Change from standart project to Redundancy Project

[hakan]

Hi,

We are using WinCC OA 3.14. We have developed project as standart project. Now we have to change the standart project to redundancy project.
Is it possible.?
Is there any document for this issue?

Hi ,

Yes that is possible , and in wincc OA that is considered to be so flexible and easy.


1) Open the config file of your standard project and paste the following entries under general section ( fill "First-PC$Second-PC" with the actual host names of the redundant pair):

data = "First-PC$Second-PC"
event ="First-PC$Second-PC"

2)Add three managers:
-REDUNDANCY MANAGER
-SPLIT MODE MANAGER
-Control Manager : fileSync.ctl -event "first-PC" -data "first-PC"

3) make the project shareable
4) go to the second host and create new project of type( copy of redundant project) OR Copy the project from the first pc to the second pc with the same path and register it .

For the basic settings you just have to modify the config file, that is correct.
If you want to make a single project a redundant one you have to do more than just editing the config file.

Molst of the WinCC OA standard panels for the configuration of the project (archives, drivers, ....) write only to the datapoint and its elements which are used for the server 1 in a redundant system. Copying the values is then made automatically by copyDp/copyDpType entries in the config.redu files. These config entries are only used in redundant systems.
In some panels a check is made if the system is redundant and based on the information the datapoint elements are set for server 1 and 2 in a redundant system.
If the system is not configured redundant the datapoints for server 2 therefore do not have the configuration.
When the system is now made redundant the information for server 2 is missing and the system will not work properly.

To ensure that the system is configured correctly you have to
-- make the system redundant by the configuration of the data/event entry in the config file
-- start the project at server 1
-- check all the configuration made for your system (e.g. archives, drivers, ...)
-- stop the project
-- copy the project to the redundant partner

Defined some modbus driver in standart project. When changed to redundancy project, have to create modbus driver(for example _Mod_Plc_3_2) for redundancy system manually?

or Can be defined to automatically creating in config.redu? How can be done this.

Thank you

You can use the WinCC OA standard panels for the configuration.
If the system is configured redundant the required datapoints will be created automatically when doing the configuration, e.g. for the Modbus driver.

There are modbus drivers that before defined in standart project.
After changed standart project to redundancy project Is there any way automatically create modbus drivers for host 2?

[leoknipp]

Have you checked if the datapoints are created when doing again or confirming the current Modbus configuration using the driver panels in the System Management?
