identified as DI_CONTROLLER_01). In the PLC program, it is possible to associate
symbols (nicknames) to the resources. It is possible to view the symbols in the second
column, in place of SICES codes: press
ACK/ENTER
(as to select a different PLC
block) and press ◄►; confirm with
ACK/ENTER
button. See the PLC documentation
for the description of the SICES codes for the identification of the PLC resources.
•
The third column shows the current value of the resource. For digital resources, if the
value is shown in REVERSE, it means that the relative parameter is denied.
This page shows to status of all virtual digital inputs (that is, those inputs the status of which
has not been acquired by the hardware, but is determined by the PLC program).
This page shows the status of all temporary digital variables (DT_XXX) available for the PLC
program. Many pages which alternate every 2 seconds are available to view all digital flags.
Keeping
ESC/SHIFT
pressed, you can stop the rotation of the pages (keeping on the display
the page currently viewed).
This page shows the value of all the internal states of the controller (ST.XXX) available for the
PLC program.
This page shows the value of all the virtual analogue inputs of the controller (i.e. those inputs
whose value is not acquired by the hardware but is determined by the PLC program).
This page shows the status of all numeric temporary variables (AT_XXX) available for the PLC
program. Several pages are available which alternate every 2 seconds to display all the
numerical data. Pressing and holding the
ESC/SHIFT
button prevents pages from rotating

key. It Contains:
The operating mode of the controller (MAN, AUTO etc.).
The state (absent / present / in tolerance) of the voltages/frequency of renewable sources.
The state (absent / present / in tolerance) of the voltages/frequency of common bars.
The reasons that prevent the closure or force the opening of the RNCB circuit breaker.
The status of the command sequence of the RNCB circuit breaker
The reasons prevent starting or which force the inverter to stop.
The status of the command sequence of the inverters.
The possible activation of the OVERRIDE of the protections.
For some of this information, a time is also shown; for example, during the stop cycle of the
inverters the time remaining at the end of this cycle is shown.
