Please change the administrator password in order to protect yourself from unwanted configuration changes by anyone else. To do so, select the admin account in the drop-down box and enter the new password. If the administrator password is left empty, password protection is turned off and everyone can access the device without entering a password.
Click on Change password to activate the change.
4.2 Device Configuration
The device configuration pages allow viewing and changing the device settings of the
LINX. Here are some general rules for setting IP addresses, port numbers, and time values:
An empty IP address field disables the entry.
An empty port number field sets the default port number.
An empty time value field disables the time setting.
4.2.1 System Configuration
The system configuration page is shown in Figure 39. This page allows configuring the
device‘s system time and other system settings. The TCP/IP Configuration link is a shortcut to the Ethernet port configuration. Follow that link to change the IP settings of the device.
The time sync source can be set to auto , manual , NTP , BACnet , or LonMark . In the auto mode, the device switches to the first external time source that is discovered. Possible external time sources are NTP, BACnet, LonMark. The option manual allows setting the time manually in the fields Local Time and Local Date . In manual mode, the device does not switch to an external time source. Note, that if NTP is selected, the NTP servers have to
be configured on the IP Configuration page (see Section 4.2.2).
The time zone offset must be defined independently of the time source. It is specified as the offset to GMT in hours and minutes (e.g., Vienna/Austria is +01:00, New York/USA is
-06:00). For setting the daylight saving time (DST) predefined choices are offered for
Europe and USA/Canada. DST can be switched off completely by choosing none or set manually for other regions. In that case, start and end date of DST must be entered in the fields below.
Version 4.0 LOYTEC electronics GmbH

Figure 39: System Configuration Page, e.g., for Vienna, Austria.
The next section on the page allows configuring the device‘s earth position. This setting defines the longitude, latitude and elevation of the device. The latitude and longitude are entered as degrees, minutes, and seconds. The altitude is entered in meters height above sea level. This setting is used for an astronomical clock. For fixed locations such as a building, the position can be entered on this page.
For generating CSV files for trend logs, alarm logs, etc., the delimiter for those CSV files can be configured. This setting can be changed between a comma ‗,‘ and a semi-colon ‗;‘.
The change takes effect immediately for all files generated by the device.
4.2.2 Backup and Restore
A configuration backup of the device can be downloaded via the Web interface. Press the
backup link as shown in Figure 40 to start the download. The device assembles a single file
including all required files. A file requestor dialog allows specifying the location where the backup file shall be stored.
To restore the device settings, simply select a previously generated backup file in the
Restore Configuration section of the page by clicking the button next to the Filename field. Then press the Restore button.
The backed up configuration data consists of:
Device settings (Passwords, IP settings, e-mail config, etc.),

4.2.3 Port Configuration
This menu allows configuring the device‘s communications ports. For each communication port, which is available on the device and shown on the label (e.g., Port 1, Port 2 Ethernet), a corresponding configuration tab is provided by the Web UI. An example is shown in
Figure 41. Each port tab contains a selection of available communication protocols. By
selecting a checkbox or radio button the various protocols can be enabled or disabled on the communication port. Some ports allow exclusive protocol activation only, other ports (e.g., the Ethernet port) allow multiple protocols bound to that port.
Figure 41: Port Configuration Page.
When selecting a protocol on a communication port, the protocol‘s communication parameters are displayed in a box on the right-hand side. To save the settings of the currently opened protocol, click the Save Settings button. Pressing Get Settings retrieves the current settings from the device.
4.2.4 IP Configuration
The TCP/IP configuration is done under the Ethernet port tab as shown in Figure 42. The
mandatory IP settings, which are needed to operate the device, are marked with a red asterisk (IP address, netmask, gateway). The Enable DHCP checkbox switches between manual entry of the IP address, netmask, and gateway address, and automatic configuration from a DHCP server.
Version 4.0 LOYTEC electronics GmbH
L-INX User Manual 58 LOYTEC
Hostname and Domainname are optional entries and can be left empty. For some DHCP configurations it may be necessary to enter a hostname. Please contact your system administrator on how to configure DHCP to acquire an IP address. Further, you can configure up to 3 Domain Name Servers.
Version 4.0
Figure 42: IP Configuration Page.
The device comes configured with a unique MAC address. This address can be changed in order to clone the MAC address of another device. Please contact your system administrator to avoid MAC address conflicts.
