Dataloggers Limits of dataloggers are set by their implementation in the drives. There are some limits in DriveWindow, too. Maximum number of dataloggers in a drive: No limit in DriveWindow 2.30 itself, but DriveOPC 2.09 limit is 10. Older versions: 2. Maximum number of logged variables: 6. Maximum absolute value of yaxis minimum and maximum: 3.40282356779733642751e+038. Maximum length of the x-axis: 32700 * interval. Miscellaneous DriveWindow 2 9-33 4.1.6 Maximum Number of Item Sets DriveWindow limits the number of item sets that can be present in the item sets pane as follows: ? Maximum total number of item sets is 9. ? There is exactly one item set of type browsed items. ? Maximum number of item sets of type all faults is one. ? Maximum number of item sets of type all events is one. 4.1.7 Support for ACS880 Family of Drives DriveWindow 2.40 (and newer) has limited support for ACS880 family of drives in case using the DriveDA OPC sever (not included in DriveWIndow) is installed. The limitations are as follows: ? No system software backup, restore, or load. ? Parameter download should be avoided. ? Only default language (English) is supported. ? Drive names must contain Latin alphabet only. ? No dynamic parameter support. ? Dataloggers cannot be configured, just controlled. ? Only six channels of a datalogger can be shown. ? Only six channels can be monitored (ACS880 monitorlogger is used if possible).

DriveOPC DriveOPC is an OPC Server based on OPC Data Access Standard 1.0A. It implements the obligatory custom interfaces and IOPCBrowseServerAddressSpace. In general, an OPC Server is a software module, which implements OPC data access specification made by OPC Foundation (www.opcfoundation.org). OPC stands for “OLE for Process Control”. According to OPC Foundation: Advanced Information 10-4 DriveWindow 2 The OPC Specification is a non-proprietary technical specification that defines a set of standard interfaces based upon Microsoft’s OLE/COM technology. The application of the OPC standard interface makes possible interoperability between automation/control applications, field systems/devices and business/office applications. Traditionally, each software or application developer was required to write a custom interface, or server/driver, to exchange data with hardware field devices.
