3.4 Automatic Activation of Input Channels
All input channels are deactivated by default. Wire break detection is activated (parameter bit
P3 = 1). The measuring range is 4 mA ... 20 mA. The analog module checks the input signals
to detect and automatically activate the connected inputs. This state is indicated by the four
yellow L Ds IN1 ... IN4 illuminating in sequence until at least one connected input is detected.
If no connected input is detected, the peripheral fault is set after 5 seconds. Automatic
activation is still possible.
Activating an Input Channel
An input channel is activated if an input signal within a range of 1 mA ... 23 mA is present. Any
activated inputs remain active after the module is restarted. The sequence and number of
activated inputs can be chosen as required. To use the automatic activation, no jumpers may
be installed between GND and 1CH, 2CH, or 3CH.

Product Description
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, 2CH, or
3CH, and GND, then switch on the supply voltage again.
2. Change the status of parameter 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.
3.6 Manual Activation of the Input Channels
The number of active input channels can be determined using a jumper between the GND and
1CH, 2CH, and 3CH terminals.
Note!
Any change made to the input configuration via a jumper between 1CH, 2CH, or 3CH, and
GND is only detected once the supply voltage is switched on. Changes made via parameter P1
can also be implemented during ongoing operation. See chapter 5.3.
Do not connect the 1CH, 2CH, 3CH, and GND connections to external potentials. The length of
the jumpers must not exceed 5 cm.

5 Commissioning
5.1 Assigning an Address to the Module
To operate the VBA-4 -K 5-IL 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-4 -K 5-IL 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 ... 31. The default address
on delivery is 0.
5.2 Slave Profile
The VBA-4 -K 5-IL has the profile
S-7.3.E
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-4 -K 5-IL. 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: Not sed
Parameter P2: Peripheral Fault
Default value P2=1, active
Parameter P2 is used to switch peripheral fault messages in the event of a measuring
overrange on or off (see chapter 7). If messages are activated, the PWR and FAULT L Ds flash
in the event of a peripheral fault, and a message is sent to the master.
A peripheral fault is always output independently of the parameter P2, if:
■ The power supply is overloaded.
■ There is no external AUX power supply.
■ No channel is activated. See chapter 3.4.

6 Troubleshooting
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 Causes and limination of a Channel Fault
If an input channel is not transferred and the corresponding IN L D does not light up, the
channel is not activated.
If none of these potential solutions correct the fault, 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
■ Disable wire break detection if a measuring range of
0  20 mA is required. See chapter 5.3
No input channel activated ■ Activate input channel (see chapter 3.4)
Auxiliary voltage too low ■ Check the auxiliary voltage
Cause Solution
Bridge is inserted between 1CH,
2CH, or 3CH, and GND
■ Remove the bridge, then reset the power supply
(see chapter 3.6)
Incorrect input channels activated ■ A different input configuration was saved previously
through automatic channel detection. To reset the
input configuration see chapter 3.5

7.2 Delay Times
The module requires a certain amount of time to convert and transmit the analog measuring
signals to the AS-Interface master. This time span (= latency) 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 A
Conversion time
The conversion time is the time that the module requires to convert an analog signal into a
digital value. The conversion time depends heavily on parameter P0
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
50/60 Hz filter inactive (P0=0) 10 ms
50/60 Hz filter active (P0=1) 70 ms
