AS-i/PROFIBUS Gateway
General Information
4 General Information
This operating instruction is for use with the following devices of the Pepperl+Fuchs
GmbH:
• VAG-PB-KF-R4
The AS-i/PROFIBUS-Gateways serve to connect the Actuator-Sensor-Interface to
the PROFIBUS-DP. A gateway represents the master for the AS-Interface and the
slave for the PROFIBUS.
The AS-i/PROFIBUS-Gateway is constructed as a PROFIBUS DP slave only. It supports all PROFIBUS transmission rates up to 12 MBaud.
All AS-Interface functions can be called via the Profibus. There are three operation
modes for the data exchange with Profibus-DP: the easy mode, the advanced mode
and the professional mode. In the easy mode, the gateway uses a fixed I/O-configuration for the Profibus and the gateway can be put into operation very easily without
further parameterization on the Profibus master. In the advanced mode, the size of
the I/O window can be matched to the actual structure of the AS-i network. The AS-i
master is configured by the Profibus master. During operation, AS-i parameters can
be transmitted to the AS-i slaves. Also the mini-PLC AS-i Control is accessible. All
AS-i Control functions are available (program download, upload, start, stop, read and
write user memory). The professional mode is the advancement of the advanced
mode. With its management channel it is additionally possible to execute further AS-i
commands via Profibus. Furthermore you can operate the advanced AS-i diagnosis
via Profibus.
The scope of delivery includes several GSD-files to ensure the easy putting into operation in each operating mode. In contains also the Siemens type files version 4.0
(German) and 5.x.
All devices contain the integrated mini-PLC AS-i Control for the fast distributed preprocessing of AS-i data. Furthermore advanced AS-i diagnosis functions are implemented to locate sporadically occurring configuration errors and to judge the quality
of the AS-i communication.
All devices are delivered together with the AS-i Control Tools, a Windows software for
the easy putting into operation of the AS-Interface and the programming of AS-i Control. The software communicates via the serial interface of the PC without additional
expensive hardware. Merely a Profibus converter is needed to connect the RS232 interface of the PC with the Profibus interface of the AS-i/PROFIBUS Gateway.
If no PC is available the putting into operation, troubleshooting and setting up of the
AS-i parameters can be accomplished with the use of two push-buttons, the display
and the LEDs directly on the device.

The seven LEDs on the front of the gateway signal the following:
power The gateway is sufficiently supplied with power.
PB active LED on: The PROFIBUS communications are active.
LED off:PROFIBUS communications are inactive.
config err A configuration error is imminent or no PROFIBUS communications
are taking place (when the "PB active" LED is not illuminated). This
means that with configuration errors, at least one projected slave is
missing or the actual configuration data does not correspond with the
reference configuration data for a projected and recognized slave.

AS-i active Standard operation is active (AS-i Flag "Normalbetrieb").
prg enable Automatic address programming is possible
(AS-i Flag "Auto_prog_available").
Precisely one slave is missing in the protected operating mode. This
slave can be replaced with a slave of similar design and an address
of 0. The gateway automatically programs the new slave to the faulty
address and thereby resolves the configuration error.
prj mode The gateway is in the projection mode
(AS-i Flag "projecting_active").

5.3 Mounting and Connections
5.3.1 Mounting
The KF… design of the gateway can be mounted on a 35 mm DIN rail in accordance
with EN 50022 and facilitates electrical connection through the "Power Rail". It is also
possible to use the more conventional and expensive method of cable connections to
terminals with this design.
The gateway is snapped directly onto the DIN rail. When using the power rail, an electrical connection is automatically made (to the AS-i Bus) by snapping the gateway
onto the rail leads..
5.3.2 Connection via the Power Rail
The PR05 power rail is an insert for the DIN rail in accordance with EN 50 022. The
UPR 05 is delivered with the appropriate DIN rail.
The 5 pin version of the power rail must be used during the establishment of AS-interface circuits. Two of the five power rails make up the AS-i bus.

