Configuration Files
WSOS holds the configuration of each Recloser or Load Break Switch in a separate switchgear configuration file.
In the “Off’-Line” mode, WSOS works with the data in this file.
This enables configurations to be up-loaded from the switchgear and examined off line at a later date and for configurations to be set up “Off-Line” and later down-loaded into the switchgear in the field.
Working Directory
When opening files WSOS searches the current working directory to find switchgear configuration files.
The working directory defaults to the installed WSOS directory (c:\wsos) but can be set using the Customise-Working Directory command.
Any new switchgear that is created is stored in the working directory.
This allows the user to set up multiple working directories that reflect their requirements.
Switchgear Files
WSOS creates multiple data files for each item of switchgear.
The most important is the configuration file which has the name given to the switchgear and a “.sos” extension.
All the files for each switchgear item are stored in a directory under the working directory that is the name of the switchgear.
C:\WSOS

ACR.sos
File - Copy
To pass a set of files to another user on a different PC the whole directory for that device should be copied.
The File-Copy option is provided for this purpose.
The copy option allows the user to specify if only the configuration file is to be copied or if the history files are also to be copied.
File
Selecting Copy Source and Destination
Configuration Files: These are the files which contain the configuration and protection settings for the switchgear.
Event Log: These are the event log files which have been uploaded from the switchgear.
History Files: These are the weekly and average files which have been uploaded from the switchgear.
File – Save As
To make a configuration file for a new device from an existing one use the File-Save As command.
This is the best way to make new devices based on a standard configuration.
File
File Tips
In general, keep in mind the following points regarding switchgear configuration files:
A separate configuration file should be kept for each item of switchgear WSOS administers and this file should be maintained to match the configuration of the switchgear.
The File-New command creates a new file with the default configuration.
The File-Save As command creates a new file based on an existing one (but does not copy the historical files).
The File-Copy command is used to write or read a switchgear configuration to/from floppy disc for use on another computer. This command can copy not only the configuration files but also the history files.
Compare Switchgear Settings
The command Options-Compare Switchgear Settings compares the settings between the current switchgear configuration file and the “On-Line” switchgear.
Any fields with conflicting values or settings are displayed.
This function is useful to check if the switchgear and configuration files are in alignment without risking overwriting either the settings or the file.
Options
History - Introduction
The Nu-lec intelligent switchgear controller records historical information such as event log and maximum demand records.
This data can be extracted (up-loaded) from the controller by WSOS.
There are two advantages in this: There is limited memory on the controller for
this data. This means that if it is not extracted within certain time limits (eg. six months) then it will be overwritten with more recent data and lost. Up-loading to the computer’s disc give practically unlimited memory for this data.
WSOS provides user friendly displays of this data and can export the data in file formats suitable for spreadsheets or other PC programs for further analysis.
History Files
There are five types of information that can be up-loaded. They are :
Event Log - Contains the date and time of all significant events that occurs in the switchgear.
Weekly Data - Contains the total kWH, the peak kW, time of this peak and the power factor.
Monthly Data - Contains the total kWH, the peak kW, time of this peak and the power factor.
Average Data - Contains the kW, power factor, A, B and C phase currents for the averaging period.
Configured Historical Data - Contains the data configured by the engineer for the configurable averaging period.
History Upload
The history dialog box on the menu bar provides access to the history data.
The on-line help details how to upload the data.
History Upload Display
Current Records: This field shows the current number of records that are stored on the disk for the Event log, Weekly and Average historical data files. This field is read only.
Stop Date: The date of the earliest record to be uploaded.
Delete Old Records: This field shows whether to delete all the existing records that have been up-loaded before. If this field is not set the up-load is added to the existing upload.
Upload:This button when pressed will start uploading records from the switchgear. This button is only displayed when On-Line.
Uploading Event Log RecordsWhile an upload is in progress, two additional lines are displayed:
The current date/time of the last record uploaded and the total number of records uploaded.
The time taken so far Stop Upload This button when pressed will stop an upload from a switchgear. This button is only valid when an upload is in progress.
View: This button when pressed will display any records uploaded from the switchgear. The information is displayed in a table. This button is disabled when an upload is in progress.

