Specifies a time-out for an answer on any call or access to an OPC server, such as writings, creation of OPC Groups, Tag creation, removal, or browsing, changes to Tag's Advise mode, etc. If this time-out is exceeded, E3 considers the server as locked (unavailable) and starts a reconnection process. The value of this property cannot be negative. Configuring this property with value 0 (zero) disables this time-out, causing all accesses to the OPC server to take an undefined amount of time, which may lock the whole application if this access is synchronous. Default value of this property is 10,000 (10 seconds). Applications created in previous versions, when loaded in the current version, assume the value 0 (zero) for compatibility reasons. This value must be carefully configured, so that it does not lock the whole application nor forces an unnecessary disconnection, if the OPC server is actually taking too long to respond to certain requests.
