result in corruption of software or damage to equipment/property
The information icon alerts the reader to pertinent facts and conditions
The tip icon indicates advice on, for example, how to design your project or how to
use a certain function
Although Warning notices are related to personal injury, and Caution notices are associated
with equipment or property damage, it should be understood that the operation of damaged
equipment could, under certain operational conditions, result in impaired process

2. Introduction
The Digital Gateway is an industrial PC equipped with interface cards and ports re-quired for
communication internally to UMC and externally to process control systems as well as to the
CMES Edge which provides condition monitoring features and functions as well as edge con-
nectivity to ABB Ability™ cloud based solutions.
Figure 1: Digital Gateway
One Digital Gateway can communicate internally to up to 128 UMC / field devices by Modbus
TCP. If more than 128 UMC / field devices are installed, then additional Digital Gateway have
to be configured.

PROFIBUS STANDARD INTRODUCTION
81TGC908004
2.2 PROFIBUS Standard
PROFIBUS is a manufacturer-independent Fieldbus standard for applications in manufactur-
ing, process and building automation. PROFIBUS technology is described in fixed terms in
DIN 19245 as a German standard and in EN 50170 / IEC 61158 as an international standard.
The PROFIBUS standard is thus available to every provider of automation product.
The PROFIBUS family is composed of three types of protocol, each of which is used for differ-
ent tasks. Of course, devices with all three protocols can communicate with each other in a
complex system by means of a PROFIBUS network.
The three types of protocols are: PROFIBUS FMS, DP and PA. Only the two protocol types DP
and PA are important for process automation, whereas only DP is used in LVS Digital
PROFIBUS DP: PROcess Fieldbus for the Decentralized Periphery
The PROFIBUS DP (RS 485) is responsible for communication between the Controller level of a
process automation system and the decentralized periphery in the field. One feature of
PROFIBUS DP is its high speed of transmission up to 12 Mbit/s.
Digital Gateway supports transmission speed up to 1.5 Mbit/s only.
2.3 PROFIBUS DP-V0
2.3.1 Cyclic Data Communication
The data communication between the DPM1 (DP Master Class 1) and its assigned slaves is
automatically handled by the DPM1 in a defined, recurring sequence. With each user data
transfer, the master can write up to 244 bytes of output data to the slave and read up to 244
bytes of input data from the slave. The Data is read and written synchronously in one
procedure.
Figure 3 Cyclic User Data Transmission in DP
The data communication between the DPM1 and the slaves is divided into three phases:
parameterization, configuration and data transfer. Before the master includes a DP slave in
the data transfer phase, a check is run during the parameterization and configuration phase
to ensure that the configured set point configuration matches the actual device
configuration. During this check, the device type, format and length information and the
number of inputs and outputs must also correspond. This provides you with reliable
protection against parameterization errors

INTRODUCTION PROFIBUS DP-V0
1TGC908004 9
2.3.2 Diagnostic
In addition to the cyclic data the PROFIBUS slave unit provides diagnostic data. With this
diagnostic data the slave can indicate errors or warnings on the slave unit, the I/O-units or
the I/O-channels. Some diagnostic data is generic and defined by the PNO. But most of the
diagnostic data is manufacturer specific.
An example for generic diagnosis is: Slave not ready, Parameter fault and Watchdog
monitoring.
Digital Gateway supports only generic diagnostic. Extended (manufacturer specific)
diagnostic is not used.
2.3.3 Sync and Freeze Mode
In addition to the normal cyclic communication between the DPM1 (DP Master Class 1) and
the assigned slaves, a master can send the control commands sync and freeze via multicast
to a group of slaves.
With the sync-command the addressed slaves will freeze the outputs in their current state.
New output values received by the master will be stored while the output states remain
unchanged. The stored output data are not sent to the outputs until the next sync command
is received. The Sync mode is terminated with the “unsync” command.
In the same way, a freeze command causes the addressed slaves to enter freeze mode. In this
mode, the states of the inputs are frozen at their current value. The input data are not
updated again until the master sends the next freeze command. Freeze mode is terminated
with the “unfreeze” command
Digital Gateway does not support Sync Mode and Freeze Mode even if it is se-
lectable in GSD configuration.
2.3.4 DP Master Class 1 (DPM1) and Class 2 (DPM2)
The DP master class 1 is the master that is in cyclic data transmission with the assigned
slaves. To get into the cyclic communication the DPM1 has to configure the slave before.
The DP master class 2 is used for engineering and configuration. It does not have cyclic data
transmission with the slave devices. Normally a DPM2 is only connected temporarily to the
bus. A DPM2 can have class 2 communication to the slave devices before the slaves are
configured via DPM1 and cyclic communication is active.
Digital Gateway supports communication with DPM1 only.
2.3.5 Monitoring the DP-V0 Communication
The cyclic communication between the DPM1 and the slaves is monitored by the master and
the slaves itself. If the DPM master unit detects a failure in the communication with a slave, it
will indicate the corresponding slave as disturbed.
On slave side the communication with the master is controlled via the watchdog. If no data
communication with the master occurs within the watchdog control interval, the slave auto-
matically switches its outputs to the fail-safe state.
PROFIBUS watchdog must be enabled for master and failsafe functionality must be
parameterized for Digital Gateway.

PROFIBUS DP-V1 INTRODUCTION
10 1TGC908004
2.4 PROFIBUS DP-V1
2.4.1 Acyclic Data Communication
The key feature of version DP-V1 is the extended function for acyclic data communication.
The acyclic data communication is mainly used for configuration and parameterization
purpose. With the acyclic DP-V1 read and write services the master can read or write any
desired data to and from the slave. The data is addressed by slot, index and length. Each data
block can be up to 240 bytes.
Figure 4 Acyclic Communication in DP-V1: Read Service
The transmission of acyclic data is executed in parallel to the cyclic data communication, but
with lower priority. Acyclic services are operated in the remaining time at the end of the DP-
V0 cycle.
