Question

I need to add another module to my DL205 9-slot base, but the rack is full. What can I do?

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.
