SSE OPC and DATABASES

Overview…

• Setup the SSE OPC to save data to a MS Access database file (mdb)• Setup the SSE OPC to save data to MS SQL database

THE MAIN DIFFERENCE BETWEEN ACCESS AND SQL IS YOUR DATABASE SETUP.

TO SAVE THE ACTUAL DATA POINT TO THE DATABASE, IS EXACTLY THE SAME FOR ACCESS AND SQL.

Access Setup

Location in SSE OPC:

On the CHANNEL setup, you will find a ‘DATABASE SETUP’ tab.

Database File Name:

The SSE OPC will create a Access MDB file with the name entered in this field - example AccessDB.mdb

Database Path/ODBC-Name:

The path where the user wants to save the MDB file

NB!!!! YOUR PATH MUST HAVE A ‘\’ AT THE END

Database type:

Set this field to ‘MS Access Direct’ – this informs the SSE OPC that it must try and connect to a MS Access database file

DB User Name:

If the Database file was created with a User Name, you can enter the User Name here and the SSE OPC will connect to the Access database file with the correct User Name

Access Setup

DB User PW:

If the Database file was created with a Password, you can enter the Password here and the SSE OPC will connect to the Access database file with the correct Password

Use Oracle Standards:

To ensure that the SSE OPC does not use reserved words as field names in the Database.

If you are unsure of this setting, enabled it.

Field Setup:

When you double click on that field, a new screen will pop up.

Access Setup

Use It:

The user can choose which values will be saved in the Access Table by the SSE OPC

Field Name:

The user can setup custom field names that the SSE OPC will create in the MS Access Table

Access Setup

Tag Name Format:

If the Channel, Device and TagName ticks are enabled the SSE OPC will take the Channel Name add a ‘_’, followed by the Device Name and finally adding the Tag Name

Example above:

Channel was not enabled

Device was enabled – ‘BULSK’

Tag Name was enabled – ‘LOAD_VOLT’

thus – BULSK_LOAD_VOLT

Data Points to be Saved to a Database File

AINs, DINs, CINs and FINs are data points that supports database logging (saving)l

DB Table Name:

The user choose a name for the MS Access Table that will be created by the SSE OPC

DB Log Dead-Band:

Specifies the value that the EU Value should change before it will be logged into the Database

DB Log if < 0:

When data is received by the SSE OPC from a RTU, it will check the value of each entry. If the "DB Log if < 0" is selected the SSE OPC will log all ranges of the incoming value to the DB.

Data Points to be Saved to a Database

FileDB Log Events:

When the SSE OPC receives an event from an RTU, it checks whether the "DB Log Events" is

checked. If so, the SSE OPC will handle the Event and write it to the database.

DB Log Poll:

When the SSE OPC polls the registers of a RTU, the SSE OPC will only write data to the database when this option is checked.

DB Log Logger:

If selected, the SSE OPC will save the RTU Logger data to the database.

(Works together with Log Delay Interval Channel, Address & Port Settings, Log Delay Interval)

Log Data to OPC:

Every time the SSE OPC receives Logger data from a RTU, the SSE OPC checks whether this option is selected. If selected, the Log entry will be written to the OPC Foundation Level along with the Logger Timestamp.

Log Data to EU Val:

Every time the SSE OPC receives Logger data from a RTU, the SSE OPC checks whether this option is selected. If selected, the EU Val will be updated with Logger data.

Data Points to be Saved to a Database

FileLog Alarm Zones to DB:

An Alarm Zone can have a value of 0 to 4. they represent in sequence "LoLo", "Lo", "Normal", "Hi", and "HiHi" Alarm States. When an Alarm occurs the RTU will send the Alarm Zone to the SSE OPC. If enabled, SSE OPC write the Alarm zone State's value to the database.

Log Events Counters to DB:When enabled, the SSE OPC will save that specified Data point’s ‘Event Counter’ to the database before the SSE OPC reset the event counter.

Database File Name:The name of your MS SQL Database

Database Server NameThe name of your SQL Server name (Usually your PC name)

Database Type:Set this field to ‘MS SQL Server Direct’ – this informs the SSE OPC that it must try and connect to a MS SQL database file

MS SQL Setup

MS SQL Setup

DB User Name:Enter the User Name here and the SSE OPC will connect to the SQL database file with the correct User Name

DB User PW:

Enter the Password here and the SSE OPC will connect to the SQL database file with the correct Password

Use Oracle Standards:

To ensure that the SSE OPC does not use reserved words as field names in the Database.

If you are unsure of this setting, enabled it.
