9 ConfigWiz Addendum Client Configuration The following is a Description of the configuration using ConfigWiz. DNP3.0 is a multi-function, multi-layer protocol that involves complex client/server and inter-layer interactions. The user must possess a thorough understanding of the protocol features and their application prior to proceeding with the client configuration. Port Configuration In general, the selected communications port should be configured in accordance with the requirements of the communications channel as described in ConfigWiz Users Manual (UM- 2012). However, the following two parameters are protocol-specific and should be configured using the procedures below: 1. Select Ports from the Components menu. The Ports selection window displays. NOTE The port is arbitrary. The port used by the DNP3.0 client on your system may differ. 2. Then select the port(s) used by the DNP3.0 client and click Select. The Port Options window displays. 3. Click the SPECIAL tab. Copyright 2001 QEI, Inc. 9

10 ConfigWiz Addendum 4. Enter the following configuration information. Field Name Parity RtsCts Delay PushTo Talk Enable CTS Timeout Parameters 8/No (This is the default parameter and it may already be set correctly.) 40 (This is the default parameter and it may already be set correctly.) Yes/No. Default is No. Yes/No. Default is No. Port speed Timeout Value 1200 bps 6000 ms 2400 bps 3000 ms 4800 bps 2000 ms 9600 bps 1000 ms (For higher speeds use 1000ms.) 5. Click Apply to enter the changes. 6. Click OK. 7. Click Exit on the Ports selection window. 10 Copyright 2001 QEI, Inc.

11 ConfigWiz Addendum Field Device (IED) Configuration Use the following procedure for configuring the field devices for the DNP3.0 client: 1. Click on the field device icon in the ConfigWiz main window. 2. The IED Options configuration window displays. Copyright 2001 QEI, Inc. 11

12 ConfigWiz Addendum Analog Tab Select the ANALOG tab. The point scaling parameter fields display. QEI s DNP3.0 client provides for the normalizing of each received integer value to a fully scaled, signed 16-bit binary integer. In many IEDs, the engineering values represented by binary integers are not scaled to the maximum value. To normalize the values, the full-scale engineering value should be entered for each point in ConfigWiz. Select the parameter entry field and change the value as needed. The value can range from 1 to 32-bit binary value. If there is a problem selecting the parameter field for point #1, first select point #2, then reselect point #1. 12 Copyright 2001 QEI, Inc.

13 ConfigWiz Addendum Control Duration Tab Select the CONTROL DURATION tab. Enter the desired contact closure time for each output point. If the value is not known or if it is not critical, leave the default setting of 2000 ms. Copyright 2001 QEI, Inc. 13

14 ConfigWiz Addendum Control Type Tab Select the CONTROL TYPE tab. The data acquired by the DNP3.0 client is usually routed (mapped) to a Master Station Server that operates in the Select Before Operate (SBO) mode. However, the Field Device connected to the DNP3.0 client may not be capable of operating in SBO mode. The control type required by the client can be configured in the client, regardless of the master station s operating mode. Select the desired mode on a per point basis via the pull-down menu as shown on the screen below. Setpoints Tab The same procedure applies to Setpoints, which are analog controls. Select the SETPOINT tab to prompt the window for control type selection, and then select the desired mode using the pull-down menu. 14 Copyright 2001 QEI, Inc.

15 ConfigWiz Addendum Standard Tab Select the STANDARD tab. The configuration parameter for each field is described below. Field Name Address Port Number Misc Flags Response Timeout Inhibit Point No Description The address of the Field Device (IED). This should match the address configured in the device. Enter the port number the Field Device (IED) is physically connected to. This must be one of the ports assigned to the DNP3.0 client. These flags are a set of communications control parameters. Their functions are listed below. The &h denotes that the number following is a hexadecimal number. It is recommended that the settings &h01 be used in most applications for L1, L2 devices. See Misc. Flags Bit Definitions. This is the time required to receive an application information packet (fragment) from the time of transmitting the polling packet. This time is a function of the communications channel speed and has to be configured accordingly. See Response Timeout by Channel Speed table. The address of the status point used by the Field Device to inhibit controls. Leave the default setting if this feature is not used. Copyright 2001 QEI, Inc. 15

