Question: Can the DL205 expand beyond the local rack?
Answer: The D2-250-1 and D2-260 CPUs can be expanded using the D2-EM and D2-CM modules. See the DL205 User's 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, D2-250-1 and D2-260. 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.

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

Question: I need to add another module to my DL205 9-slot base, but the rack is full. What can I do?
Answer: 1.- D2-250-1 and D2-260 are the only CPUs supporting local expansion. You need to change the base D2-09B to D2-09B-1 if this is the case.
2.- You can use ERM/EBC system with all CPUs except D2-230.
3.- A D2-RMSM with a D2-240, a D2-250 and a D2-260, or the bottom port of a D2-250(1) or D2-260 CPU can serve as a remote I/O master. The D2-RSSS serves as the remote slave and resides in the CPU slot of the remote base. Since this is true remote I/O, the scan is handled differently than local I/O.The D2-230 does not support remote I/O.

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.
