Only oneactive transaction, from LHMI or PCM600, is allowed at a time.With the individual tool components, you can perform different tasks and functionsand control the whole substation. PCM600 can operate with many differenttopologies, depending on the customer needs.For more information, see PCM600 documentation.4.4.1 Connectivity packages GUID-D480127C-3F19-44A3-9A6F-A8549C02CDCD v1A connectivity package is a software component that consists of executable codeand data which enables system tools to communicate with an IED. Connectivitypackages are used to create configuration structures in PCM600. The latestPCM600 and connectivity packages are backward compatible with older IEDversions.A connectivity package includes all of the data which is used to describe the IED,for example, it contains a list of the existing parameters, data format used, units,setting range, access rights and visibility of the parameter. In addition, it containscode which allows software packages that consume the connectivity package toproperly communicate with the IED. It also allows for localization of text evenwhen its read from the IED in a standard format such as COMTRADE.Update Manager is a tool that helps in defining the right connectivity packageversions for different system products and tools. Update Manager is included withproducts that use connectivity packages. Update Manager is a part of PCM and isdelivered with it.1MRK 500 128-UEN B Section 4Overview650 series 2.2 IEC 37Operation manual