5.3.3 Device Terminal Connections
In addition to or in combination with power rail connections, the KF… designs can be
conventionally connected by means of removable device terminals. The terminal arrangement is shown below.
The device terminals consist of screw type cable piercing terminals which allow for
the connection of 14 AWG cables (2.5 mm²). The connectors are 3 pin connectors;
they can be keyed to prevent connection errors.
Removable terminals simplify the assembly of the switch encloser and allow for the
replacement of components without taking the system off line.
5.3.4 Gateway Power Supply
The gateway is supplied through the AS-i circuit. A connection to the AS-i cable is established by means of the power rail and/or with the device terminals. The terminal
layout is displayed in the diagram above.
It is important to note when using the power unit that these AS-Interfaces are compatible and have the necessary decoupling coils.
5.4 The PROFIBUS Interface
The serial interface is a 9 pin SUB-D connector. It is located on the right side of the
device front. The other possibility is to use the device terminals. The wiring is shown
in the picture below:

Operating the AS-i/PROFIBUS Gateway
6 Operating the AS-i/PROFIBUS Gateway
6.1 Master Start-Up
After powering on, all segments of the figure display and all LEDs light up for approximately one second (self-test). Afterwards, the LEDs display the condition of their respective flags. The LCD displays the condition of the master:
40 Off-line Phase
The AS-i Master initializes—there is no data communication on the AS-i.
If the AS-i circuit is insufficiently powered (“U ASI” does
not light up) or there is no communication relationship
between the Profibus master and the AS-i/PROFIBUS
Gateway, the master remains in the off-line phase.
In configuration mode or when an AS-i Control program is started automatically the device can leave the Off-line phase.
In protected mode, if the Profibus communication is interrupted, the AS-i
Master switches to the off-line phase after the watchdog time of the Profibus has expired unless an AS-i Control program is running and was
started automatically.
41 Detection Phase
Start of the start-up phase, where the system looks for slaves located on
the AS-i. The master remains in the detection phase until it finds at least
one slave.
42 Activation Phase
Condition at the end of the start-up operation where the parameters are
transmitted to all connected and recognized slaves. This enables access
to the AS-i slaves’ data connections.
431Start of Normal Operation
In normal operation the AS-i master can exchange data with all active
slaves. It transmits management messages and looks for and activates
newly connected slaves. During normal operation, the system keeps the
maximum cycle time of 5 milliseconds.
6.2 Configuration Mode
The configuration mode serves to configure the AS-i circuit.
In the configuration mode, all recognized slaves are activated even
when the desired and actual configurations do not match.
1. Activation phase and the start of normal operation maybe so short that the numbers can not be seen in the display.

AS-Interface
Operating the AS-i/PROFIBUS Gateway
Pressing the “mode” button for at least five seconds switches the master to configuration mode. While in configuration mode, the yellow “prj mode” LED lights up.
The system then displays one after the other all detected slaves at a speed of two per
second. If the display is empty, no slaves were detached on the AS-i circuit.
In configuration mode, all recognized slaves are activated except of slave zero. The
AS-i Master is in normal operation. There is data exchange between the AS-i Master
and all AS-i slaves detected by the master regardless of whether the detected AS-i
slaves were projected before.
When delivered the AS-i/PROFIBUS Gateway is in configuration mode.
6.3 Protected Operating Mode
In contrast with the configuration mode in the protected mode there is
only data exchange between the AS-i Master and the projected AS-i
slaves.
6.3.1 Switching to Protected Operating Mode
You leave the configuration mode by pressing the “mode” button.
Pressing the button shortly:
Exits the configuration mode without projecting the current AS-i configuration.
Pressing the button for more than five seconds:
Exits the configuration mode and projects the actual AS-i configuration. Simultaneously the actual AS-i configuration is stored as nominal configuration
in the EEPROM.
If the system detects an AS-i slave with address zero on the AS-i, it can
not leave the configuration mode.
In the protected operating mode, only AS-i slaves that are projected and whose actual
configurations match the nominal configurations will be activated.
6.3.2 Configuration Errors in Protected Operating Mode
As long as there is no configuration error, the numeric display is turned off while in
protected operating mode. Otherwise, the that address a faulty assignment is displayed. A faulty assignment occurs when a slave has been recognized or projected
but cannot be activated.

