Chapter 1
About the AnyBus-M AS-Interface
The AnyBus-M AS-I Master implements all functionality of the Reduced Extended Master (M2e) profile
as well as some functions of the Full Extended Master(M1e) profile.
The module can manage up to 62 AS-I slaves and it complies to the AS-Interface 2.1 specification. It
supports analog slaves according to slave profiles 7.3 and 7.4 (Consult the AS-Interface Slave Profiles
Specification for more information), and provides data exchange using the standard AnyBus-S applica-
tion interface. Additionally, the module features dedicated mailbox commands for accessing 7.4 slaves.
As for all AnyBus-M modules it is also possible to configure the network via the application interface.
Features
• Manage up to 62 slaves
• Up to 248 digital inputs and 186 digital outputs
• Up to 124 (16 bit) analog values
• Galvanically isolated bus electronics
• Easy to use, text based Configuration Interface via on board RS232 port
• Automatic Slave 0 Address Programming
• Complete access to network configuration via application interface
• Analog slave profile 7.1 and 7.2
• Analog slave profile 7.3 and 7.4
Compatible Products
This product is a member of the AnyBus concept of interchangeable fieldbus modules. This makes it
fully interchangeable with any fieldbus system supported by the AnyBus-M platform.

About the AnyBus-M AS-Interface 1-2
Overview
Connectors
Application Connector
The application connector features a standard AnyBus-M 2kbyte parallel DPRAM interface. For further
information, please consult the general AnyBus-M Design Guide.
AS-Interface Connectors
The module supports both 5.08 pluggable screw connectors and board to board connectors.
For more information about connectors and pin assignments, see Appendix B-1 “Connectors”
Configuration Interface
This Configuration Interface provides a simple text based user interface for use with a PC. No special
software is required except for a standard terminal emulatior.
For connector pinout and cable schematic, see Appendix B-1 “Connectors”

Chapter 2
Software Overview
Accessing the application DPRAM follows the standard AnyBus access-method. More information is
found in AnyBus-S parallell design-guide.
The command interface that is used to control the module consists of the following items:
•I/ODataArea
This area holds the actual network input and output data. The data can be presented in both byte
and nibble mode.
• Fieldbus Specific Area
This area holds general status information and information about each slave on the network.
• Mailbox Interface
This interface is used for network configuration and analog slave profile 7.3/7.4 handling. Note
that this interface cannot be accessed when using the serial Configuration Interface.
• Configuration Interface (RS232)
This interface generally provides the same settings as the Mailbox Interface.
Initialisation Sequence
• Send Start Init
(Wait for response)
• Send AnyBus Init (In total length = 64, Out total length = 64)
(Wait for response)
• Send End Init
(Wait for response)
• Send Set Running / Idle Mode and Set Data Representation
(Wait for response)
The module is now ready to exchange data on the network.
(For more information regarding module initialisation, consult the AnyBus-M Design Guide)
Operating Modes
The module offers two modes of operation; Configuration Mode and Protected Mode. For network se-
curity reasons, some functions that are available in Configuration Mode are not available in Protected
Mode and vice versa.
• Configuration Mode
All slaves attached to the network are active instantly.
• Protected Mode
Slaves must be detected and configured in order to become active. The mailbox command
MB_SaveConfig is not allowed in this mode.

Software Overview 2-2
I/O Data
The I/O data from the AS-Interface network can be devided into two categories:
•DigitalI/O
•AnalogI/O
Digital I/O
Digital I/O data is available in the Input and Output Data areas. The data can be presented in two ways;
Nibble and Byte. In Byte mode, each byte in the I/O area represents a slave on the nework, while in
Nibble mode each byte holds data for two slaves.
The way data is presented can be set either using mailbox commands or via the onboard Configuration
Interface.
• Data representation in byte mode:
In this mode, the data for each slave is located in the lower nibble of each byte.
• Data representation in nibble mode:
(Even slaves = high nibble, Odd slaves = low nibble)
Analog I/O
• Slave profiles 7.1 and 7.2
Values are read/written by the application software using I/O data directly in the input / output
areas. The application has to access each slave according to the special sequence defined in the
specification for analog slaves, profiles 7.1 and 7.2.
• Slave profiles 7.3 and 7.4
Analog values are be read/written by the application software using dedicated mailbox com-
mands; the number of slaves supported is 32 and starts with slave address 1 to 31.
The application is responsible for polling the detected analog 7.3 and 7.4 profile slaves when new
data is required.

Chapter 3
Configuration Interface (RS232)
This interface provides a simple text baseed user interface via the onboard RS232 interface. All network
configuration parameters are available using a standard terminal emulator such as the Windows Hyper-
terminal.
Note that data exchange is halted and no mailbox activity is possible while using this interface.
The interface uses the following communication settings:
Terminal emulation: ASCII
Baudrate: 38400
Databits: 8
Stopbits: 1
Parity: None
Flowcontrol: None

Mailbox Interface
This chapter describes the fieldbus specific mailbox commands in the module. Consult the AnyBus-S
Design Guide for more information regarding mailbox functionality. Note that this interface cannot be
accessed when using the serial Configuration Interface.
Fault and Status Information
When a mailbox command cannot be processed the Message Information register in the header of the
response will indicate that an error occurred. Consult the AnyBus-S Design Guide for more information.
If the error code is ‘Invalid Other’ (Fh), extended error information is available in the Fault Information
register (Extended word 8).
The fault codes in the Fault Information register are:
Register Value Name Description
0000h OK
0001h BUSY
0002h WRONG_SLAVE_ADDR
0003h NOT_IN_LAS
0004h SLAVE_0_EXIST
0005h BUS_ERROR
0006h EEPROM_ERROR
0007h UNKNOWN
