3.1.4 Topology
The MCA 121 features a build-in Ethernet-switch, thus having two Ethernet RJ-45 connectors. This enables the possibility for connecting several EtherNet/IP options in a line topology as an alternative to the typical star-topology.
The two ports are equal, in the sense that they are transparent for the option. If only one connector is used, either port can be used.

NOTE
For line topology please refer to section: “Recommended design rules” In a line topology all frequency converters must be powered, either by mains or by their 24 V DC option cards, for the build-in switch to work.
NOTE
Please observe that mounting frequency converters of different power-sizes in a line topology may result in unwanted power-off behaviour.
Smaller frequency converters discharge faster than bigger ones. This can result in loss of link in the line topology, which may lead to control word timeout.
To avoid this, mount the frequency converters with the longest discharge time first in the line topology.

3.1.5 Network
It is of high importance that the media chosen for Ethernet data transmission are suitable. Usually CAT 5e and 6 cables are recommended for industrial applications. Both types of cable are available as Unshielded Twisted Pair and Shielded Twisted
Pair. Generally shielded cables are recommended for use in industrial environments and with frequency converters.
A maximum cable-length of 100 m is allowed between switches.
Optical fibres can be used for gapping longer distances and providing galvanic isolation.
For connecting EtherNet/IP devices both hubs and switches can be used. It is, however, recommended always to use suitable industrial graded Ethernet switches. Hubs should always be avoided, since they will lead to collisions. For more information regarding IP-switching, please refer to section: IP Traffic in this manual.

3.1.6 Recommended Design Rules
While designing Ethernet networks special attention and caution must be taken regarding active network components.
While designing a network for line topology it is important to notice that a small delay is added with each every switch in the line.
It is not recommended to connect more than 32 frequency converters in a line at any API. Exceeding the recommended design rules, may result in failing communication.

3.1.7 EMC Precautions
The following EMC precautions are recommended in order to achieve interference-free operation of the Ethernet network.
Additional EMC information is available in the frequency converter Design Guide.
NOTE
Relevant national and local regulations, for example regarding protective earth connection, must be observed.
The Ethernet communication cable must be kept away from motor and brake resistor cables to avoid coupling of high frequency noise from one cable to the other. Normally a distance of 200 mm (8 inches) is sufficient, but maintaining the greatest possible distance between the cables is recommended, especially where cables run in parallel over long distances.
When crossing is unavoidable, the Ethernet cable must cross motor and brake resistor cables at an angle of 90 degrees.

4.1.4 IP traffic
The use of Ethernet based network for industrial automation purposes, calls for careful and thorough network design. Especially the use of active network components like switches and routers requires detailed know-how about the behaviour of IP traffic.
Some important issues:
Multicast
Multicast traffic; is traffic that is addressed to a number of recipients. Each host processes the received multicast packet to determine if it is the target for the packet. If not, the IP package is discarded. This causes an excessive network load of each node in the network since they are flooded with multicast packages. The nature of EtherNet/IP traffic is that all Originator-to-Target traffic is Unicast
(point-to-point) but Target-to-Originator traffic is optional
Multicast. This enables that several listen only -connections can be made to a single host.
In switched networks hosts also have the risk of becoming flooded with multicast traffic. A switch usually forwards traffic by MAC address tables build by looking into the source address field of all the frames it receives.
A multicast MAC address is never used as a source address for a packet. Such addresses do not appear in the MAC address table, and the switch has no method for learning them, so it will just forward all multicast traffic to all connected hosts.
IGMP
IGMP (Internet Group Management Protocol) is an integrated part of IP. It allows hosts to join or leave a multicast host group. Group membership information is exchanged between a specific host and the nearest multicast router.
For EtherNet/IP networks it is essential that the switches used, supports IGMP Snooping. IGMP Snooping enables the switch to “listen in" on the IGMP conversation between hosts and routers. By doing this the switch will recognise which hosts are members of which groups, thus being able to forward multicast traffic only to the appropriate hosts.
Redundancy
For an Ethernet network to function properly, only one active path can exist between two nodes. Spanning-Tree
Protocol is a link management protocol that provides path redundancy while preventing undesirable loops in the network.
When loops occur, some switches see stations appear on both sides of it self. This condition confuses the forwarding algorithm and allows for duplicate frames to be forwarded.
Spanning tree
To provide path redundancy, Spanning-Tree Protocol defines a tree that spans all switches in an extended network. Spanning-Tree Protocol forces certain redundant data paths into a standby (blocked) state. If one network segment in the Spanning-Tree Protocol becomes unreachable, or if Spanning-Tree Protocol costs change, the spanning-tree algorithm reconfigures the spanning-tree topology and re-establishes the link by activating the standby path.
Spanning-Tree Protocol operation is necessary if the frequency converters are running in a ring/redundant line topology.

