WAVEFORM PAGE
– This page graphically represents the waveform for the voltage and current signals read by DCRG8F.
– It is possible to see one phase at a time, selecting it with
and
keys.
– The vertical scale (amplitude) is automatically scaled in order to fit the waveform on the screen in the best possible way.
– The horizontal axis (time) shows two consecutive periods of the waveform viewed.
– The graph is automatically updated about every second.
EXPANDABILITY
– Thanks to the expansion bus, DCRG8F can be expanded with additional modules of the EXP series.
– It is possible to connect a maximum of 4 EXP… modules at the same time.
– The EXP… modules supported by DCRG8F are divided into the following categories:
• Additional steps
• Communication modules
• Digital I/O modules
• Analog I/O modules.
– To insert an expansion module:
• Remove power from DCRG8F.
• Remove the protection cover of one of the expansion slots.
• Insert the upper hook of the module into the fixing slit on the upper end of the expansion slot.
• Rotate the module downwards, inserting the connector on the bus.
• Push until the bottom clip snaps in place.
– When DCRG8F is powered, it automatically recognises the EXP... modules connected to it.
– 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 becomes effective, otherwise the mismatch will be shown at every subsequent power-up of the system.
– 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.
