About Anybus Communicator 9 (124)
4 About Anybus Communicator
4.1 Serial Protocol Communication
4.1.1 Serial Protocol Types
The gateway features three distinct modes of operation for the subnetwork communication,
called Modbus RTU,Custom Request/Response and Custom Produce/Consume.
Modbus RTU
By default the Communicator uses the Modbus RTU serial protocol.
The Communicator uses Modbus transactions defined by the Modbus standard.
The Communicator acts as a client on the subnetwork, and the serial communication takes place
in a request/response fashion.
The nodes on the network are not permitted to issue messages unless they have been addressed
by the Communicator first.
Custom Request/Response
In this mode, you can define your own serial transactions to handle a wide range of custom serial
protocols.
The Communicator acts as a generic serial client on the subnetwork.
The serial communication takes place in a request/response fashion.
Custom Produce/Consume
In this mode, you can define your own serial transactions to handle a wide range of custom serial
protocols.
The Communicator may consume and/or produce messages on the subnetwork.
There is no client-server relationship between the nodes on the network, messages are
spontaneously produced or consumed when data is available.
Anybus®Communicator™User Manual SCM-1202-162 1.1 en-US

About Anybus Communicator 10 (124)
4.1.2 Serial Protocol Building Blocks
The following building blocks are used to describe the subnetwork communication.
Node
A node represents a single device on the subnetwork.
Each node can be associated with a number of transactions.
Nodes and Transactions
Transactions are based on standard Modbus RTU transactions (Modbus RTU serial protocol) or
transactions templates (Custom Request/Response or Produce/Consume serial protocol) and
define the data to be sent or received.
Each transaction has a number of parameters that need to be configured to define how data is
to be sent / received.
Frame Fields
The Frame editor is used to design custom transaction templates.
The Frame editor with Frame fields is available when either the Custom Request/Response or
Custom Produce/Consume serial protocol is enabled.
Anybus®Communicator™User Manual SCM-1202-162 1.1 en-US

About Anybus Communicator 11 (124)
Frame fields are low level entities used to compose transactions.
A frame field can represent a:
• fixed value, a constant
• range of values, limit objects
• block of data or a calculated checksum
Transaction Templates
The Transaction templates are available when either the Custom Request/Response or Custom
Produce/Consume serial protocol is enabled.
A transaction represents a complete serial telegram, and consists of a number of frame fields.
Each frame field is associated with a set of parameters controlling what is transmitted on the
subnetwork.
The transaction templates are stored in the Communicator and can be reused multiple times.
Anybus®Communicator™User Manual SCM-1202-162 1.1 en-US

About Anybus Communicator 12 (124)
Examples:
If you have a common read transaction. Then you can create one single transaction template for
the read transaction and reuse it multiple times times on your node(s).
If you have a function code in your protocol similar to a standard Modbus RTU transaction. Then
you can create a transaction template based on the Modbus RTU transaction for the read
operation. When you reuse the template on your node(s), you only have to change the function
code each time it is used.

About Anybus Communicator 13 (124)
4.2 How the Communication Works
The Communicator enables communication, data exchange, between one or more server devices
connected to a serial subnetwork and a client device connected to a high level network.
For example:
• The client device can be a PLC controller or a PC.
• A server devices can be a sensor, scanner, industrial robot or sniffer.
The Communicator main task is to cyclically send the transactions that the server(s) are
configured to execute, in order to request and transfer process data.
Anybus®Communicator™User Manual SCM-1202-162 1.1 en-US

About Anybus Communicator 14 (124)
Request process data
Request process data from the serial subnetwork nodes, specified in the Communicator
configuration, and make the process data available on the server interface and for the high level
network client device.
Transfer process data
Transfer process data from the high level network client device and make it available on the
server interface and for the serial subnetwork nodes included in the configuration.
Anybus®Communicator™User Manual SCM-1202-162 1.1 en-US

About Anybus Communicator 15 (124)
4.3 How the Data Exchange Works
The data exchanged between the Communicator and the serial subnetwork and the high level
network resides in the Communicator internal memory buffer.
To exchange data with the serial subnetwork, the high level network reads and writes data to the
Communicator internal memory buffer.
The same memory locations are exchanged on the serial subnetwork.
The memory locations are specified when configuring the Communicator, using the
Communicator built-in web interface.
The Communicator internal memory buffer is divided into two areas: Input data and Output data.
Input Data
This Input data area is read by the high level network.
The Communicator can handle up to 1500 bytes input data.
Output Data
The Output data area is read/written by the high level network.
The Communicator can handle up to 1500 bytes output data.
4.4 Data Integrity
A snapshot of the process data buffer between the Modbus Client and the server interface is
used during the operation of executing all the transactions within one cycle.
When the cycle is completed, the process data available on the server interface is updated and a
new snapshot is created for the next cycle.
