The OM9 Probus DPV1 interface is an electronic module that allows you to connect
the Keystone EPI2 electrical actuator to a Probus DP network. The module has its own
microprocessor and control program. It works as a pure bus interface and does not affect
the actuator control integrity. It is installed inside the actuator housing and takes the
electrical power from the actuator power supply module.
The RS485 interface is located on the module board. The Probus network is fully isolated
from the actuator electronics. The OM9 Probus DPV1 is designed to support Probus
DPV0 cyclic communication and acyclic communication as per Probus DPV1 extension.
For details about EPI2 actuator, please refer to Installation, Operation and Maintenance
Manual for Keystone EPI2 electric actuator.
NOTE:
For decommissioning instructions, please refer to the relevant chapter in the EPI2 manual
ref. EBPRM-0091.

Section 3: Distinguish Old/New Models
It is important to distinguish between EPI2 old models and the new ones. To install the
board on base actuator, in fact, it is necessary to choose the correct mechanical parts
from the kit. Furthermore, the meaning of some data exchanged on the Probus interface
depends on model (old or new); differences will be explained in the following paragraphs.
Figures 3 and 4 allow to distinguish old version of EPI2 from the new version
(on the labels, the digits of Product Number are boxed); furthermore, the logic boards with
heatsink identies old version models, while logic boards without heatsink identies new
version models.

6.3 Probus/Hardwired Mode Selection
The EPI2 DPV1 interface manages the Probus/hardwired mode selection by means of the
input indicated with HW MODE. The physical input accepts any voltage from 24 - 125 V DC
or AC, polarity insensitive.
When no voltage is applied, the actuator is Probus controlled and it is possible to send
commands and read the status by Probus DP.
When an appropriate voltage is applied to the HW MODE input, the actuator runs under
hardwired control. In this condition, the Probus master can only read the actuator status,
while the actuator follows the hardwired Open and Close controls connected to the
terminal board.

Section 7: Probus DP Description

Installation, Operation and Maintenance Manual
Section 7: Probus DP Description
Probus is a vendor-independent, open eldbus standard used in a wide range of
applications in process automation. Vendor independence and openness are ensured
by the international standards EN 50170 and EN 50254. The DP communication
prole is designed for data exchange at the eld level. The central controllers (i.e., PLC)
communicate via a serial connection with eld devices (as sensors and actuators). Data
exchange is mainly cyclic. The central controller (called master) cyclically reads the
input information from the eld devices (called slaves) and cyclically writes the output
information to the slaves. In addition, the Probus DP provides communication services
for parameterization, alarm handling, and monitoring of intelligent eld devices. The
maximum number of master and slave devices in a bus segment is 32 without repeaters.
With repeaters, the number can be extended to 126 on one bus. The maximum cable
length depends on the speed of transmission. The higher the speed, the shorter is the
length. For instance, with baud rate 93.75 Kb/s, the max cable length is 1,200 m without
repeaters and 10,000 m with repeaters.
Mono-master or multi-master system conguration can be provided. Bus access is
controlled by a token passing procedure between masters and polling (master-slave
procedure) between master and slaves.

Section 8: RS485 Transmission Mode
Section 8: RS485 Transmission Mode
The EPI2 DPV1 interface uses a half duplex, multidrop, serial RS485 communication line.
The module communicates with the masters via its RS485 interface and the transmission
media consists of a shielded twisted pair cable. Transmission speed from 9.6 kbit/s to
1.5 Mbit/s is available. One unique transmission speed is allowed for all devices on the bus
when the system is running. All devices are connected in a bus structure. Up to 32 stations
(master and slaves) can be connected in one segment without repeaters. Repeaters can
be used to extend the number of devices up to 126 and to link the individual bus segment
in order to enlarge the network area. Table 1 shows the relationship between baud rate,
segment length and total bus length.
The bus must be terminated by an active bus terminator at the beginning and at the end
of each segment. Only two terminators in one bus segment must be provided. To ensure
error-free operation, both bus terminators must be powered. The maximum cable length
depends on the transmission speed. Cable lengths indicated in Table 1 are based on Type A
cable, as specied by the EN 50170, having the following characteristics.
• Impedance from 135 - 165 ohm
• Capacity < 30 pF/m
• Loop resistance 110 ohm/km
• Wire gauge 0.64 mm
• Conductor area > 0.34 mm
The use of cable of previously used type B is not recommended. The data lines must not
be reversed. Use of shielded cable is mandatory for having high system immunity against
electromagnetic disturbs. The shield should be connected to ground on both sides. The
data lines should be kept separate from all other cables. It should be laid in a separate,
conductive and earthed cable trunking. It must be ensured that there are no voltage
differences between individual nodes of Probus DP.

