OpcPipe settings

Name of the Connection

Each connection must have a unique name that allows you to quickly identify it later in the Connections list.

For OpcPipe, some security settings can be specified.

Connection Active

You can disable a connection if it is not intended for communication with a PLC. Thus, it is possible to disable it temporarily without having to delete and redefine it.

Number of instances

Write allowed

If this option is disabled, this connection is read-only.

Number of Instances

Allows a certain number of simultaneous connections of an OpcPipe Server connection.

Password

When you establish a connection, the password is used for access control. It is encrypted during transmission over the network.

Memory limit

Each OpcPipe frame can have a size of up to 4 gigabytes. Usually, frames of that size are not required. Since OpcPipe must provide the memory for such frames, you can restrict this value in order to prevent reduced performance. This value should be selected in a way that it will not cause a frame of maximum length to be truncated.

If at runtime, this limit is exceeded, the data will be discarded and the communication partner will receive a corresponding message.

Optional Parameters

Send timeout

If the acknowledgment mode is used, this is the time within which the acknowledgment must arrive; otherwise an error is generated.

Use Send Acknowledge

In OpcPipe, you can use the acknowledgment mode that sends an acknowledgment to the sending station when data has been received.

This mode slows down communication and should only be used in cases where you need to make sure that all data has been received.

The mode should only be used if the destination station supports the acknowledgment mode as well, notifying the partner that a secured transmission has taken place.
