Overview

This chapter introduces Echelon’s MPR-50 Multi-Port Router.

MPR-50 Multi-Port Router User's Guide 1

Introduction

Echelon’s MPR-50 Multi-Port Router performs LonTalk® (ANSI/CEA-709.1 standard) routing between five LonTalk channels: one TP/XF-1250 channel and four TP/FT-10 channels. The MPR-50 may be used as a 2-way, 3-way, or 4-way TP/FT-10–to–TP/FT-10 router, or in any combination with the TP/XF-1250 router.

The MPR-50 helps reduce the number of routing devices in multi-channel networks, reducing both installation cost and time. The MPR-50 provides the highest possible messaging performance: all four of the TP/FT-10 channels operate at saturation, the maximum possible operating rate. The MPR-50 includes a flexible power supply, a

Hardware and Software

This chapter provides a description of the MPR-50 Multi-Port Router hardware, including enclosure construction, mounting instructions, explanation of indicators and connectors, and wiring guidelines. In addition, the Multi-Port Router CD contents and installation instructions are described in this chapter.

MPR-50 Multi-Port Router User's Guide 3

Mechanical Description

The MPR-50 is 35mm DIN rail compatible, 9 TE wide, and conforms to EN 50 022. The figure below presents the front view of the MPR-50 Multi-Port Router. The face of the MPR-50 includes a network diagram that shows how the five routers and the Monitor are externally and internally connected.

Mounting and Connecting

The MPR-50 Multi-Port Router enclosure is designed for mounting on a DIN rail or wall/panel. A spring-loaded DIN rail lock securely grabs the DIN rail onto which the enclosure is mounted. Tabs in the DIN rail area present a pressure fit on the DIN rail, which prevents the MPR-50 from sliding. The DIN rail lock must be activated to either remove the MPR-50 from a DIN rail or to slide the router along the DIN rail. To release the enclosure from the DIN rail, insert a flathead screwdriver into the DIN rail locking tab and gently pull the tab downwards (away from the enclosure). Figure 2.2 shows the location of the DIN rail-locking tab.

Wiring Screw Terminals

4 MPR-50 Multi-Port Router Hardware and Software

Four key hole slots in the rear of the enclosure are provided for wall/panel mounting the router. The key hole slots on each side of the DIN rail allow mounting normally or upside-down. The top of the MPR-50 includes two scored alignment guides for positioning the screws and for aligning the MPR-50 with the screws during mounting.

Use the following steps to mount the router.

1. Insert two 6-32 flat-head screws into the surface upon which the MPR-50 is to be mounted. Mounting dimensions are shown in the following drawing, in millimeters.

3. Be sure the heads of screws are protruding slightly from the mounting surface.

4. Slide the MPR-50 onto the screws. It may be necessary to adjust the screws into or out of the wall slightly to assure a secure mounting.

Screw Terminal Connectors

The screw terminals for connecting power and network wires are located on the bottom edge of the enclosure. The screw terminals accept 0.34–4.0 mm 12AWG) gauge wire. The optimum tightening torque for the screw terminals is

0.75mm (6 lbs. in.) maximum. The ideal flathead screwdriver tip width for use

with the screw terminal connectors is 3mm (0.12”). Wires should be stripped to a length of 7mm (0.28”). A soldering iron may be used to tin the stripped lengths of any stranded wires to prevent fraying and inadvertent contact with adjacent terminals, although this is not required.

Applying Power to the MPR-50 Multi-Port Router

Connect earth ground, if available, to terminal 3. Then connect 9–28VAC (40–70Hz)

or 9–35VDC power to terminals 1 and 2—the power terminals are polarity-

insensitive so the polarity of the DC input is unimportant. The green Power LED will illuminate to indicate the unit is powered and the Status LEDs will begin operating within seconds.

Attaching the Router to a LONWORKS Network

Connect the screw terminals marked Router 1 through Router 5 to the desired channels. Router 1 is for the TP/XF-1250 channel, while Routers 2–5 are for the TP/FT-10 channels. TP/XF-1250 and TP/FT-10 channel wiring is polarityinsensitive, and the TP/FT-10 connections are link power compatible. Any router that is not going to be used may be left unconnected.

