Turn the operation mode of the controller to
AUTO
or
MAN
: next access will get you
to the very same point.
WARNING: This procedure permanently reloads all factory parameters according
to access rights.
Sometimes, it may be useful to reload parameters factory values. To do so, first access
programming, then press and hold the
ACK/ENTER
and
ESC/SHIFT
buttons simultaneously
for five seconds. Reload of factory values will be confirmed by a message on the display.
Factory values are reloaded only for parameters for which you are granted access
rights.
Pages from L.01 to L.07 contain the information related to the PLC logic and are only displayed
if on the controller is installed a valid PLC program. Refer to [6] for information on PLC.
This page contains information of identification of the PLC program installed in the device, as:
•
The firmware version of the PLC, compilator and editor.
•
The date of the last modification.
•
The medium/maximum time of execution. These times are reset automatically when
the PLC program is sent to the controller, or it is possible to force the reset by pressing
ACK/ENTER
+
ESC/SHIFT
at the same time for five seconds.
•
The title of the PLC program.
This page shows information about a single PLC block.
In the sec
ond line on the right the selected block is shown, with format “TYPE-NUMBER”. To
select the PLC block, press
ACK/ENTER
, then use ▲▼ buttons to search for the PLC block
wanted (combined with SHIFT allow moving by 10 blocks at a time); confirm by pressing
ACK/ENTER
again.
All parameters of the PLC block selected are shown in the following lines (one line for each
parameter).
•
The first column identifies the type of parameter used (input/output).
•
The second column identifies the resource associated to the parameter. The
resources are normally shown with SICES codification (e.g. the digital input 1 is
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 [6] for SICES codes
description, to identify the PLC resources.
•
The third column shows the current value of the resource. For the digital resources, if
the viewed value is 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).
