis function with [r1ou]

Fig. 9: Hysteresis function with [G1ou]

Fig. 10: Window function with [r1ou]

Fig. 11: Window function with [G1ou]

[r-cF] = red when the measured value is between the values [cFL] and [cFH].

[G-cF] = green when the measured value is between the values [cFL] and [cFH].

8.2.9 cFH/cFL — upper/lower value for colour change

When setting [coLr] to [r-cF] or [G-cF]:

▶ Select [cFH] and set the upper limit.
Setting range corresponds to the measured values. The lowest setting value is [cFL].

▶ Select [cFL] and set the lower limit value.

Setting range corresponds to the measured values. The highest setting value is [cFH].

Fig. 12: Function [r-cF]

Fig. 13: Function [G-cF]

For b/w printouts: gn = green, rd = red

8.2.10 diS — refresh rate of the displayed measured value

• [OFF][ = The measured value display is deactivated in the operating mode.]
• [d1] = update of the measured values every 50 ms.
• [d2] = update of the measured values every 200 ms.
• [d3] = update of the measured values every 600 ms.

Even with an unsteady input value, [d1] provides optimum readability.

8.2.11 Lo/Hi — min/max measured input values

[Lo] = lowest measured value

[Hi] = highest measured value

8.2.12 dAP — damping

Damping of the measured analogue value.

Setting also influences the set point, the IO-Link process data and the display.

Value: 0.000...4.000 s (T value: 63 %).

At 0.000 damping is not active.

8.2.13 C.uni – customer-specific unit

Customer-specific unit with max. 4 characters.

8.2.14 Application-specific tag

Customer-specific application description, max. 32 characters long.

Default value: “ *** ” / can be freely defined by the customer

9 Operation

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

9.1 Functions output 1

OUT1 (connector, pin 4):

• Digital output (SIO)
- IO-Link interface

Selectable switching functions:

• Hysteresis functions, normally open / normally closed: SP1/rP1 — set point/reset point OUT1 (→ 13)
• Window functions, normally open / normally closed: FH1/FL1 — min/max switching limits for window function ( → ☐ 13)

OUT1 changes its status if the input signal is above or below the set switching limits. First the switch point SP1 is set, then the reset point rP1: SP1/rP1 — set point/reset point OUT1 ( → ☐ 13).

The hysteresis defined remains even if [SP1] is changed again. Changing the parameter [rP1] also changes the hysteresis.

The width of the window can be set by means of the difference between FH1 and FL1.

FH1 = upper value

FL1 = lower value

9.2 Functions output 2

OUT2 (connector, pin 2):

- Analogue output (looping through the analogue input signal)