Service Buttons

The MPR-50 Multi-Port Router has six service buttons: one for the Monitor and one for each of the routers. To reset the MPR-50 Multi-Port Router to factory defaults, hold the Monitor service button down for 10 seconds.

Note that service pin messages are broadcast onto any attached channels when the unit is put into factory default state. Some tools that listen for service pin messages and perform automatic configuration may recognize the MPR-50 and begin configuring it, potentially unexpectedly.

Channel Connectors

The MPR-50 front panel includes a separate 3.5mm (1/8”) mono phone jack for each of the five external channels. The jack is compatible with the connector used on the

Connecting to the Network

This chapter demonstrates how to install the MPR-50 MultiPort Router on a network.

MPR-50 Multi-Port Router User's Guide 11

Installing the MPR-50 on a Network

Once the MPR-50 is physically attached to a network and powered-up, it must be logically installed on the network. The MPR-50 is by default unconfigured and will not route messages in this state. The MPR-50 can either be put into repeater mode (which requires no network management tools), or it can be commissioned using standard network management tools such as the LonMaker tool.

The Monitor within the MPR-50 only needs to be commissioned to interact with it over the network. If the Monitor will not be accessed over the network, it does not need to be commissioned.

Repeater Mode

To use the MPR-50 on a network without using network management tools, it must be put into the repeater mode. Repeater mode is useful for the following:

• Self-installed networks where physical length of the network or node density

per-channel requires the use of a router

• Replacing free topology physical-layer repeaters, as physical-layer repeaters

are susceptible to noise which can halt traffic not just on the noisy channel, but on the entire network

• Networks that have low traffic density and protocol routing is not required.

When in the repeater mode, the MPR-50 does not segregate traffic and may not be appropriate for larger networks, or networks with traffic levels that in aggregate approach saturation for the slowest channel.

To put the MPR-50 into repeater mode, hold down the Monitor Service button continuously for 20 seconds. The Monitor Status LED will slowly flash green after repeater mode is entered. To take the MPR-50 out of repeater mode, either hold down the Monitor Service button continuously for 10 seconds (this will set the MPR50 to the factory default state), or commission Routers 1–5 management tool (in this case it is not repeater mode).

ONMARK resource files

Commissioning with the LonMaker Integration Tool

The LonMaker tool is an easy-to-use integration tool that supports both routers and application devices. According to the protocol specification, devices on separate channels cannot communicate unless the channels are connected by a router. This section describes how to create a router in a LonMaker network design.

These instructions assume the use of LonMaker 3.1. Newer versions of the LonMaker tool may operate differently; in particular, there may be fewer dialogs presented to the user during router definition and commissioning.

Routers, like devices, are created in two steps: definition and commissioning.

Defining an MPR-50 Router

To define the MPR-50, follow these steps:

1. If the Multi-Port Router Shapes stencil is not open, open it from File->Stencils.

2. Drag a MPR-50 master shape from the Multi-Port Router Shapes stencil

onto the drawing.

3. The Channel Definition dialog appears. Most users will want to click OK

repeatedly thus accepting all of the defaults presented. The most common exception to accepting the defaults is choosing to connect to a pre-existing channel. Accept all other default values in this case. The routers are defined in reverse order, from Router 5 to Router 1.

Note: When defining multiple MPR-50 routers within a drawing, make certain that the Internal Channel of each MPR-50 is defined as a separate channel.

4. To monitor and control the status and logging objects on the Monitor, drag the

MPR-50 Node Object and MPR-50 Channel Monitor objects onto the drawing. Note that there is one Node Object and five Channel Monitor objects. Drag onto the drawing Channel Monitor objects that correspond to the channels you are using with the MPR-50.

MPR-50 Multi-Port Router User's Guide 13

Moving a LonMaker Shape

The MPR-50 shape can be moved within a LonMaker drawing; the MPR-50 shape moves as a unit that includes the five router shapes, the Monitor shape, and the internal channel.

• To move the MPR-50 shape within a subsystem (page), drag the shape to its

desired location.

• To move an individual router to another subsystem, right-click the shape to move

and then click Change Subsystem on the shortcut menu.

Note: You cannot move LonMaker shapes using Visio's cut and paste commands.

Commissioning an MPR-50 Router

1. Right-click the shape of the router that you have connectivity to from your

LonMaker tool, and then click Commission. The Commission Device Wizard appears. Note that you may have connectivity to any of the five routers—it is not necessarily Router 1 as shown below.

