User modification and or repair are dangerous and will void the warranty and exclude the
manufacturer from any liability. If serious faults occur, stop using the device. Secure the device
against inadvertent operation. In the event of repairs, return the device to your local
Pepperl+Fuchs representative or sales office.
The connection of the device and maintenance work when live may only be carried out by a
qualified electrical specialist.
The operating company bears responsibility for observing locally applicable safety regulations.
Store the not used device in the original packaging. This offers the device optimal protection
against impact and moisture.

Product Description
4.2 Connections
Figure 4.2 Connections
The VBA-4E-G11-I-F analog module is equipped with the following connections:
Current inputs
: functional ground
M12 round plug connector
Addressing socket Low voltage switch socket, 1.3 mm
4.3 Activating the Input Channels
All input channels on the analog module are deactivated by default. This state is indicated by
the four yellow LEDs IN1 to IN4 illuminating in sequence. Wire break detection is activated
(parameter bit P3=1). The measuring range is between 4 mA and 20 mA.
Activating an Input Channel
An input channel is activated if an input signal within a range of 1 mA to 23 mA is present. Any
input channels activated remain active after the module is restarted.
Resetting Activated Input Channels
In order to restore the module to its default status, set parameter bit P3 to P3=0 and then to
P3=1. Alternatively, when switching on the module, a signal of < 1 mA must be present at all
input channels for a period of 7 seconds.
Note!
Where wire break detection is deactivated (parameter bit P3=0), all four input channels are
activated. The measuring range is between 0 mA and 20 mA.

5.1 Storage and transport
For storage and transport purposes, package the unit using shockproof packaging material
and protect it against moisture. The best method of protection is to package the unit using the
original packaging. Furthermore, ensure that the ambient conditions are within allowable range.
5.2 Unpacking
Check the product for damage while unpacking. In the event of damage to the product, inform
the post office or parcel service and notify the supplier.
Retain the original packaging in case the device must be stored or shipped again at a later
date.
Should you have any questions, please direct them to Pepperl+Fuchs.
5.3 Mounting
Align the device as required and secure to a flat mounting surface by screwing it in place with
two M4 mounting screws. When the central screw is tightened, the functional ground of the

Commissioning
6 Commissioning
6.1 Assigning an Address to the Module
To operate the VBA-4E-G11-I-F within an AS-Interface network, a suitable address must be
assigned to the AS-Interface slave. The AS-Interface VBP-HH1-V3.0 handheld device by
Pepperl+Fuchs or an AS-Interface master can be used to assign addresses.
The VBA-4E-G11-I-F 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.
6.2 Slave Profile
The VBA-4E-G11-I-F has the profile
S-7.3.E
I/O = 7
ID = 3
ID1 = F (programmable)
ID2 = E
The data value is transmitted as defined by AS-Interface profile 7.3.
6.3 Parameterization
The fol lowing parameters c an b e se t for the VBA-4E-G1 1-I-F. P rogram 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 paramete r P0 , yo u activate the filter for 50/6 0 Hz power frequencies. W ith an ac tivated
filter, power frequ ency interference is suppressed. In this case, the conversion time is extended
(see chapter 9.2).
Parameter P1: Not Used
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
ove rrange on or off (se e chapter 9). If notifications are ac tivate d, the AS-i/FAULT LED fl ashes in
the event of a peripheral fault, and a notification is sent to the master.
A peripheral fault is always reported if:
■
The power supply is overloaded.
12
■
The external power supply is not available when the INT/EXT switch = EXT.
■
No channel is activated. see chapter 4.3.
Parameter P3: Wire Break Detection
Default value P3=1, active
Parameter P3 is used to switch wire break detection on or off at the input channels. Where wire
break detection is activated, automatic channel detection is also activated (see chapter 4.3).
The measuring range is between 4 mA and 20 mA.
Parameter P3=0 is used to switch off wire break detection. All four input channels are then
active. The measuring range is between 0 mA and 20 mA.

Troubleshooting
7 Troubleshooting
7.1 Causes and Elimination of Peripheral Faults
A peripheral fault (P fault) is indicated by the color and flashing of the AS-i/FAULT LED. There
are various causes of and solutions for correcting peripheral faults.
Cause Solution
Sensor supply overload
Measured values outside the measuring range
Auxiliary power too low (switch set to EXT)
No input channel activated Activate input channel (see chapter 4.3)
If none of these potential solutions correct the peripheral fault, please contact Pepperl+Fuchs.

9.2 Delay Times
The VBA-4E-G11-I-F needs a certain amount of time to convert and transmit the analog
measuring signals to the AS-Interface master. This time period (= latency) is mainly composed
of the conversion time and the transmission time. The conversion time and the transfer time
depend on several 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

VBA-4E-G11-I-F
Appendix B
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
50/60 Hz filter inactive (P0=0) 10 ms
50/60 Hz filter active (P0=1) 70 ms
Tab le 9 . 3
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 = 150s * ([Number of occupied addresses] +2)
The transmiss io n time is 7 cyc le s:
Transmission time = 150s * ([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 = 150s * (3 +2) * 7 = 5,25 ms
■
4 occupied addresses : Transmission time = 6,3 m s
■
31 occupied addresses: Transmission time = 35 ms
