For integrators, developers and others using OPC, MatrikonOPC Explorer is a utility used to help test and troubleshoot OPC servers and connections. Unlike other, cumbersome OPC clients, the MatrikonOPC Explorer utility is easy to install and simple to use. MatrikonOPC Explorer will tell the user which OPC interfaces are supported in their OPC Server. This will include DA, HDA, Alarms and Events (A&E), and OPC Security. This version is the first release on CNET Download.com.