2. Select whether the router application will be online or offline upon

commissioning. The router can forward packets between its channels only when it is online. Most end-users will want to choose online.

14 Connecting to the Network

3. Click Next. The Device Identification Method window appears.

4. Select a method for obtaining the Neuron

ID of the router. You can choose to either press the service pin of the router when prompted or directly enter its Neuron ID.

5. Click Finish. The Press Service Pin window appears.

6. Press the service pin of the router. The LonMaker tool commissions the router.

7. Click the Monitor shape and hold down SHIFT. Click the router shapes for all of

the other routers you want to commission. Right click, and then click Commission. The Commission Device Wizard appears.

MPR-50 Multi-Port Router User's Guide 15

8. Set the State, Source of CP Values and Device Specific CPs options as

appropriate. See the LonMaker User’s Guide for an explanation of the effects of the various options.

9. Click Next. The Commission Device Wizard appears.

MPR-50 Monitor

This chapter describes the interfaces and functionality of the MPR-50’s Monitor.

MPR-50 Multi-Port Router User's Guide 21

Introduction

The MPR-50’s Monitor observes and reports on the health of Routers 1–5 through

Status LEDs and through the network. The Monitor can be commissioned by a network management tool and operates independently from the MPR-50’s five routers.

The Monitor is a L In addition to the Node Object, it contains one Channel Monitor functional block

each for Routers 1–5.

For the sake of efficiency, bit arrays, network variable arrays, and configuration property arrays are used. It is important to understand that the L file and LonMaker tool indices start at zero while, for ease-of-use, the Routers are numbered one through five on the enclosure, as well as on the LonMaker shapes. The following table shows the indices to these arrays:

Array Index

0 Router 1 – TP/XF-1250 Router 1 (1250) and Channel 1 (1250) 1 Router 2 – TP/FT-10 Router 2 (FT) and Channel 2 (FT) 2 Router 3 – TP/FT-10 Router 3 (FT) and Channel 3 (FT) 3 Router 4 – TP/FT-10 Router 4 (FT) and Channel 4 (FT) 4 Router 5 – TP/FT-10 Router 5 (FT) and Channel 5 (FT)

Self-Installation

LonMaker Stencil

The Monitor self-installs and does not need to be installed by a network management tool in order to provide status via the front panel LEDs. To obtain status from the Monitor remotely, it should be installed by a network management tool. The Monitor intelligently manages its own installation state so that the user does not need to manage it.

Service Button

Momentarily pressing any of the Service buttons causes the associated Monitor or router to transmit a service pin message (a router transmits two service pin messages—one onto the MPR-50’s internal channel and one onto its external channel). Since the Monitor is attached to the internal channel, a service pin message from the Monitor will be routed onto a particular external channel only if the associated router that connects the internal channel to the external channel is configured to route messages.

22 MPR-50 Monitor

To reset the MPR-50 to factory defaults, hold the Monitor Service button down for 10 seconds. Release the Service button as soon as the Status LEDs change after 10 seconds have elapsed. The Monitor will self-install and Routers 1–5 that they are unconfigured.

Note that when resetting the MPR-50 to factory defaults, service pin messages are broadcast onto any attached channels. Some tools that listen for service pin messages and perform automatic configuration may recognize the MPR-50 and begin configuring it, potentially unexpectedly.

To put the MPR-50 into repeater mode, hold down the Monitor Service button continuously for 20 seconds. The Monitor Status LED will slowly flash green after repeater mode is entered. To take the MPR-50 out of repeater mode either hold down the Monitor Service button continuously for 10 seconds (this will set the MPR50 to the factory default state), or commission Routers 1–5 management tool (in this case it is not repeater mode).

Two configuration properties on the Monitor’s Node Object functional block (UCPTfactoryDefaultsEnable and UCPTrepeaterModeEnable) determine whether the Monitor's Service button can be used to reset the MPR-50 to factory defaults, or put it into repeater mode. By default these two configuration properties are set to True. However, one or both of these configuration properties can be set to False with a network management tool in order to prevent tampering with the configuration of the MPR-50 via access to the front panel.

