General System Settings

The dialog allows you to set general valid settings.

Reset Diagnostics

The diagnostic counters are then set to 0 again in order to be easier to observe.

Reload configuration

An updated symbol information can also be updated. It is necessary when the configuration or symbol files are edited with an text editor.

OPC DA server (only for Windows)

OPC DA server functions

Here the OPC DA functionality can be switched off and on. If switched off, the calls from the OPC client will hang or get errors because OPC DA is switched off.

OPC DA Topics are case sensitive.

Some OPC clients do not support this, so this can be disabled.

Note: In some languages, case-sensitive rules are not well defined.

System Topic

OPC System Topic

The predefined topic "System" exists in the list of the configured topics. If the topic is not needed, this can be disabled.

Attention: When switched off, no connection monitoring and statistics are possible via OPC.

Update system elements every second

This function is rarely called. However, if necessary, this can be updated every second.

Browse Arrays

All array elements are offered individually when browsing. For large and many fields this can be very slow.

If this is disabled, the array is offered as a whole when browsing.

However, the item syntax rules can still be used to address each item individually.

Symbol Import Settings

Add Element names in import

The datablocks, inputs, outputs and flags are grouped together, or grouping is omitted.

Import S7 instance data blocks

Normally, the instance DBs are not needed in OPC. So turn it on if needed.

OPC UA Settings

Accept untrusted certificates

For machine setup, it is helpful to accept untrusted certificates, which should then be switched off for normal operation.
