Timeout |
Default timeout for ADS requests | |
|
Maximum timeout for determining the runtime status |
A configured runtime is considered unreachable if a request takes longer than this timeout. | |
|
Runtime state check interval |
The state of each configured runtime is checked periodically. | |
|
Runtimes |
An ADS connection is established to all enabled runtimes. | |
|
Ignored PLC attributes |
Attribute pragmas are added to the JSON schema. The attributes configured here are hidden. | |
|
Visible runtime ports |
Target systems might many ADS ports. Most of them are rarely used in HMI projects. | |
|
Limit response size of ADS requests |
The PLC task is locked for every request. If the request is too large, the PLC cycle time might be exceeded. | |
|
Limit the number of ADS requests that can be bundled in one sum request |
The PLC task is locked for every request. If a sum request contains too many requests, the PLC cycle time might be exceeded. | |
|
Limit the number of ADS handles created by a sum request |
TwinCAT's handle buffer is not resized in the middle of a sum request. Creating too many ADS handles in a single sum request causes errors if TwinCAT's handle buffer is full. | |
|
Support incomplete writes by reading before writing |
Variables that are hidden or not set in the write request will be overwritten with an old value. Disable this setting to prevent side-effects and improve performance. |