Wink Request

A network tool may send a wink message to the MPR-50 to help physically identify it. When a wink request is received, the Monitor will illuminate the Router 1–5 Status LEDs in a distinctive sequence.

A wink request is ignored if a wink sequence is currently in progress.

When diagnosing a network problem, it may be useful to use this network variable to clear all of the router statistics and error log after corrective actions have been taken, so that one can verify whether or not the actions were effective. The Status LEDs on the front panel, if they indicated error conditions, will also revert to their normal status indications, until another error occurs.

It is not necessary to set the network variable to OFF. It automatically sets itself to OFF once the ON state is detected. The value field of this network variable is ignored by the Node Object; however, the network tool should send valid values.

The default state is OFF. The Status LED behavior is described

in Chapter 2, MPR-50 Multi-Port Router Hardware and Software. The error log is described in the Error Log section, later in this chapter.

Elapsed time since power-up or last reset. Normally used to compute at what time in the past events logged in the error log occurred. The MPR-50 does not have a real-time clock, which means this variable is subject to accuracy errors particularly over long periods of time.

Used to transmit alarm data for each functional block on the device whenever an alarm occurs or is cleared, and upon request. For more information, see the Alarms section, later in this chapter.

If set to True (the default), an end-user can use the Monitor Service button to put the MPR-50 into repeater mode. To prevent tampering with the configuration of the MPR-50 from the front panel, disable this feature by setting the configuration property to False.

Error Log

Certain network variables that are part of the Channel Monitor functional blocks are alarmed, and the Monitor maintains an error log of any alarm conditions. The log is circular, the entries are in the SNVT_alarm_2 format, and it contains up to 50 of the latest alarms. Think of this error log as the latest 50 values that have been output on the Node Object's nvoAlarm2 output. The error log is not retained across power cycles or resets.

A network management tool can read this error log using standard L memory read/write commands, and use the error log contents to aid in debugging network problems. The network management tool uses the nvoFileDirectory network variable to find the location of the error log. LNS based tools can use the available LNS FileTransfer method to transfer the log file. For instance, when using LonMaker Turbo Edition, choose LonWorks FTP… from the LonMaker menu. When not using an LNS based tool, see the Node Object Functional Profile and the

ONMARK Application Layer Interoperability Guidelines on the LONMARK Web site

L for details about how to read the log file.

The index of the log file in the Monitor is 3. The format of the error log is as follows:

ONMARK direct

To compute the time at which an alarm in the error log occurred, first compute the alarm time by using the alarm_time and milliseconds fields from a particular error log record. The record format is SNVT_alarm_2. Then read the nvoElapsedTime network variable. Using the difference, subtract that time from the local time of day. Don't forget to factor in daylight savings time, if applicable.

Since direct memory commands are used to read the log, it is possible that the Monitor will be updating the log while a network management tool is reading it. In order to ensure that reads are consistent, read the error log only after all of the Channel Monitor functional blocks are temporarily disabled.

Network Variables

Each of the five Channel Monitor functional blocks collects information about the number of errors and number of messages on the associated externally-connected channel. This information is used to update the Status LEDs described in LED Legends in Chapter 2, and this information is also available on the network through the following network variables:

Configuration Properties

Each of the five Channel Monitor functional blocks implements the following configuration properties. The alarm configuration properties are described separately in the next section, Alarms.

Configuration Property Description

SCPTholdTime

SCPTneuronId

The amount of time (in tenths of seconds) that a router's Status LED flashes green after detecting activity on its external channel.

An array that contains the two Neuron IDs of the router, with the first Neuron ID in the array being on the internal channel of the MPR-50, and the second Neuron ID in the array being on the external channel. This configuration property is useful for network management tools and plug-ins to be able to automatically install all of the routers in the MPR-50 by reading this configuration property and then being able to know which router is connected to which external channel.

28 MPR-50 Monitor

UCPTinterval

UCPTpacketBytesAverage

UCPTpacketsPerSecondMax

This configuration property defines the interval over which statistics are collected. Its type is SNVT_elapsed_tm, with the default being one minute. The maximum interval supported is 65,535 seconds (over 18 hours). A minimum interval of 5 seconds is enforced, which means that if this configuration property is set to a value below 5 seconds, the statistics interval will be 5 seconds. This is a shared configuration property that applies to all of the Channel Monitor functional blocks.

