3.4 Automatic Detection of the Sensor Type
ach of the two input channels can be operated either as a current or a voltage input. The
analog input module automatically detects the type of sensor connected. 0 V  10 V or 0/4 
20 mA measurement sensors can be connected as sensor types. The automatic detection
process occurs after the device is switched on. The detected sensor type is saved in the non-
volatile memory and reactivated when the device is switched on again.
The valid signal values that ensure unambiguous detection of the type of sensor connected
are:
■ Voltage: 1 ... 11.5 V
■ Current: 1 ... 23 mA
If the module cannot clearly establish which sensor type is connected, the last detected sensor
type is provisionally activated. For example, the module may not detect which sensor type is
connected if the signal values are not within the specified thresholds or if two different sensor
types are simultaneously applied to one channel.
A specific sensor type is finally activated when the signal values measured are within the
specified thresholds.
3.5 Resetting the Automatically Detected Sensor Types
Any sensor types saved through automatic detection are reset when the input configuration of
the module is manually changed. For this, there are two available options:
1. Switch off the module power supply. Place or remove the jumper between 1CH and GND,
then switch on the supply voltage again.
2. Change the status of parameter P1 or P3 (see chapter 5.3). In this case, it is not necessary
to switch the supply voltage off and on.
Repeat this process if necessary to return to the required input configuration.
Note!
Switching Off the Second Channel
Figure 3.3 Jumper for switching off input channel 2
Input channel 2 can be deactivated using a jumper between the GND and 1CH connections or
using parameter P1. The jumper has priority. If no jumper is set and P1 = 1, then both channels
are active.

Note!
Any change made to the input configuration via a jumper between 1CH and GND is only
detected once the supply voltage is switched on. Changes made via parameter P1 and P3 can
also be implemented during ongoing operation. See chapter 5.3.
Do not connect the 1CH and GND connections to external potentials. The length of the
jumpers must not exceed 5 cm.
Note!
If you connect two different sensor types to one channel simultaneously, fault-free operation is
not guaranteed. The module will not be damaged by this.

5.1 Assigning an Address to the Module
To operate the VBA-2 -K 5-IJL/UJL within an AS-Interface network, a suitable address must
be assigned to the AS-Interface slave. The AS-Interface VBP-HH1-V3.0 handheld
programming device by Pepperl+Fuchs, for example, or an AS-Interface master can be used to
assign addresses.
The VBA-2 -K 5-IJL/UJL is a standard slave as defined by specification 3.0 and requires a
master that meets specification 2.1 or higher. You can assign addresses 1 to 31. The default
address on delivery is 0.
5.2 Slave Profile
The VBA-2 -K 5-IJL/UJL has the profile
S-7.3.D
The data value is transmitted as defined by AS-Interface profile 7.3.
5.3 Parameterization
The following parameters can be set for the VBA-2 -K 5-IJL/UJL. Program the parameters
using an AS-Interface master, with the VAZ-SW-ACT32 AS-i Control Tools from
Pepperl+Fuchs, or with the VBP-HH1-V3.0 handheld device.
Parameter P0: 50/60 Hz Filter
Default value P0=1, active
With parameter P0, you activate the filter for 50/60 Hz line frequencies. With an activated filter,
line frequency interference is suppressed. In this case, the conversion time is extended (see
chapter 7.2).
Parameter P1: Second Channel
Default value P1=1, active
Parameter P1 is used to switch the second measurement channel on or off. If the second
channel is switched off, this can considerably reduce the conversion time in the module. (see
chapter 7.2)
Alternatively, you can control the second channel via a jumper between terminals 1CH and
GND. (see chapter 3.3)
I/O = 7
ID = 3
ID1 = F (programmable)
ID2 = D
Note!
The jumper between terminals 1CH and GND overrides parameter P1.

