Question: Can the DL205 expand beyond the local rack?
Answer: The D2-250(-1), D2-260, and D2-262 CPUs can be expanded using the D2-EM and D2-CM modules. See the DL205 User Manual Local Expansion I/O in Chapter 4 for details.

Another method the I/O can be expanded is by adding remote I/O with the D2-240, D2-250(-1), D2-260, and D2-262.

The D2-240 uses the D2-RMSM (Remote Master) module.
  • A total of 896 I/O points are available by using 2 Remote Master modules with 7 slave per module.

The D2-250 and higher uses either the D2-RMSM module or the bottom port of the CPU.
  • A total of 2048 I/O points are available using up to 7 Remote Master modules and the CPU port with 7 slaves per module and the CPU.

You can also use the H2-ERM100 for the D2-240 and above processors. The H2-ERM100 uses ethernet for the remote I/O expansion.

The D2-230 can not be expanded beyond the local rack.

Question: Does the D2-RMSM module consume any I/O?
Answer: No, the D2-RMSM does not consume any I/O.

Question: What is the maximum number of H2-EBC modules that the H2-ERM can support?
Answer: 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.