To calculate bandwidth utilization, the Monitor uses an approximate value for the average packet size. The average packet size defaults to 15 bytes, but can be configured to whatever your average message size is.

The bandwidth utilization calculation is made relative to a fixed model of the maximum channel capacity of the TP/FT-10 and TP/XF-1250 channels. The default is 0 for all channels and should not be changed.

Alarms

The Monitor implements LONMARK alarms for several network variables in the Channel Monitor functional blocks. The alarmed network variables and their default alarm limits are listed below. These alarm limits may be modified with a network management tool.

Note: The programmatic Network Variable name appears first. The LonMaker Channel Monitor's Network Variable shape name is located under it, in parentheses.

High Hysteresis

Alarm conditions are reported on the nvoAlarm2 output on the Node Object. This output is of type SNVT_alarm_2 and contains a string with the current alarm source, the error type, and the percentage value. The following alarm source strings are used (where <n> is for router (and channel) and xx is either a whole number like 57 or a real number like 49.5.):

• Ch<n>: CRC errors (xx%)

• Ch<n>: Missed (xx%)

MPR-50 Multi-Port Router User's Guide 29

• Ch<n>: Bandwidth (xx%)

In the L for each of the low and high limits. The MPR-50 implements a single limit according to the following rules:

1. If the alarm type was not AL_HIGH_LMT_ALM_1 and the value is now greater

2. If the alarm type was AL_HIGH_LMT_ALM_1 and the value drops below

3. If the alarm type was not AL_LOW_LMT_ALM_1 and the value is now less than

4. If the alarm type was AL_LOW_LMT_ALM_1 and the value rises above

The nvoIvalCrcErr and nvoIvalMissed variables have a high alarm limit (SCPThighLimit1) and do not have a low alarm limit. A hysteresis value (SCPThystHigh1) is used to prevent oscillation of the alarm condition when it is near the high alarm limit value. The high alarm is enabled by default via the SCPThighLimit1Enable property.

ONMARK guidelines, the possibility exists for two limit levels (levels 1 and 2)

than SCPThighLimit1, then the alarm type becomes AL_HIGH_LMT_ALM_1.

SCPThighLimit1 minus SCPThystHigh1, then the alarm type becomes AL_HIGH_LMT_CLR_1. For high limit alarms, the hysteresis value is used only to

subtract from the limit value.

SCPTlowLimit1, then the alarm type becomes AL_LOW_LMT_ALM_1.

SCPTlowLimit1 plus SCPThystLow1, then the alarm type becomes AL_LOW_LMT_CLR_1. For low limit alarms, the hysteresis value is used only to

add to the limit value.

The nvoIvalBandUtl variable has both a high alarm limit (SCPThighLimit1) and a low alarm limit (SCPTlowLimit1). The high alarm is enabled by default via the SCPThighLimit1Enable property, and the low alarm limit is disabled by default via the SCPTlowLimit1Enable property. The low alarm limit can be useful to detect that, for instance, a certain level of background heartbeat traffic expected on a channel has slowed or stopped—which indicates a power, channel wiring, or other problem. If the low alarm limit is enabled, also set the SCPTlowLimit1 property to a non-zero value that is slightly below the expected level of background heartbeat traffic. Hysteresis values (SCPThystHigh1 and SCPThystLow1 as appropriate) are used to prevent oscillation of the alarm condition when it is near the alarm limit value.

Symptom Troubleshooting Solutions

The Power LED is not on continuously.

A network tool does not receive a service pin message when the Monitor’s Service button is pressed.

The network tool returns error messages when attempting to install Routers 1–5 and the Monitor in a single operation.

• Verify that the input voltage measured

at the MPR-50 power input connector is within limits.

• Verify that the input power is connected

to terminals 1 and 2.

• Remove the earth ground connection

temporarily if it is connected.

• Verify that Service pin messages from

other devices can be received.

• Verify that the router inside the MPR-50,

in between the Monitor and the network tool, has been commissioned properly by the network tool or is in repeater mode.

• Verify that the network wiring is

functional by pressing the Service button on any intervening routers, and on the router inside the MPR-50, in between the Monitor and the network tool.