AS-i/PROFIBUS Gateway
Operating the AS-i/PROFIBUS Gateway
If there are more than one faulty assignments the one that was first detected is displayed. Pressing the “set” button shortly displays the next higher faulty address.
Shortly appearing configuration errors are stored in the device (advanced AS-i diagnosis). The last error that occurred can be displayed by pressing the set button. If a
short AS-i power failure is responsible for the configuration error the display shows a
“39“.
6.4 Assigning an AS-i Address in Configuration Mode
AS-i can be put into operation in a very comfortable manner by using the Windows
software AS-i Control Tools (see chapter 9.1)(addressing directly or with the AS-i address assistant).
Furthermore you can use a hand held addressing device.
If you don’t have neither a PC nor a hand held addressing device, address assigning
of the AS-i slaves is also possible with the AS-i/PROFIBUS Gateway using the push
buttons. How it works is described as follows.
6.4.1 Assigning a Slave Address
(assigning an available address to a slave with address zero)
In configuration mode, the addresses of all detected slaves are displayed one after
the other. To display the next higher available operating address, press the “set” button shortly. Each time you press the “set” button, the next available address is displayed.
Chose the displayed address as your target address by pressing the button for more
than five seconds. The address display blinks. The master is ready for programming;
pressing the “set” button again addresses the connected slave with address zero to
the target (blinking address.
Any errors will be displayed by their error codes according to chapter 10. Otherwise,
the detected slaves are displayed again as described in chapter 6.2.
6.4.2 Erasing the Slave Address
AS-iIn configuration mode, the addresses of all recognized slaves are displayed one
after the other. By pressing and releasing the “set” button, the master displays the
next available address. If you press the button for more than five seconds while the
address of a detected slave is displayed, this slave is will get the address zero and
the display shows “00”.
When you release the button, the display continues to display the detected slaves.

AS-Interface
Operating the AS-i/PROFIBUS Gateway
6.5 Programming the Address in Case of Configuration Errors
6.5.1 Automatic Address Assignment
One of AS-i’s great advantages is the automatic address assignment. If
a slave fails, it can be replaced by one of the same type with address
zero. The master will detect the replacement and automatically
addresses the new slave with the address of the faulty one.
For automatic programming to work, some requirements must be met:
1.The AS-i master must be in the protected operating mode.
2.The “Auto_Address_Assign” release flag must be set.
3.Only one of the projected slaves may not be detected.
If these requirements are met, the AS-i master’s “prg enable” LED lights up and a
slave with address zero will be automatically assigned to the operating address of the
missing slave.
If the two slaves have different configuration data, i.e. are not of the
same type as far as AS-i is concerned, the automatic address assignment will not be carried out.
6.5.2 Manual Address Assignment
If several slaves fail, they cannot be replaced automatically by the AS-i
master. You must set their addresses manually. If this should not be
done via the Profibus interface (using the AS-i Control Tools) or with a
hand held addressing device, you can set them with the push buttons
and the figure display of the device.
In protected operating mode, wrong assignments are displayed as errors (see chapter
6.3). By pressing the “set” button, you can display all faulty assignments one after the
other. By pressing the “set” button for more than five seconds, you can select the currently displayed address as a potential target address, and the display starts to blink.
If the faulty slave was previously replaced by a slave with address zero, the new slave
can now be programmed for the blinking address by pressing the “set” key again. As
a requirement, the new slave’s configuration data must match the configuration data
for the blinking address.
After the address has been successfully set, the next faulty assignment is displayed
and the address assignment can begin from the start. Otherwise, the system displays
an error code (chapter 10). When all faulty assignment are eliminated the display is