The device can be configured to synchronize its clock with NTP time. Enter the IP address of a primary and, optionally, a secondary NTP server. The device will use NTP as a time source if the time sync source in the system configuration page is set to NTP (see Section
NTP status below the NTP server settings displays the current NTP synchronization status ( out-of-sync , or in-sync ).
If the device is operated with a 10 Mbit/s-only hub, the link speed should be switched from
Auto Detect to 10Mbps/Half-Duplex . With modern 100/10 Mbit/s switches, this setting can be left at its default.
Other standard protocols that are bound to the Ethernet interface are FTP, Telnet, and
HTTP (Web server). By deselecting the checkbox, those protocols can be individually disabled. The standard UDP/TCP ports can be changed in the respective protocol settings.
An example for the FTP server is shown for FTP in Figure 43. The FTP server is used for
instance to update the firmware (see Section 15.1) or to upload a new data point
configuration. Note that HTTP for the Web server can only be disabled on the console interface or by using the device configuration of the Configurator.

The CEA-709 protocol can be enabled on the device‘s ports Port1, Port2, etc. if available.
To enable it, click the CEA-709
radio button as shown in Figure 45. Note, that depending
on the device model, other protocols on the same port will be disabled in this case. The protocol settings box on the right-hand side displays the current transceiver settings.
Figure 45: CEA-709 Configuration Page.
4.2.7 CEA-852 Device Configuration
The CEA-852 protocol is only available on the Ethernet port. To enable CEA-852 on the device, select the CEA-852 (CEA-709 over IP) checkbox on the Ethernet tab of the port configuration page. Please note that on device models without a router or a proxy, the
CEA-709 protocol on other ports will be disabled (e.g., LINX-100).
The CEA-852 protocol settings are displayed in the settings box on the right-hand side as
shown in Figure 46. Typically, the device is added to an IP channel by entering the relevant
information on a configuration server. The configuration server then contacts the CEA-852 device of the L-INX and sends its configuration.
Version 4.0 LOYTEC electronics GmbH
L-INX User Manual 60 LOYTEC
Version 4.0
Figure 46: CEA-852 Device Configuration Page.
The field Config server address and Config server port display the IP address and port of the configuration server, which manages the L-INX and the IP channel. The field Config client port represents the IP port of the LINX‘s CEA-852 device. This setting should be left at its default (1628) unless there are more than one CEA-852 devices operating behind a single NAT router. Please refer to the L-IP User Manual [1] to learn more about NAT configuration.
In the field Device name the user can enter a descriptive name for the LINX, which will appear in the IP channel to identify this device. You can enter a device name with up to 15 characters. It is recommended to use unique device names throughout the IP channel.
The Channel mode field reflects the current channel mode of the CEA-852 device. It is configured by the configuration server. If there are any two devices in the channel which use the same IP address but different ports (e.g., multiple devices behind one NAT router) the channel switches to Extended NAT mode . Please refer to the L-IP User Manual [1] to learn more about configuring the Extended NAT mode in the configuration server.
The configuration server sets the SNTP server addresses and the Channel timeout .
The filed Escrow timeout defines how long the CEA-852 device on the L-INX waits for out-of-sequence CEA-852 data packets before they are discarded. Please enter the time in ms or ‗0‘ to disable escrowing. The maximum time is 255 ms.
The field Aggregation timeout defines the time interval in which multiple CEA-709 packets are combined into a single CEA-852 data packet. Please enter the time in ms or ‗0‘ to disable aggregation. The maximum time is 255 ms. Note that disabling aggregation will negatively affect the performance of the CEA-852 device of the LINX.
The field MD5 authentication enables or disables MD5 authentication. Note that MD5 authentication cannot be used together with the Echelon‘s i .
LON 1000 since the i .
LON 1000 is not fully compliant with the CEA-852 authentication method. MD5 can be used with the i .
LON 600. In the following field MD5 secret enter the 16-byte MD5 secret.
Note that for security purposes the active MD5 secret is not displayed. You may enter the
16 bytes as one string or with spaces between each byte, e.g., 00 11 22 33 44 55 66 77 88
99 AA BB CC DD EE FF.
LOYTEC electronics GmbH
L-INX User Manual 61 LOYTEC
Also note that entering the MD5 secret on the Web interface may pose a security risk. Since the information is transmitted over the network it can be subject for eavesdroppers on the line. It is recommended to use a cross-over cable.
In the field Location string the user can enter a descriptive test which identifies the physical location of the LINX. A location string can have a maximum length of 255 characters. This is optional and for informational purposes only.