• Verify that the proper transceiver types

are connected to a particular channel. For instance, verify that a TP/FT-10 channel is not – TP/XF-1250 port of the MPR-50, and that a TP/XF-1250 channel is not connected to Routers 2-5.

• Verify that the network channels are

properly terminated with either a single or double termination, as required.

• If the configuration of Routers 1–5 is in

doubt, put it into repeater mode. Then press the Service button on the Monitor.

• First commission only the router nearest

to the network tool. Then commission the other routers and the Monitor at the same time.

Buffer Management Utility

This appendix explains how to use the buffer management utility for the MPR-50 Multi-Port Router.

MPR-50 Multi-Port Router User's Guide 35

Buffer Management Utility

The MPR-50 Buffer Management utility is a stand-alone Windows program that allows you to:

• Change the MPR-50 Network buffer sizes.

• Fix the buffer settings if they become corrupted (for example, if they are set

to an invalid number).

Figure 1 shows the main window for the utility. This program provides four common buffer sizes for the MPR routers. If you need to use a different buffer size than what is provided, see

Changing the Utility’s Buffer Sizes.

36 Appendix A – Buffer Management Utility

Installing and Running the MPR Buffer Management Utility

To install the MPR-50 Buffer Management utility, unzip the files from the supplied ZIP file into the LONWORKS bin directory (usually, C:\LonWorks\bin). This step creates a new directory with four files.

To run the MPR-50 Buffer Management utility, double click the icon for the “MPR50Tool.exe” file.

This program requires the following Windows dynamic link library (DLL) files to be present on the Windows system:

• LDV32.DLL – for the LDV32 interface

• MFC42.DLL – for the Microsoft Foundation Classes

This program supports the following Network Interfaces:

• Supported: USB U10 and RNI (e.g., i.LON

• Not Supported: IP-852 Network Interfaces.

10 and i.LON 100).

Using the MPR Program

To check the MPR-50 buffer sizes:

1. Connect the network interface to any of the MPR routers (e.g., Router 2). a. Router 1 is for a TP/XF-1250 channel and Routers 2 – 5 are for TP/FT-10

channels.

2. Select the Network Interface and click Open. a. Click Close to close the Network Interface.

Checking the Current Buffer Sizes

To check the MPR-50 buffer sizes:

1. Make sure the Buffer Recover Mode button is off (i.e., grey background).

2. Click the Routers Found Button to clear the list of registered routers.

3. Press each MPR router service pin. The buffers sizes will be displayed in the Log

Box.

Using Buffer Configure

To configure the MPR-50 buffers, you first need to configure the MPR-50 for repeater mode. If you are unable to configure the MPR-50, or it is not working, then the router buffer settings might be corrupted. To fix them, use the Buffer Recover Mode on the routers before changing the buffer sizes to the desired values; see

Buffer Recover Mode Note: While the Buffer Recover Mode is enabled (the button is orange), when you press a Service Pin on the MPR-50, the utility tries to recover the buffers for that router and sets the buffer size to 114 bytes.

To change the MPR-50 buffer sizes:

1. Decommission all the routers in the MPR-50 if they have been commissioned

before. If the MPR-50 has not been commissioned or if all the MPR-50’s status

To decommission the routers, perform either of the following steps:

a. Use your Network Integration Tool (such as the LonMaker

LonMaker tool, right-click the router shape and select decommission.

b. Press the Service Pin button on each router for at least 20 seconds until the

Status LED flashes orange.

2. Connect your Network Interface to any of the MPR-50’s routers.

3. Place the MPR-50 in Repeater mode by pressing the Monitor Service Pin button

for 30-40 seconds. The MPR is in repeater mode when all the LEDs flash green.

4. Start the MPR-50 Buffer Management utility.

5. Select the Network Interface device from dropdown list in the Network Interface

area of the MPR-50 Buffer Management utility main window, and click Open.

6. Select the buffer size that you want from the Buffer Configurations area of the

MPR-50 Buffer Management utility main window.

7. Ensure that the Buffer Recovery Mode is off and that the button’s background

is grey and not orange (or yellow). When the button is grey, you are in buffer configuration mode.

8. Press the Service Pin button on all of the MPR-50’s routers.

As you press each of the Service Pins, notice that the number displayed on the Routers Found button of the MPR-50 Buffer Management utility main window is incremented. When you see “*5*” on the Routers Found button, the utility has received all five of the MPR-50 routers’ Service Pin messages. You must press the Service Pin for all of the MPR-50’s routers before the utility can configure their buffers.

