1. Introduction
The OM11 DeviceNet interface is an electronic module that allows you to connect the Keystone EPI2
electrical actuator to a DeviceNet network. The module has its own microprocessor and acts as a
pure bus interface without affecting the actuator control integrity. It is installed inside the actuator
housing and takes the electrical power from the actuator power supply module. The DeviceNet
network is fully isolated from the actuator electronics. For details about EPI2actuator the reference
manual is: EPI2Quarter-turn Electric Actuator IOM.
2. Operation and storage
The module is designed to work and to be stored in the same environment of the actuator.
Warning

4.3 Bus/hardwired mode selection
The DeviceNet interface manages the bus/hardwired mode selection by means of the input
terminal indicated with HW MODE. The physical input accepts from 24 to 125 V DC or AC, polarity
insensitive. When the input is left unconnected or no voltage is applied, the actuator is under bus
control from which is possible to send commands and read status.
When an appropriate voltage is applied to the HW MODE input, the actuator turns under
Hardwired control. In this condition the bus can only read actuator status while the actuator follows
the hardwired open and close controls connected to the terminal board. For further details see the
relevant wiring diagram and the user’s manual: EPI2Quarter-turn Electric Actuator IOM.
5. Brief DeviceNet description
DeviceNet is a low-level network that provides connection between industrial field devices
(sensors and actuators) and higher-level devices (controllers). DeviceNet uses CAN (Controller Area
Network) for its datalink layer, and CIP (Common Industrial Protocol) for the upper layers of the
network. The major physical and media characteristics of the DeviceNet are:
• Trunk-line / drop-line topology of the network;
• Support for up to 64 devices in a network (i.e. 1 master and 63 EPI2actuators);
• Node removal without altering the network behavior;
• Support of both network-powered and self-powered devices on the same network;
• Wiring error protection;
• Selectable data rate of 125 k baud, 250 k baud and 500 k baud.
• Adjustable power configuration to meet individual application needs;
• High current capability (up to 8 A at 24 V DC);
• Operation with off-the-shelf power supplies;
• Available power taps that allow the connection of several power suppliers;
• Build-in overload protection;
• Controller Area Network (CAN) technology for Media Access Control and Physical Signalling.
Drop length
Data rate Trunk distance Maximum Cumulative
125 k baud 500 meters 6 meters 156 meters
250 k baud 250 meters 6 meters 78 meters
500 k baud 100 meters 6 meters 39 meters
5.1 Network cable
To obtain the expected performances from the communication network the suitable cable must
be utilized. DeviceNet requires a specific cable composed of a Power pair, a Data Pair and a shield
with drain wire. DeviceNet defines different
cables to be used in the different parts of
the network:
• in the trunk line is normally used the
thick cable.
E.g. BELDEN 3082A:
1 pair 15 AWG 19x28 Tinned Copper –
Power pair
1 pair 18 AWG 19x30 Tinned Copper –
Data pair inner shield 100% coverage
• in the drop line is normally used the
thick cable. e.g. BELDEN 3084A
E.g. BELDEN 3084A:
1 pair 22 AWG 19x34 Tinned Copper –
Power pair
1 pair 24 AWG 19x36 Tinned Copper –
Data pair inner shield 100% coverage
5.2 Terminator
The DeviceNet network must be terminated to each end of the main trunk line with a 120 ohm
resistor across CAN_H and CAN_L data line.

7.2 DeviceNet MACID configuration
The DeviceNet interface module allows MACID setting both for manual configuration as for software
configuration by means of two ten-position BCD rotary switches as indicated in the figure.
The current setting is read in decimal representation:
MSB_ADD specifies the ten (1x, 2x, 3x, …); LSB_ADD specifies the unit (x1, x2, x3, …).
Manual configuration
When BCD rotary switches specify a valid DeviceNet MACID, i.e. a value from 00 to 63, the module
considers this value as the device MACID.
Software configuration
If the switches specify an invalid DeviceNet MACID, i.e. a value greater than 63, the module uses the
value stored in non-volatile memory and is ready for software configuration of MACID via specific
communication message.
Configuration procedure
To change the current value of the BCD rotary switches to set a different MACID, the user shall
follow this procedure:
• Move the dip switch ENA_CFG to the ON position: the ON_CFG LED is activated to indicate that
the actuator has entered Configuration Mode
• Set the new MACID via the rotary switches MSB_ADD and LSB_ADD.
E.g.: to set MACID = 28:
MSB_ADD. on position 2
LSB_ADD on position 8
• Press the pushbutton ENTER to confirm the new set: if the new MACID is correct the CFG_OK
LED turns ON
• Move the dip switch ENA_CFG on the OFF position to exit from Configuration Mode: the
DeviceNet interface module is reset to activate the new configuration.
Configuration procedure
To change the current value of the BCD rotary switch to set a different Data Rate, the user shall
follow this procedure:
• Move the dip switch ENA_CFG on the ON position: the ON_CFG LED turns ON to indicate that
the actuator is entered in Configuration Mode
• Set the new Data Rate on the rotary switches DATA_.
• Press the pushbutton ENTER to confirm the new set: if the new MACID is correct the CFG_OK
LED turns ON
• Move the dip switch ENA_CFG on the OFF position to exit from Configuration Mode: the
DeviceNet interface module is reset to activate the new setting.
7.3 DeviceNet communication speed configuration
The DeviceNet interface module allows also Date Rate setting via manual configuration (or software
configuration) by means of one ten-position BCD rotary switch DATA_RATE as indicated in the
figure.
Manual configuration
When BCD rotary switch specify one of the following valid DeviceNet Data Rate:
0: 125 Kbps
1: 250 Kbps
2: 500 Kbps
the module will work at the selected data rate.
Software configuration
If the switches specify any other invalid DeviceNet Data Rate, i.e. a value from 4 to 9, the module
uses the value stored in non-volatile memory and is ready for software configuration of Data Rate
via a specific communication message.
8. Bluetooth communication module
The OM11 module is provided with integrated Bluetooth module. In www.biffi.it you can download
A-Manager program to modify each settings by integrated Bluetooth module. After installation of
A-Manager program, please clic on ‘Operations’button and then clic on ‘Bluetooth Control’button