If the CEA-852 device on the L-INX is used behind a NAT router, the public IP address of the NAT router or firewall must be known. To automatically detect the NAT address leave the Auto-NAT checkmark enabled.
The Multicast Address field allows the user to add the CEA-852 device of the L-INX into a multi-cast group for the CEA-852 IP channel. Enter the channel‘s IP multi-cast address here. Please contact your system administrator on how to obtain a valid multi-cast address.
To learn when it is beneficial to use multi-cast addresses in your channel please refer to the
L-IP User Manual [1].
4.2.8 CEA-709 Router Configuration
This page is only available on L-INX models with the router option (101, 111, 121, 151).
The CEA-709 router configuration page allows configuring the built-in router mode.
Available modes are Configured Router and Smart Switch . The L-INX must be rebooted to let the changes on this page take effect.
The configured router mode is the default setting. Choose this setting if you want to use the
L-INX as a standard configured CEA-709 router that can be configured in a network management tool such as NL-200 or LonMaker.
The Smart Switch mode lets the device act as a self-learning router like the L-Switch. In this configuration the LINX‘s router doesn‘t need to be configured with a network management tool but is completely transparent in the network. Use this operating mode in a plug&play networking environment. The switch mode should only be used in LAN networks. In Smart
Switch mode, this page has two more configuration fields: Subnet/node learning and
Group learning .
Figure 47: CEA-709 Router Configuration Page.
4.2.9 CEA-852 Server Configuration
This page is only available on CEA-709 L-INX models with the router option (101, 111,
121, 151). On this configuration page the configuration server on the LINX-101 can be enabled or disabled. In the drop-down box Config server status select enabled and click
Version 4.0 LOYTEC electronics GmbH
L-INX User Manual 62 LOYTEC on Save Settings to activate the configuration server. Then the configuration server settings
page appears as shown in Figure 48. If the configuration server is enabled the green
configuration server LED labeled CS will be on, otherwise it will be off.
The configuration server port can be changed in the Config server port field. It is recommended to keep the default port setting of 1629. The field Channel name is informational only and can consist of up to 15 characters.
The field Channel members displays the current number of members on the IP-852 channel. The field Channel mode reflects the current channel mode. The L-INX configuration server automatically determines this mode. Depending on if there are any two devices in the channel which use the same IP address but different ports (e.g., multiple
CEA-852 devices behind one NAT router). If all IP addresses are unique, the mode is
Standard , if some are not unique the mode is Extended NAT mode . Please refer to
Section 7.3.2 to learn more about the implications of this mode.
Version 4.0
Figure 48: Configuration server settings.
Enter NTP timer server address and ports in the fields Primary SNTP and Secondary
SNTP . The L-INX will synchronize to NTP time if primary or primary and secondary NTP servers are specified. A list of available timeservers can be found at www.ntp.org
.
The Channel timeout is an IP-852 channel property and indicates how old a packet can be before it is discarded. The channel timeout is set in ms. To disable the channel timeout enter
a value of 0. To select the proper value please consult Section 7.5.2. Setting a channel
timeout other than 0 requires a valid SNTP server entry on the configuration server.
The Auto members option allows members to be automatically added to the channel. If turned on, CEA-852 devices can register on the IP-852 channel without the device being explicitly added on the configuration server. This special feature is useful in combination with the LPA-IP since it can add itself to the configuration server during the debug session.
Non-responding auto members are automatically removed from the channel. This feature is turned off by default and must be explicitly turned on. Use this option with care because new CEA-852 devices can add themselves to the channel without knowledge of the system operator. This could cause a potential security hole.
LOYTEC electronics GmbH
L-INX User Manual 63 LOYTEC
The Roaming members option allows tracking CEA-852 devices when their IP address changes. This feature must be turned on if DHCP is used and the DHCP server can assign different IP addresses to the same device (same Neuron-ID). In combination with Auto-
NAT the LINX‘s router can also be operated behind NAT routers, which change their IP address between connection setups. For more information on this topic refer to Section
7.3.1. The roaming member feature is turned on by default. It is recommended to turn off
this feature if DHCP is not used or if the DHCP server always assigns the same IP address to a given MAC address.
Use the drop-down box MD5 authentication to enable and disable MD5 authentication. If
MD5 authentication is enabled, all devices on the IP-852 channel must have MD5 enabled and must use the same MD5 secret. Note that MD5 authentication cannot be used together with the Echelon‘s i .
