What is the maximum number of H2-EBC modules that the H2-ERM can support?
When Using a D2-250 or the D2-240 as the controller, the H2-ERM can support up to 16 H2-EBC units. When the any of the Think ‘N’ Do Live or Studio WINPLC versions are used, the number of H2-EBC modules is limited to only one. The WinPLC with Think & Do Live Software or Entivity STUDIO has the ability to support higher level functions such as peer-to-peer networking,PID loop control, data communications via OPC, high speed counter operations, as well as multiple serial ports via the H2-SERIO module. As a result we request that any application that requires more than one H2-EBC base modules connected to an H2-ERM should be reviewed with the Entivity technical support manager. Therefore, the default support for the H2-ERM product is one H2-EBC per H2-ERM. While it is physically possible to go higher, there are some limitations and issues that must be understood prior to applying the product beyond one expansion base. The Entivity technical support manager can be reached at 734-205-5401.