How to Control
5 How to Control
MCA 121 EtherNet/IP
5.1 How to Control
5.1.1 I/O Assembly Instances
I/O Assembly Instances are a number of defined process control objects with defined content comprising control and status information.
Unlike DeviceNet it is possible to run with asymmetrical instances. E.g. 101/153 = 8 bytes/20 bytes.
It is not possible to mix instances across profiles, e.g. 20/100. Assembly instances must be consistent to the: ODVA or FC profile.
The controlling instance can be read in par. 12-20, Control Instance .

5.1.7 Change of State, COS
The event controlled operation mode is used to minimize network traffic. Messages are transmitted only if a defined state or value has changed. The condition for triggering a COS message, is determined by the insertion of COS-filters ( 12-38 COS
Filter ), for each bit in the different PCD-words.
The filter acts like a logical AND-function: If a bit in the filter is set to “1”, the COS-function triggers when there is a change to the corresponding bit for the PCD-word.
Parameter 12-38 COS Filter can be used to filter out undesired events for COS. If a filter bit is set to 0, the corresponding I/0
Instance bit will be unable to produce a COS message. By default, all bits in the COS filters are set to 0.
In order to signal that the connection has not been interrupted, or the device is not powered off, a Heartbeat Message is transmitted within a specified time interval (Heartbeat Interval). This interval is defined in Attribute Heartbeat Time of the connection object, Class 0x01.
To prevent the device from producing heavy network traffic when a value changes frequently, a Production Inhibit Time is defined in 12-37 COS Inhibit Timer . This parameter defines the minimum time between two COS messages. If 12-37 COS
Inhibit Timer is set to 0, the Production Inhibit Timer is disabled.

NOTE
In 8-56 Preset Reference Select select a selection is made to define how Bit 00/01 gates with the corresponding function on the digital inputs.
Bit 02, DC brake:
Bit 02 = ‘0’ leads to DC braking and stop. Braking current and duration are set in 2-01 DC Brake Current and 2-02 DC
Braking Time . Bit 02 = ‘1’ leads to ramping, 3-41 Ramp 1
Ramp up Time
Bit 03, Coasting:
Bit 03 = ‘0’ causes the frequency converter to immediately
"let go" of the motor (the output transistors are "shut off"), so that it coasts to a standstill.
Bit 03 = ‘1’ enables the frequency converter to start the motor if the other starting conditions have been fulfilled.
NOTE
In 8-50 Coasting Select a selection is made to define how
Bit 03 gates with the corresponding function on a digital input.
Bit 04, Quick stop:
Bit 04 = ‘0’ causes a stop, in which the motor speed is ramped down to stop via 3-81 Quick Stop Ramp Time .
Bit 05, Hold output frequency:
Bit 05 = ‘0’ causes the present output frequency (in Hz) to freeze. The frozen output frequency can then be changed only by means of the digital inputs ( 5-10 Terminal 18
Digital Input to 5-15 Terminal 33 Digital Input ) programmed to Speed up and Speed down .
NOTE
If Freeze output is active, the frequency converter can only be stopped by the following:
• Bit 03 Coasting stop
• Bit 02 DC braking
• Digital input ( 5-10 Terminal 18 Digital Input to
5-15 Terminal 33 Digital Input ) programmed to DC braking , Coasting stop or Reset and coasting stop

Bit 06, Ramp stop/start:
Bit 06 = ‘0’ causes a stop, in which the motor speed is ramped down to stop via the selected ramp down parameter. Bit 06 = ‘1’ permits the frequency converter to start the motor, if the other starting conditions have been fulfilled.
NOTE
In 8-53 Start Select Start select a selection is made to define how Bit 06 Ramp stop/start gates with the corresponding function on a digital input.
Bit 07, Reset:
Bit 07 = ‘0’ no reset. Bit 07 = ‘1’ resets a trip. Reset is activated on the leading edge of the signal, i.e. when changing from logic ‘0’ to logic ‘1’.
Bit 08, Jog:
Bit 08 = ‘1’ causes the output frequency to be determined by 3-19 Jog Speed [RPM] .
Bit 09, Selection of ramp 1/2:
Bit 09 = ‘0’ means that ramp 1 is active ( 3-40 Ramp 1 Type to 3-47 Ramp 1 S-ramp Ratio at Decel. Start ). Bit 09 = ‘1’ means that ramp 2 ( 3-50 Ramp 2 Type to 3-57 Ramp 2 Sramp Ratio at Decel. Start ) is active.
Bit 10, Data not valid/Data valid:
This bit tells the frequency converter whether the control word is to be used or ignored. Bit 10 = ‘0’ causes the control word to be ignored, Bit 10 = ‘1’ causes the control word to be used. The control word is always contained in the telegram, regardless of which type of telegram is used, so this function is useful for ‘turning off’ the control word when not required for updating or reading parameters.
Bit 11, Relay 01:
Bit 11 = ‘0’ Relay not activated. Bit 11 = ‘1’ Relay 01 activated, provided Control word bit 11 has been chosen in
5-40 Function Relay .
Bit 12, Relay 02:
Bit 12 = ‘0’ Relay 02 has not been activated. Bit 12 = ‘1’
Relay 02 has been activated, provided Control word bit 12 has been chosen in 5-40 Function Relay .