LON 1000 since the i .
LON 1000 is not fully compliant with the
CEA-852 authentication method. MD5 can be used with the i .
LON 600. The MD5 secret can be entered over the Web interface. You may enter the 16 bytes as one string or with spaces between each byte, e.g., 00 11 22 33 44 55 66 77 88 99 AA BB CC DD EE FF.
It is recommended, however, to enter the secret locally and not over an Internet connection.
It is best to use a cross-over Ethernet cable connected to the PC.
4.2.10 CEA-852 Channel List
This page is only available on CEA-709 L-INX models with the router option (101, 111,
121, 151). If the configuration server is enabled on the LINX, the CEA-852 device list can
be seen in the CEA-852 channel list menu. An example is given in Figure 45.
The Add Device button is used to add another CEA-852 device to the IP-852 channel. The
Reload button updates the Web page and the Recontact button contacts all devices to update their status. The Execute button executes the option selected in the adjacent dropdown box on the checked members. Each member can be selected for that action in an individual check-box in the Sel column. Actions available are: disable , enable , delete , assign to NAT , and remove from NAT . For more information on the actions on NAT
routers refer to Section 7.3.2.

Further, the description and location can be configured. These configuration items correspond to the properties Description, and Location respectively of the BACnet Device object.
Depending on the selected BACnet/IP mode, applicable fields are enabled and others are grayed-out. Note, that on the LINX-200, the BACnet/IP modes are restricted to Device and
Foreign Device , while the LINX-201 also supports Broadcast Management Device .
For operating the LINX-151,201,211,221 as a BACnet router between BACnet/IP and
MS/TP, the BACnet network numbers for the BACnet/IP and MS/TP ports must be set.
On the settings for BACnet/IP refer to Section 4.2.12. For configuring the MS/TP data link
4.2.12 BACnet/IP Configuration
The BACnet/IP protocol is available on the Ethernet port. To enable BACnet/IP on the device, select the BACnet/IP checkbox on the Ethernet tab of the port configuration page.
Please note that on device models without a router, the BACnet MS/TP protocol on other ports will be disabled (e.g., LINX-200, L-Gate).
The BACnet/IP protocol settings are displayed in the settings box on the right-hand side as
shown in Figure 51. On devices with a router (e.g., LINX-201) the
Network Number of the
BACnet/IP port must be configured to operate the build-in router. If the BACnet/IP network uses a non-default UDP port number other than 47808/0xBAC0, enter this port in the
BACnet/IP port field. Enter ‗0‘ in this field for switching back to the default setting.
Version 4.0
Figure 51: BACnet/IP Configuration.
In the field BACnet/IP mode the operation mode of the device is selected:
Device (Default): In this mode the device operates as a regular BACnet/IP device on the local network without other advanced features.
LOYTEC electronics GmbH
L-INX User Manual 66 LOYTEC
Foreign Device (FD): In this mode, the device registers at an existing BBMD in the
BACnet/IP network as a foreign device. It is used, if the device is located as a single
BACnet/IP device on a remote IP subnet or behind a NAT router. If operated as a foreign device behind a NAT router, port forwarding to the BACnet/IP port (UDP, default port 0xBAC0) and optionally to the Web server and FTP server port (TCP, default port 80 and 21) must be setup in the NAT router. If foreign device is selected, the following, additional settings must be made: o FD BBMD IP address and FD BBMD port : IP address and port of the remote BBMD the device registers at as a foreign device. o
FD re-registration : A foreign device must periodically re-register at a
BBMD. Here you can setup the corresponding interval. The default is 1800 seconds. o FD retry timeout and FD retries : Here you can specify the behavior, if registration does not work instantly. These values should be left at default:
30000ms / 3 retries.
Broadcast Management Device (BBMD): This option is available on the LINX-201
only. Same as ‗Device‘ but the BBMD function is enabled (see Section 4.2.14). For
BBMD-only function, MS/TP can also be disabled (see Section 4.2.13).
4.2.13 MS/TP Configuration
The BACnet MS/TP protocol can be enabled on the device‘s port Port2 if available. To enable it, click the BACnet MS/TP
radio button as shown in Figure 52. Note, that
depending on the device model, other protocols on the same port will be disabled in this case. On a BACnet L-INX without a BACnet router BACnet MS/TP port is not enabled by default. On a BACnet L-INX with a BACnet router the MS/TP port is enabled by default.
