EXPANDABILITY
– Thanks to its built-in optical infrared interface, the DMED310T2 can be expanded with EXM series modules.
– These modules have an optical interface on the left side for the connection to the base unit and a second interface on the right side for the connection of an
additional expansion module.
– It is possible to connect a maximum of 3 EXM... modules.
– The EXM... modules can be grouped in the following categories:
• Communication modules
• Digital I/O modules
• Mixed modules – Communication + digital outputs
• Memory modules.
– The modules can be connected to the base unit simply placing them side by side and then inserting the dedicated clips.
– The connection sequence is free.
– When a DMED310T2 is powered up, it automatically recognises the EXM... modules that have been mounted.
– If the system configuration has changed with respect to the last saved, (one module has been added or removed), the base unit asks the user to confirm the
new configuration. In case of confirmation, the new configuration is saved and will become effective; otherwise the mismatch is shown at every subsequent
power-up of the device.
– The actual system configuration is shown in the dedicated page of the display (expansion modules), where it is possible to see the number, the type and the
status of the modules.
– The integrated I/Os are shown under the symbol of the base unit.
– The expansion I/O numbering is shown under each module.
– The status (energised/de-energised) of every single I/O and communication channel is highlighted in reverse.
ADDITIONAL RESOURCES
– The expansion modules provide additional resources that can be used through the dedicated setup menus.
– The setup menus related to the expansions are always accessible, even if the expansion modules are not physically fitted.
– Since it is possible to add more than one module of the same type (for instance two communication interfaces), the setup menus are multiple, identified by a
sequential number.
– The following table indicates how many modules of each group can be mounted at the same time. The total number of modules must be less than or equal to 3.
