AutoReconnectActive

Write Read TwinCAT TIA

Network TCP/IP client ActiveClients One client

ns=2;s=DEPRAG Smart/Network/TCP/IP/ActiveClients/0/AutoReconnectActive

Determines whether the connection should be restored automatically after a connection loss.

Examples:

TwinCAT 3 example
TIA Portal example

In addition to the parameters already explained, the following variables must be created / transferred for the implementation in TwinCAT 3:

Beckhoff parameter:

bTcpIpReadAutoReconnectActive
A boolean variable that can be used to trigger the execution of the ReadAutoReconnectActive command.

bTcpIpWriteAutoReconnectActive
A boolean variable that can be used to trigger the execution of the WriteAutoReconnectActive command.

AutoReconnectActive
A boolean variable that determines whether AutoReconnectActive is true or false.

hrTcpIpAutoReconnectActive
This can be used to monitor the execution of the command. Error codes have the type HRESULT.

fbTcpIp
An instance of the "FB_TcpIp" function block supplied with the DEPRAG Smart library.

ClientId
A STRING(255) variable representing the ID of the client.

PointerToNodeValue
A variable of the type "POINTER TO BYTE", in which the value to be set is stored.

SizeOfNodeValue
A UINT variable containing the length of the value to be set.

ConnectionHandle
"ConnectionHandle" received when establishing a connection between DEPRAG Smart Server and your OPC UA client.