Figure 52: MS/TP Configuration.
The MS/TP protocol settings are displayed in the settings box on the right-hand side as
shown in Figure 52. Mandatory settings are the
MS/TP node number and the MS/TP baud rate. The MS/TP node number determines the physical address of the device on the
MS/TP channel and must be in the range from ‗0‘ to the number configured with the
MS/TP max master configuration option. It must be unique within the MS/TP channel.
The Baud rate on the MS/TP channel can be set to 9600, 19200, 38400, and 76800 Baud. It is strongly recommended to leave the MS/TP max info frames and the MS/TP max master configuration options at their default settings.
On a L-INX with a BACnet router, the Network Number of the MS/TP port must be configured to operate the build-in router. On the LINX-201 the MS/TP port can be disabled independently of the BACnet/IP port.
4.2.14 BACnet BDT (Broadcast Distribution Table)
The BBMD function is only available on L-INX models with the BACnet router option
(151, 201, 211, 221). The BBMD function is needed when a BACnet/IP network spans over several IP subnets separated by IP routers. If the device is configured as a BBMD, i.e. the
Version 4.0 LOYTEC electronics GmbH

The data point has no valid value.
The data point has a value but it is not reflected on the network due to a configuration error (not commissioned, no binding, no client mapping, etc.)
The data point has a value but it is not reflected on the network due to a communication error (e.g., the peer node is not online).
The data point is in normal operation. The value of it, however, is qualified as unreliable because a connected data point is offline. For an output data point it means that the value was fed from a connection, where the source is offline. For an input data point it means that the connected output data point could not send the value to the network.
The data point is in normal operation. The value of it, however, is qualified unreliable because the value is an out-of-range value for the connected data point. The value is limited to the supported range.
The data point is in normal operation. The value of the data point or a connected data point has been tagged as unreliable over the network. This is the case when the BACnet reliability has been written.
The data point is mapped to a port, which is not configured (e.g., the port is disabled).
The data point is inactive and the line is grayed-out. Values can be written but no network communication is triggered. This can be the case, if a data point is not used in the configuration or it is connected to a BACnet server object, which is not present on the device.

To entirely disable a scheduler de-select the Enable Schedule check box.
Schedules are defined per day. On the left-hand side, the weekdays Monday through
Sunday can be selected, or exception days from the calendar, e.g., Holidays. Once a day is selected, the times and values can be defined in the daily planner on the right-hand side. In
the example shown in Figure 58, on Monday the value
day is scheduled at 8:00am . The same principle applies to exception days . Exception days override the settings of the normal weekday. Put a check mark on those exception days from the calendar, which shall be used in the schedule. To edit the date ranges of exception days click on the links to the used calendars, e.g., ‗calendar‘ or ‗Scheduler_1‘. The ‗Scheduler_1‘ is a calendar, which is embedded into the schedule and not accessible by other schedulers. For more information
on how to set up schedules and calendars refer to Section 6.12.
To define actual values for the names such as day click on the tab Presets as shown in
Figure 59. To define a new value, click on the button

Active alarms are highlighted red. Inactive alarms which have not been acknowledged are rendered in green. Alarms that can be acknowledged have an Ack button. Press on the Ack button to acknowledge the alarm. Depending on the technology, this and older alarm records will be acknowledged. Acknowledged, active alarms are rendered in red. Click on
Reload to refresh your alarm list.
Inactive alarms that have been acknowledged disappear from the list. To record historical
information about those alarms, the alarm log must be used. See Section 4.3.9 for the alarm
log Web interface.
4.2.21 IEC61131 Configuration
On the IEC61131 configuration page the user can download an IEC61131 program as well
as controlling the behavior of the IO driver, see Figure 63.
After downloading the IEC61131 program rebooting the L-INX is necessary in order to load and start the new IEC61131 program. After resetting the device check the PLC LED for a successfully started program.
Important! Downloading a new IEC61131 may result in the need for a new data point configuration.
Hence, take care about the requirements of the downloaded program and in case of a different set of IEC61131 variables use the L-INX configuration tool to adapt the data point configuration.
The data exchange of the IEC61131 program can be disabled by disabling the IO driver. As a result the IEC61131 program is not able to receive or send update from/to the appropriate data points. Hence, for debugging purpose, the data point values can be manipulated regardless of the data set from the IEC61131 program.