Section 9: EPI2 DVP1 Power-Up
Section 9: EPI2 DPV1 Interface Power-Up
The EPI2 DPV1 interface takes its electrical supply from the actuator power supply module.
The RS485 bus transceiver is isolated from the actuator electronics. Also, the voltage
supply of the bus termination is isolated. The bus termination is a crucial component
to ensure error-free operation; since the Probus terminations are active circuits, it is
important that they remain powered also when a part of the eld is powered off. Normal
practice recommends to use external terminations available on the market and to power
them by a separate, safe power supply. The EPI2 DPV1 interface is equipped with an
on-board bus termination that can be used when the actuator is at the beginning or at
the end of the bus segment. If the on-board termination is used, it is not possible to use
external termination, as well. The bus termination can be connected on the data lines by
means of a soldering pad.
Figure 37 shows the typical Probus wiring. The termination must be linked to the data
lines only if the actuator is at the beginning or at the end of the bus segment.

On power-up, the module checks the baud rate and then waits for the “parameterization”
telegram from the master. The parameterization message contains user information
needed for actuator operation and is listed in Section 10, Data Exchange
During Parameterization.
After parameterization, the module waits for the “conguration” telegram from the
master. The conguration message contains the number of input and output bytes
reserved in the memory of the master device for each slave. Only the number of bytes
determined in the conguration is transmitted between master and slave. This information
is called “module”.
EPI2 DVP1 Power-Up
The EPI2 DPV1 board implements the following modules:
Consistent is an attribute that specify the capability of the module to maintains data
consistency over the entire data length. In this way, the data will not change during
the reading by the Probus DP-Master. For example, if module 2 is selected, the output
telegram consists in 4 bytes, and the input telegram in 6 bytes.
When parameters and conguration are correct, the module enters in ‘data exchange
mode’ and starts with normal operation. The master cyclically sends commands to the
slave and read its status. Figure 38 shows the power-up ow diagram of a DP slave.

11.1 Cyclic Communications DPV0
11.1.1 Output Data
The structure of cyclic output data is as follows, depending on the module selected:
When this bit is set to 1, an open command is
issued to the actuator. The open command is
maintained for all the duration on the
Open command
Close command
Stop command

Set point
movement since the receiving of the bus
command until the open limit has been reached.
The open command is reset when a stop
command is received from the bus.
When this bit is set to 1, a close command is
issued to the actuator. The close command is
maintained for all the duration on the
movement since the receiving of the bus
command until the close limit has been reached.
The close command is reset when a stop
command is received from bus.
When this bit is set to 1, a stop command is
issued to the actuator. The stop command
received from the bus causes the reset of both
open and close command.
When this bit is set to 1, it enables the on-board
positioner. The positioner is enabled as long as
this bit is set to 1.
The set point received from the bus is used to
produce the open or close commands to the
EPI2 actuator as dened in Section 11.1.3,

11.1.3 Positioning Algorithm
A positioning algorithm (position closed loop control) is implemented on the EPI2 DPV1
interface card. Positioning function compares the position received from the base card
with the position request received from the bus. If the difference between “position
request and present position” is greater than the “dead band”, an open or a close
command is sent to the base card. Dead band is congurable via bus from 0.3 to 2.0%.
11.1.4 Diagnostic Message
The EPI2 DPV1 interface manages the diagnostic indication coming from the actuator as
stated by the Probus DPV1 standard. When the EPI2 DPV1 interface needs to notify a fault
to the master while in data exchange mode, it changes the function code in its response
message to “high priority”. During the next regular bus cycle, the master, in turn, sends
a “Slave_Diag” request that is answered with a “Slave_Diag” response. The availability of
specic diagnosis information is notied by Dia.Ext_Diag ag set to 1. Once the master
was able to catch the diagnosis information, it returns to the standard cyclic data exchange
mode. To notify the termination of the diagnosis incident, the EPI2_DPV1 interface send a
“high priority” response. The master answers with a “Slave_Diag” request that is followed
by a “Slave_Diag” response with Dia.Ext_Diag ag set to 0.

The EPI2 DPV1 board is equipped with a set of switches to allow the operator to congure
the Probus address. Furthermore, two soldering pads are available to connect the
Probus termination circuit to be used in case that the external termination is not available.
To perform the local setting on the EPI2 DPV1 board, it is necessary to follow carefully the
procedures explained in the Installation, Operation and Maintenance Manual for Keystone
EPI2 electric actuator, Section 6, Actuator Settings and Conguration.
12.1 Probus Address Setting
Probus address is congured by means of the switches indicated in the gure and located
on the EPI2 DPV1 interface soldering side, directly accessible when the control unit cover is
removed. To enter a new Probus address, the EPI2 actuator needs to be powered.
Conguration procedure:
• Move the dip switch ENA-CFG to the ON position; the CFG_ON LED is turned ON to
indicate that the actuator is entered in conguration mode.
• Set the new Probus address on the rotary switches UNIT and DEC and on the dip
switch HUNDR. E.g. address 028 corresponds to:
— HUNDR. on OFF position
— DEC. on position 2
— UNIT on position 8
• Press the push button ENTER to conrm the new settings; if the new address is
correct, the ACQ_CFG LED is turned ON.
• Move the dip switch CFG_ENA to the OFF position to exit from conguration
mode: the CFG_ON LED is turned OFF and the OM9 Probus DPV1 restarts with
the new address. It is not required to power down and start up the actuator.