Customised Data Logging
Transfer of Historical Files between Computers
It is likely that the data is to be collected from the switchgear on a different PC from the one used to build up the record.
For example a technician may collect the data every four months using a notebook computer for adding to the records on a protection engineers desktop PC.
The correct sequence to carry this out is as follows:
Engineer used File-Copy command to copy all files to the memory stick that is given to technician.
Technician visits the switchgear, connects directly and goes “On-Line” .
Technician up-loads historical files which appends data to the files on the memory stick.
Engineer uses File-Copy command to copy the files back to his hard disc.
Communications - Introduction
Before going “On-Line” a communications link must be available between WSOS and the required switchgear.
Depending on the operating level purchased, the following connection methods are available.
Direct
Modem
Radio
Communications Configuration
Direct Connection
This method uses a direct RS232 link to the switchgear.
In this configuration, a serial cable connects the computer serial port to the serial port on the Operator Control Panel on the switchgear.
When “On-Line” WSOS polls the switchgear every few seconds and refreshes the data displayed on the screen.
The polling rate is set with the Customise-Poll Period command.
Modem Connection
WSOS also provides the capability of controlling switchgear over a telephone link.
This allows switchgear with a telephone connection (including cellular phone) to be “Dialled-up” and controlled remotely.
Note that the correct telephone number for the switchgear must be entered on the Customise - WSOS Communications page.
33114422
Modem Message Lengths
Short Poll requests will be sent as individual messages. This will slow down comms with the CAPM because of the extra overhead.
For Normal, poll requests are grouped together and sent as one message. The read file has one request per message. The write file has one command per message.
For Medium, multiple poll requests are grouped together and sent as one message. The read file has multiple requests per message. The write file has multiple commands per message.
For Long, multiple poll requests are grouped together and sent as one message. The read file has multiple requests per message. The write file has multiple commands per message. The only difference is that the messages are longer to reduce the total number of messages sent.
Communications Setup for Modems
Modem Initialisation: This is the command string sent to the
modem every time WSOS goes On-Line to this device.
Dial Command: This is the command string sent to the
modem to commence dialling. (Do not include the phone number in this field).
Hangup Command: The first command string is sent to get
the modems attention (go from on-line state to command state). The second command is used to hang up the modem.
Response Time: This is the time WSOS will wait for a valid
connection between the CAPM modem and WSOS's modem.
Modem Connection to Communications Port P9
Modems for remote communications are normally connected to P8 via a cable which runs to the radio tray.
A modem can also be connected to P9 which is normally used for direct WSOS communications at 19200 baud.
In this case P9 will have had its Mode and Baud Rate reconfigured

Radio Connection
WSOS allows control of switchgear over a voice frequency (VF) radio link. The link can be dedicated to WSOS or can be shared with voice users.
In a radio link like this all the devices being controlled receive the messages sent by the WSOS over the radio channel.
WSOS addresses the required recloser or Load Break Switch by sending the unique serial number of the electronic controller.
This is entered on the Customise - WSOS Communications page before going “On-Line”.
For a radio link that also is used for voice, set the poll period to one hour or longer as required.
Questions How many levels of passwords exist in WSOS?
2 levels What is the name of the directory that WSOS searches to find switchgear
configuration files? The Working Directory
Which File Command is used pass a set of switchgear files to another user’s PC?
File – Copy Which File Command is used to creat a file for a new switchgear based
on an existing configuration? File – Save As
What effect does ticking ‘Delete Old Records’ have on an Event Log Upload?
Previously uploaded events are erased from the PC memory. How is addressing achieved with WSOS Radio protocol?
The CAPM Serial number is used as the communications address.
