4.1.1 Functions

Functions4-][Funktionsbeschreibung BA Einlei tung ST-AI

The module supply provides the module with voltage.

The input signals are read in, analogue prefiltered and converted into
digital signals. The resolution is 12 bits (4095 steps) and is converted
into a 16 Bit value. Additional signal processing can be defined using the
system software (see schematic representation of signal processing).
The individual steps are described in the "Configuration" section.

The input signals are transmitted to the head module via the ST module
bus. As an option the input module can send status information for each
input.

All the configuration data is stored in the head module and is assigned
to the input module on restart. This way the configuration data is re­tained even if you change the input module.

You can configure each channel so that the raw value from the AD con­verter is issued directly, without calibration or scaling.

If the AD converter fails to supply a valid value, the module will adopt the
ADC initialisation value for this channel instead. The default value is

The module has range monitoring and limit value monitoring on each
channel:

 Range monitoring

– Upper limit value: 4095
– Lower limit value: -4095
– The module compares the upper and lower limit value with the dig-

ital value after the hardware calibration (values with 12 bits plus
sign) and writes the result of the comparison as follows:
– System environment A:

In the status byte (see "PSSu assignment in system environment
A")

– System environment B:

In the I/O data element "Overrange" or "Underrange" (see "PSSu
assignment in system environment B").

– The limit of the measuring range corresponds to 4095

 Limit value monitoring

– Limit value 1
– Limit value 2
– The module compares limit value 1 and limit value 2 with the digital

value after scaling (values with 15 bits plus sign) and writes the re­sult of the comparison as follows:
– System environment A:

In the status byte (see "PSSu assignment in system environment
A")

– System environment B:

In the I/O data element "LimitValue1" or "LimitValue2" (see

 Voltages at the input, which are to be monitored through the limit val-

ues:
– Limit value 1 is to be 8 V.
– Limit value 2 is to be 5 V.

 Entry in the system software:

– Limit value 1 corresponds to 26 214
– Limit value 2 corresponds to 16 384

The way in which the analogue value is displayed depends on the volt­age range, on scaling and on the data format. The following examples
show the relationship between the values with default scaling.

The module uses the following data format:

 Two's complement (default)

The digital values are transferred with 15 bits plus a sign bit (MSB).
The MSB is always "0" with positive numbers.

Analogue value and typical digital value with two's complement re­presentation:

5.2 Installing the base module

5.2Installing the base module5200Installing the base module5-][Montage Basismodul

Prerequisite:

 The head module must be installed.

 If the head module does not have an integrated power supply, a sup-

ply voltage module must be installed to the right of the head module.

Please note:

 For mechanical reasons it is not possible to mix base modules with

screw terminals and base modules with cage clamp terminals.

 All contacts should be protected from contamination.

 The mechanics of the base modules are designed for 50 plug in/out

cycles.

Procedure:

 We recommend that you wire up the base modules before inserting

the electronic modules.

 Slot the groove on the base module on to the mounting rail from be-

low [1].

 Push the base module back [2] until you hear it lock into position.

 On the mounting rail, slide the base module to the left until you hear

the two lateral mounting hooks on the adjacent module lock into po­sition [3].

Procedure:

 Pull out the electronic module [2].

Schematic representation:

][Elektronikmodul stecken und ziehen

Please note:

 Only insert on to base modules that are already installed.

 Preferably these base modules should be ready wired.

 Electronic modules with outputs may only be inserted and removed

when the load is switched off. Unforeseeable error reactions may be
triggered if modules are inserted and removed under load.

 When an electronic module is plugged into a base module for the first

time, one part of the coding element remains on the electronic mod­ule, while its counterpart is fixed on to the base module. This is how
the base module is coded.

 The mechanics of the electronic modules are designed for 50 plug in/

out cycles.

The electronic module can be hot swapped. The configuration data is re-

tained when a module is swapped.

Effects:

 System environment A:

– An ST communication error may occur.

 System environment B:

– While the module is disconnected, the substitute values for the

module's signals/values are used (Valid Bits = FALSE).

– Once the module is reconnected, it is reactivated automatically.

][Verdrahtung ST analog

 Safe electrical isolation must be ensured for the voltage supply to the

sensors and actuators. Failure to do so could result in electric shock.

Please note:

 We recommend that you use shielded signal lines.

 On base modules with C-rail:

– Connect the shield to the terminals on the C-rail.
– Connect the C-rail with low impedance to the functional earth.

 On base modules without C-rail:

– Connect the shield as shown in the terminal configuration section.

The module connects the shield to the mounting rail.

– Connect the mounting rail to the functional earth via an earthing

terminal.

 In environments with strong EMC interference, base modules without

a C-rail provide better protection if the shield is connected.

][Verdrahtung Zusatz mit C

 Use copper wiring.

 The terminal configuration as stated on the front plate applies for base

modules with C-rail. The terminal configuration as stated in the tech­nical documentation applies for all other base modules.

6.1.1 Mechanical connection of the base modules

Mechanical connection of the base modules6-][Modulverdrahtung mech

Procedure:

 Use a flat blade screwdriver (DIN 5264-A)!

 Strip the wire back 8 mm.

 If necessary, label the connection level with a colour marker [3].

 Base module with screw terminals:

– Use a screwdriver to loosen the screw on the screw terminal [1]
– Insert the stripped cable into the round fixing hole [2], as far as it

will go.
– Tighten up the screw on the screw terminal.
– Check that the cable is firmly seated.

 On base modules with screw terminals:

– If you use a multi-strand cable to connect the I/Os, it is recom-

mended that you use ferrules conforming to Parts 1 and 2 of DIN

To crimp the ferrules you can use crimp pliers (crimp form A or C)

conforming to EN 60947-1, such as the PZ 1.5 or PZ 6.5 from

Weidmüller, for example.
– Maximum torque setting: 0.8 Nm
