Introduction This document is a step-by-step guide for configuring the RTU 6049-E70 for Railway Traction applications. The various options required are explained and their configuration procedure described. The HUSKY RTU Configuration Tool version 2.0 (Railway Build) shall be used for this purpose.
1. Select File→ New menu option, the following window will open 2. It will create the file at the specified location with the specified name, as in the
following window. 3. The file will be created with the extension klk 4. Press OK
5. Select Project → RTU Type menu option, and choose the appropriate RTU
Configuring Serial Ports 1. Select the CPU module from the main rack. 2. Properties specified to the module will be shown in the bottom window. 3. Select the “Ports” tab. It will look similar to the following picture.
4. Specify the desired serial port parameters. The typically used values are listed
below.
Port No.
Baud Rate
Data Bits
Stop Bits
Parity Flow Control
RTS Pre-
amble
RTS Post-
amble
Interface Purpose
1 9600 8 1 None No 0 0 RS232 Unused 3 600/1200 8 1 None Yes 0 10 RS232 Modem 4 9600 8 1 None No 0 0 RS232 Power
1. The default configuration settings for most of the I/O modules are suitable for our application.
2. To configure an I/O module, select the desired module by selecting the slot on which it is configured. The module properties will be shown in the bottom window.
3. I/O Address: To change the I/O address of an I/O module, double click on the “Memory Address” parameter. A dialog box will be shown wherein the required address can be specified. Note: it is NOT recommended to modify the default address, unless specifically required.
1. Sequence of Events (SoE): By default all digital inputs have SoE marked on them. For immediate reporting to master station with RTU timestamp, this option must be checked for the required inputs. This can be accessed from the SoE property of a DI module.
2. Input Filter Time: Input filter
time is used to suppress event generation in case of chattering of inputs. An input is considered to have changed only if the new value remains constant for the specified filter time.
1. Output Type: The digital output module supports different output types – latched, pulsed, SBE. For our application we require the Select-Before-Execute (SBE) option.
2. Pulse train: On initiation of a command, the DO module can generate a pulse train. This however, is not requried for our application. Hence, we specify the number of pulses as one. The “High Duration” parameter specified the period for which the output will remain high.
1. Active Channels: Depending on the number of channels that are to be used, the channels are marked as active. Inactive channel are neither sampled nor any alarm processing done on them.
2. Alarm Address: Under-voltage alarm
(catenary alarm) is raised for active channels based on the setting made on the module. The alarm status is configured as a digital input under this module. By default keep this address as %DI0097-%DI0112.
Configuring Memory Variables Memory variables are used by the RTU for different purposes, including performing calculations using logics, and for data acquisition from other devices.
1. In Project Explorer, expand the “Config” option.
2. Click on “Variable Config”.
3. The different variable types (memory types) can select from the combo box as shown in the previous picture. Except for name other properties are editable and can be set by the user.
4. The following table lists the variables used by the RTU for our application. Each of these variables have to be set accordingly.
Address Type Description Other Properties Purpose %BV0001 BV Delayed AC
FAIL Alarm SOE = Yes This is a logic calculated
variable which triggers AC fail alarm after a preset delay. If the alarm is normalized before this delay then value is not set. ON = NORMAL OFF = ALARM
%BV0002 BV Delayed DC Low Alarm
SOE = Yes This is a logic calculated variable which triggers DC Low alarm after a preset delay. If the alarm is normalized before this delay then value is not set. ON = NORMAL OFF = ALARM
%I16V1950 I16V PT Ratio x 100 Initial Value = PT Ratio x 100 E.g.: If PT Ratio is 27.5kV/110V, then Initial Value = 27500/110 x 100 = 25000
This value is used for scaling the voltage values acquired from the power transducer as per the PT ratio of the potential transformer connected to power the transducer.
%I16V1951 I16V CT Ratio x 100 Initial Value = CT Ratio x 100 E.g.: If CT Ratio is 750A/5A, then Initial Value = 750/5 x 100 = 15000
This value is used for scaling the current values acquired from the power transducer as per the CT ratio of the current transformer connected to power the transducer.
%I16V2047 I16V U/V Trip Delay Initial Value = 5000
This value specifies the delay (in milliseconds) between detection of under voltage condition and corresponding trip action of the bridging BM.
Configuring Devices For each type of device that the RTU will communicate with, a device template has to be created. This template helps identify the device during configuring the protocols that the RTU will operate on.
1. In Project Explorer, expand the “Config” option.
4. Specify the slave ID of the RTU in the “Slave ID 1” field.
5. To specify the mapping between the RTU I/O and SPORT protocol, an I/O list needs to be created.
6. To create an IO list, press “IO List Creation” button. The following window
will be opened.
7. Press the add button to create the new row in the IO List Configuration. 8. Set all the values as shown below (for TSS).
a. Sr. No 1, DI (1-96) is for Digital Indication b. Sr. No 2, DI (97-104) is for Catenary Indication. c. Sr. No 3, DO (1-48) is for Commands. d. Sr. No 4, AI (1-8) is for Analog Values. e. Sr. No 5, DI (1-3) is for delayed AC Fail, delayed DC Low. f. Sr. No 6, AI (11-26) is for Transducer Analog Values.
9. Set all the values as shown below (for SP/SSP). a. Sr. No 1, DI (1-32) is for Digital Indication b. Sr. No 2, DI (97-104) is for Catenary Indication. c. Sr. No 3, DO (1-16) is for Commands. d. Sr. No 4, AI (1-8) is for Analog Values. e. Sr. No 5, DI (1-3) is for delayed AC Fail, delayed DC Low.