Parameter P2: Peripheral Fault
Default value P2=1, active
Parameter P2 is used to switch notification of a peripheral fault in the event of a measuring
overrange on or off (see chapter 7). If messages are activated, the PWR L D and FAULT L D
flash in the event of a peripheral fault, and a message is sent to the master.
A peripheral fault is always output independently of parameter P2, if:
■ The power supply is overloaded.
■ The external power supply is not available when the INT/AUX switch = AUX.
Parameter P3: Current input 0 ... 20 mA
Default value P3=1, not active
Parameter P3=0 is used to set both input channels to current mode. Wire break detection is
simultaneously deactivated. (see chapter 7.1)

6.1 Causes and limination of a Peripheral Fault
A peripheral fault (P fault) is indicated by the PWR L D and the FAULT L D flashing alternately.
There are various causes of and solutions for correcting peripheral faults.
6.2 Cause and limination of a Channel Fault
If channel 2 is not transferred and L D IN2 is not illuminated, channel 2 is not activated.
6.3 Cause and limination of a Sensor Fault
If connected sensors are not recognized or no meaningful data is delivered, this could have
been caused by the issues below.
If none of these potential solutions correct the fault, please contact Pepperl+Fuchs.
Cause Solution
Sensor supply overload ■ Check sensor supply for short circuit
Data outside the measuring range ■ Check connected sensors for wire break/short
circuit
Wrong sensor type configured ■ A different sensor type has already been configured
through automatic detection of sensor type. To reset
the sensor configuration, see see chapter 3.5
Auxiliary voltage too low (switch set
to AUX)
■ Check the auxiliary voltage
Cause Solution
Jumper is inserted between 1CH
and GND
■ Remove the jumper, then reset the power supply
(see chapter 3.3)
Parameter P1=0 ■ Change parameter P1 (see chapter 5.3)
Cause Solution
Voltage sensor connected to current
input (II1, II2)
■ Check the connection of the sensors. See chapter
3.3 and see chapter 4.5
Current sensor connected to voltage
input (IU1, IU2)
Both sensors connected to the same
input channel (IU1 and II1 or IU2 and
II2)
Wrong sensor type configured ■ A different sensor type has already been configured
through automatic detection of sensor type. To reset

7.2 Delay Times
The analog input module requires a certain amount of time to convert and transmit the analog
measuring signals to the AS-Interface master. This time span is mainly composed of the
conversion time and the transmission time. The conversion time and transmission time depend
on a number of factors.
Latency
Latency = delay of a signal under worst case conditions.
The analog-to-digital conversion in the analog module and the transmission via AS-Interface is
not in sync. In the worst case, the transmission of a channel via AS-Interface starts just before
the conversion of this channel is completed within the module. This gives rise to two scenarios:
1. The conversion time is longer than the transmission time
Latency = Conversion time + Transmission time * (Number of channels +1)
2. The conversion time is shorter than the transmission time
Latency = Conversion time * (Number of channels +1) + Transmission time

Appendix
Transmission time
The transmission time is based on the AS-Interface specification. The AS-Interface transmits
data in 4-bit packets. At values greater than 4 bits, the quantity of data is divided into smaller
values and then transmitted to a com unit over several cycles. If several channels are
transmitted per slave, the number of cycles increases. The transmission time is the time
required to fully transmit a digital data volume to the com unit. In the profile 7.3, seven frames
are required per channel.
The duration of a cycle depends on the number of occupied addresses in the AS-interface
network. An address is considered occupied if one of the following configurations apply:
■ A standard address is assigned (e. g. 1)
■ An A- or B-Address is assigned (e. g. 1A or 1B)
■ An A- and a B-Address are assigned (e. g. 1A and 1B)
When calculating the cycle time, each of these configurations assumed to be one occupied
address.
Cycle time = 150µs * ([Number of occupied addresses] +2)
The transmission time is 7 cycles:
Transmission time = 150µs * ([Number of occupied addresses] +2) * 7
Example:
In a network, the addresses of 1A, 1B, 2A and 3 are assigned. For the calculation of the
transmission time this corresponds to 3 occupied addresses. Thus we have:
Transmission time = 150µs * (3 +2) * 7 = 5,25 ms
■ 4 occupied addresses: Transmission time = 6,3 ms
■ 31 occupied addresses: Transmission time = 35 ms
