WAVEFORM PAGE

– This page graphically views the waveform of the voltage and current signals read by the DCRG8.
– It is possible to see one phase at a time, selecting it with
– 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 its expansion bus, the DCRG8 can be expanded with EXP series modules.
– It is possible to connect a maximum of 4 EXP... modules at the same time.
– The supported EXP modules can be grouped in the following categories:
• Additional steps
• Communication modules
• Digital I/O modules
• Analog I/O modules.
– To insert an expansion module:
• Remove the power supply to the DCRG8.
• 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.
– At power up, the DCRG8 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.