1-25 Motor Nominal Speed
3-02 Minimum Reference
3-03 Maximum Reference
All references provided to the frequency converter are added to the total reference value. If a reference is to be controlled by thefieldbus only, ensure that all other reference inputs are zero.
This means that digital and analogue input terminals should not be used for reference signals. The default setting (0%) should be maintained for preset references in 3-10 Preset Reference .
CAUTION
If the bus speed reference is negative, and the control word contains a run reverse signal, the frequency converter will run clockwise (- - is +).
MAV is scaled in the same way as the reference.

Table 7.2 NS1 + NS2: Network Status (one per port)
Flashing red/ green
Check: Link Status
The status of the Ethernet link cannot be directly identified by means of the LEDs, if no CIP connection is established.
Use 12-10 Link Status to verify presents of the link.
Use
to verify that the link is steady present.
The parameter will show the duration of the present link, and preset to 00:00:00:00 if the link is broken.
Check: Cabling
In rare cases of cabling mis-configuration, the option might show the presents of a link, but no communication is running.
Exchange the cable in doubt.
Check: IP Address
Verify that the option has a valid IP address (please refer to section: IP Settings) in 12-01 IP Address . If the option has identified a duplicate IP Address NS LEDs will light steady red. If the option is set up for BOOTP or DHCP, verify that a
BOOTP or DHCP server is connected in 12-04 DHCP Server . If no server is connected, the parameter will show:
000.000.000.000.
7.1.2 Alarm Word and Warning Word
Alarm word and warning word are shown in the display in Hex format. If there is more than one warning or alarm, a sum of all warnings or alarms will be shown. Warning word and alarm word are displayed in 16-90 Alarm Word to 16-95 Ext. Status
Word 2 . For more information on the individual alarms and warnings, please refer to the frequency converter Design Guide.
38 MG.90.J3.02 - VLT ® is a registered Danfoss trademark
Troubleshooting MCA 121 EtherNet/IP
NOTE
Please note that the availability of the individual alarms and warnings are dependent on the frequency converter type.
Warning and Alarm Messages
There is a clear distinction between alarms and warnings. In the event of an alarm, the frequency converter will enter a fault condition. After the cause for the alarm has been cleared, the master must acknowledge the alarm message in order to start operation of the frequency converter again. A warning, on the other hand, may appear when a warning condition arises, then disappear when conditions return to normal without interfering with the process.
Warnings
All warnings within the frequency converter are represented by a single bit within a warning word. A warning word is always an action parameter. Bit status FALSE [0] means no warning, while bit status TRUE [1] means warning. Each bit status has a corresponding text string message. In addition to the warning word message the master will also be notified via a change in the status word.
Alarms
Following an alarm message the frequency converter will enter a fault condition. Only after the fault has been rectified and the master has acknowledged the alarm message by a bit in the Control Word, can the frequency converter resume operation. All alarms within the frequency converter are represented by a single bit within an alarm word. An alarm word is always an action parameter. Bit status FALSE [0] means no alarm, while bit status TRUE [1] means alarm. In CIP, Alarms are divided in to two categories:
-
Major Recoverable Faults
Major Unrecoverable Faults
Please refer to the following sections for a classification of the specific faults.

8.1.1 Supported CIP Objects
As in all implementations of CIP, EtherNet/IP shares the common Object Model. Objects are a common method to describe the specific application implemented in a device.
Data is structured in Classes, Instances and Attributes:
A class is a group of objects with the same structure. These groups of objects within a class are called instances. Every instance provides the same data elements called attributes. Each class provides services to access data or to change the state of an object.
