Expandability; Additional Resources; Communication Channels - LOVATO ELECTRIC DMG700 Manuel D'application

EXPANDABILITY

– Thanks to expansion bus, the DMG700 can be expanded with EXP series modules.
– It is possible to connect a maximum of 4 EXP... modules.
– The supported EXP modules can be grouped in the following categories:
• Communication modules.
• Digital I/O modules.
– To insert an expansion module:
• Remove the power supply to DMG700.
• Remove terminal covers and the 8-pole terminal block.
• Remove the protection cover of one of the expansion slots.
• Insert the upper hook of the module into the fixing hole.
• Rotate the module body downwards, inserting the connector on the bus.
• Push until the bottom clip snaps into place.
• Re-install the terminal block and transparent terminal covers.
– There is no sequence for module insertion.
WARNING!
When the EXP module is installed on a DMG series multimeter, it is mandatory to install the sealable terminal covers supplied with the multimeter.
– When a DMG700 is powered on, it automatically recognises the EXP 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 will be saved and will become effective; otherwise the mismatch will be shown at every subsequent power-on of the multimeter.
– The current 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 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.
1 - No. and status of communication channel
2 - Type of the expansion module
3 - Numbering and status of the I/Os

ADDITIONAL RESOURCES

– The expansion modules provide additional resources that can be used through the dedicated setup menus.
– The set-up 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 typology (for instance two communication interfaces), the set-up 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.

COMMUNICATION CHANNELS

– The DMG700 supports a maximum of 2 communication modules, indicated as COMn. The communication setup menu M07 is thus divided into two sections (n=1 and n = 2) of parameters for the setting of the
ports.
– The communication channels are completely independent, both for the hardware (physical interface) and for the communication protocol.
– The two channels can communicate at the same time.