16 ConfigWiz Addendum Field Name Static Poll Period Counter Poll Period E-Port Number Description The time interval in seconds between polls for static data (Class 0 or all data). If the client is polling for event data then a long period (several minutes) between Static Data Polls is appropriate. If the client is not polling for event data then the static poll interval should be shorter (10 to 15 seconds). The period of accumulator polls (several minutes may be appropriate). If the selected PortNumber is e-port, then this field should contain the specific number of the e-port to be used for this device. 1 to 127 e-ports can be selected. Misc Flags Bit Definitions Bit Bit 0 Bit 1 Definition The least significant bit, is used to enable class poll for events. If this bit is set to a one (1) the client will poll for events (Classes 1,2,3). If it is set to a zero (0) the client will only poll for static data (all data, Class 0). Some IEDs do not support polling for events. Used for configuring link layer acknowledgement. If this bit is set to a one (1) the client will ask the Field Device to confirm the receipt of the message. In general, link layer acknowledgements should not be used in transmissions from the Client to the IEDs. Bit 2 Used in conjunction with control inhibit. A specific status point from the IED can be used to inhibit controls from the Client to the IED. Bit 2 specifies which state of the status point will inhibit the outgoing control. The default setting is 0 and should be left as the configuration parameter if the inhibit function is not used. Bit 3 Used to inhibit polling of the IED. This can be used for troubleshooting purposes. Normally, the IED is polled for events, static data and counters depending on the configuration. It may be useful to disable the polling of an IED while maintaining all the other configuration. If the value of Bit 3 is one (1) the polling of the associated IED is disabled. The default is zero (0). Bit 4 Bit 5 Used to disable counter (accumulator) polling. When accumulators are defined in the Sizing DNP3C#n dialog box the Client will poll for counters in accordance with the programmed time interval (see Counter Poll Period). There are implementation levels which do not support this function but send the counter values in response to a static data poll (Class 0). In that case it is necessary to disable the counter poll in the Client by entering a value of 1 for Bit 4. The default is 0 which enables counter poll. Used to disable event poll during static data poll. The Client normally polls for static data (all data) by polling for all four variations of object 60 (Class 1,2,3,0) which means that event data is also acquired as part of the poll. Some implementations do not respond to class poll other than Class 0. In these cases the the poll for Class 1,2,3 as part of the static data poll should be disabled by setting Bit 5 to 1. The default value of Bit 5 is Copyright 2001 QEI, Inc.

17 ConfigWiz Addendum Response Timeout by Channel Speed This is the time required to receive an application information packet (fragment) from the time of transmitting the polling packet. This time is a function of the communications channel speed and has to be configured accordingly. Channel Speed Timeout 1200 bps ms bps ms bps 8000 ms bps 6000 ms. Driver Configuration Use the following procedure for configuring the drivers for the DNP3.0 client: 3. Select the Driver button at the bottom left on the IED Options configuration window. The driver configuration window displays. Copyright 2001 QEI, Inc. 17

18 ConfigWiz Addendum AppLayer Tab Field Name AppLayer MaxRetries Service RequestTime Control ApertureTime Description If the inbound message from the IED fails the client will poll again for the information. This parameter defines how many times the client should retry to obtain the information from the IED. In general, the initial poll and two retries should be sufficient. The AppLayer retries should be coordinated with LinkLayer retries to obtain the best communications efficiency. If LinkLayer retries are used then AppLayer retries should be limited to one. If two or more ApplLayer reties are used then LinkLayer reties should be none. This time must be longer than the Port Timeout and should be coordinated with the communications speed as listed under the Service Request Time Parameters. After receipt of a selection command in a SBO control sequence, the execute command must be received within the ControlApertureTime in order to be accepted. Typical value is 30 sec. 18 Copyright 2001 QEI, Inc.

19 ConfigWiz Addendum Service Request Time Parameters Speed Service Request Time 1200 bps ms 2400 bps ms 4800 bps 5000 ms 9600 bps 3000 ms LinkLayer Tab Field Name Rtu Address LinkLayer MaxRetries Description The DNP3.0 protocol requires both Source and Destination Addresses. This entry is the Source Address of the Client. QEI default is 1024 or &h400. This is the maximum number of polling attempts at the link layer level. Usually, if Application Layer retries are used, there is no need for link layer retries and this parameter should be set to zero (0). Copyright 2001 QEI, Inc. 19