If the utility does not recognize all of the routers’ Service Pin messages, then the MPR-50 is likely not in Repeater Mode (see step

3).

You can click the Routers Found button to clear the list of registered routers.

9. Click the Buffer Configure button on the MPR-50 Buffer Management utility

main window to change the buffer sizes.

10. The log area of the MPR-50 Buffer Management utility main window shows

“Buffer configuration complete” when the buffers have been successfully modified.

38 Appendix A – Buffer Management Utility

Using Buffer Recover Mode

You can use the MPR-50 Buffer Management utility’s buffer recovery mode to recover router nodes that have had invalid buffer configurations programmed into them. Without the MPR-50 Buffer Management utility, buffer recovery can be difficult. For example, some configurations result in a router that is only capable of receiving a few network packets before it enters a state in which it can no longer receive messages. In these cases, it might be necessary to reset (power cycle) the router before attempting recovery. As a further complication, the Monitor Node periodically tries to communicate with these router nodes, which uses packet buffers if the router node is configured incorrectly. When you click the Buffer Recover Mode button, the MPR-50 Buffer Management utility enters the buffer recovery mode; if you click this button again, the utility returns to buffer configuration mode. While the utility is in buffer recovery mode, any Service Pin message captured by the utility causes it to perform the following steps:

1. It checks the Program ID to ensure that the message came from a router.

2. It uses the Neuron

router node using the un-ack’d service. The utility uses this service because the node might not be able to generate a response. The router is also reset as a result of the buffer configuration message.

3. After a small delay, the utility uses the same Neuron ID to send a buffer

configuration message to the far router node using the un-ack’d service. The router is reset as a result.

4. After another small delay, the utility reads the router’s far side buffer

configuration and confirms it.

If this process is successful, you should proceed with the next router using the connectivity that you now have with the recovered router. If it is impossible to recover the other routers using the internal channel path, you may have to approach the routers from each of their external channel interfaces.

Note: A single “safe” default buffer configuration is used for all recovery operations (the same one used for the default configuration of the FT10 nodes). Normally, the internal node configuration is different from the external node configuration, and the TP1250 configuration is quite large. To correct for this difference, after the recovery process is complete, you should re-configure all five routers using the normal buffer configuration mode.

Fixing the MPR-50 buffers because of a corrupted buffer can take several attempts to fix all five routers. To fix the MPR-50 buffer sizes:

1. Decommission all the routers in the MPR-50 if they have been commissioned

before. If the MPR-50 has not been commissioned, proceed to step decommission the routers, perform either of the following steps:

Changing the Utility’s Buffer Sizes

The utility uses a text file that presents up to four separate “Buffer Configurations”. This is a comma-separated value (CSV) file that contains an informational header plus various buffer configuration fields. The file name is “buffconfig.csv”, and you can edit it with a text editor or a spreadsheet application (such as Microsoft Excel). This file must exist in the same folder as the utility’s executable file. Also provided is an alternative CSV file that shows how to support 255 byte buffers (see the “Alternate CSV” sub-directory).

Table 1 shows an example of the file layout.

The “NodeID” field must contain one of the following values:

• EXTFT10

• INTDIFF

• EXTTP12

The “Name” field is used to create one of the four unique buffer configurations that appear in the “Buffer Configurations” area of the utility.

The rest of the fields refer to standard Neuron buffer configurations values. The order of the rows in the file are only important in that the first three entries are used to set the default values. However, the order of the columns are important because they are always assigned in the order that matches the descriptors listed in the table (the program doesn’t use these descriptors; they are purely informative for the CSV file).

For each unique configuration “Name” value, there should be 3 entries, one for each NodeID. The utility checks all values against the acceptable buffer configuration

MPR-50 Multi-Port Router User's Guide 41

values, and rejects any that are out of range, including Network buffer sizes that aren’t consistent within a specific configuration. If you attempt to use a buffer configuration that exceeds the available RAM for the particular NodeID type, the utility displays an error and the configuration will not proceed. The utility communicates with the router nodes using Neuron ID addressing on the zero-length domain. As each router is configured, the utility resets it before proceeding to the next router.