Version 4.0 LOYTEC electronics GmbH
L-INX User Manual 75 LOYTEC
The information about the running program is also displayed. The IEC61131 program can be removed from the device by clicking the Remove button. The device needs to reboot after this action.

4.3.4 Enhanced Communications Test
The Enhanced Communications Test allows testing the CEA-852 communication path between the CEA-852 device on the L-INX and other CEA-852 devices as well as the configuration server. The test thoroughly diagnoses the paths between individual members of the IP channel and the configuration server in each direction. Port-forwarding problems are recognized. For older devices or devices by other manufacturers, which do not support the enhanced test features, the test passes as soon as a device is reachable, but adds a
comment, that the return path could not be tested. A typical output is shown in Figure 67.
Version 4.0 LOYTEC electronics GmbH
L-INX User Manual 78 LOYTEC
Figure 67: Enhanced Communication Test Output.
The Round Trip Time (RTT) is measured as the time a packet sent to the peer device needs to be routed back to the LINX-10X. It is a measure for general network delay. If the test to a specific member fails, a text is displayed to describe the possible source of the problem.
The reasons for failure are summarized in Table 10.
Text displayed (Web icon) Meaning
OK, Return path not tested (green checkmark)
Not reachable/not supported
(red exclamation)
Local NAT config. Error
(red exclamation)
Peer not reachable
(red exclamation)
Displayed for a device which is reachable but which does not support the feature to test the return path (device sending to this CEA-852 device).
Therefore a potential NAT router configuration error cannot be detected. If the tested device is an L-IP, it is recommended to upgrade this L-IP to 3.0 or higher.
This is displayed for the CS if it is not reachable or the CS does not support this test. To remove this uncertainty it is recommended to upgrade the L-IP to
3.0 or higher.
This is displayed if the CEA-852 device of the LINX-10X is located behind a
NAT router or firewall, and the port-forwarding in the NAT-Router (usually
1628) or the filter table of the firewall is incorrect.
Displayed for a device, if it is not reachable. No RTT is displayed. The device is either not online, not connected to the network, has no IP address, or is not reachable behind its NAT router. Execute this test on the suspicious device to determine any NAT configuration problem.
Table 10: Possible Communication Problems.
4.3.5 CEA-709 Statistics
The CEA-709 statistics page displays statistics data of the CEA-709 port on the device as
shown in Figure 68. This data can be used to troubleshoot networking problems. To update
the data, click on the button Update CEA-709 statistics .

4.3.6 OPC Server Statistics Page
The OPC server statistics page shows statistics data, which contains information on currently and previously connected clients. An example list of OPC clients is shown in
Update OPC statistics button retrieves the current statistics.
The Summary table on the top of the page displays the number of currently connected clients. These clients occupy TCP connections. The next line specifies the total number of accepted client connections since the device is running. The figure for rejected connections can be used to detect situations, where too many clients try connecting at the same time.
Version 4.0
Figure 69: OPC Server Statistics Page.
LOYTEC electronics GmbH
L-INX User Manual 80 LOYTEC
The Connection Details list shows more information on the history of client connections.
The green lines at the top denote currently active connections. Active connections have an idle time figure specified in seconds. The following lines in black represent a history of the most recent connections. Inactive connections read ―n/a‖ in the
Idle column.
All lines contain client information, which specifies the client IP address and port of the connected client. The Srvc column specifies the type of Web service (Web, DA, and DL).
The Agent column contains information on the HTTP agent of the client, and the Last
Action column contains information on the last known Web service SOAP action the client has requested.
4.3.7 BACnet MS/TP Statistics
The BACnet MS/TP statistics page is only available, when the MS/TP data link layer is
enabled (see Section 4.2.13) and supported by the L-INX model. An example is shown in
Figure 70. The separated part on the top of the table contains the most important statistics
data.
The MS/TP token status reports the current token passing state. In state OK , the token is circulating between the masters. This is the normal state, when multiple masters are on the
MS/TP network. The state SOLE MASTER is the normal state when the device is the only master on the network. If there are multiple masters on the network, this state is a hint to a broken cable. In state TOKEN LOST , the token is currently not circulating.
The counter MS/TP lost tokens is an indicator for communication problems on the
MST/TP network. If it increases, there is a cabling, ground, or termination problem. The counters Rcv OK and Send OK reflect the number of successfully received or transmitted
MS/TP frames. Check these counters to verify that communication is flowing on the MS/TP segment.
