7.1 Introduction
This chapter will introduce some concepts and describes some operations of the product. These contents are partly related and implemented in firmware. This software implements all features that allow the product to be a component of the system programmable Qmove.
7.2 Organizing data and memories
To best understand the terms used in this chapter, it is important to know the organisation of data and memory in a QMOVE application. QMOVE applications are programs written in QCL language that, translated in binary code, are transferred onto QMOVE hardware and saved there. In the hardware, the microprocessor runs has a program called firmware that interprets the above binary code instructions and performs the operations associated to them.
A QCL application, in addition to the instructions, is also composed of variables that the QCL instructions act on.. Some of these variables are retentive, i.e. their values remain unaltered from shut-off to start up. The flow chart below illustrates the organisation of data in a QCL application transferred to the memory of any QMOVE hardware:
It can be noted that, the QMOVE hardware has several mass storage devices:
“Flash memory”, where the following is saved:
-
QCL program: the series of QCL instructions translated into binary by the compiler.
-
HMI program: the series of HMI screens translated into binary by the compiler. This program only exists when the QMOVE hardware has a display.
-
Configuration data: the calibration and configuration data, the touch-screen calibration settings, the ethernet communication configuration data (IP address, etc…), etc.
“Non volatile memory”, which stores:
-
Retentive variables: the group of variables that remains unaltered on a shut-off and startup (e.g. SYSTEM, ARRAYS, DATAGROUP, etc).
“Volatile memory”, which stores:
-
Not retentive variables: the group of variables that is set to 0 at each startup (e.g. GLOBAL, ARRGBL, etc).
The volatile data memory is also used as dynamic memory. i.e. the memory used by the firmware for internal operations and active HMI screen management.
“Mass storage internal device” is managed by a standard filesystem and is useful to save information by the DATASTORE device (read - write binary or csv files with recipes, logs, variuous setups, etc).
It 'also used to store the backup of the application QMOVE and other service files.“Mass storage external device” is managed by a standard filesystem and is useful for loading the QMOVE application, data loading/saving, firmware update or to save informations by the DATASTORE device.
7.3 SETUP PAGE
ATTENZIONE: WARNING: The use of these procedures is potentially dangerous (see for example the application delete) and it is preferable that is carried out by a specialist supervision. The system functions are special procedures that allow the user to perform various operations such as setting/calibration of devices, saving/restoring data and application on/from removable devices, deleting the application and management of storage devices.
To access the new system functions simply login to instrument SETUP.Note: If there is no Terminal application software will automatically enter in SETUP.
7.3.1 Procedure
To access in the System functions, press the BOOT key or press together the keys “F2 + F4 + F6”.
BOOTThe following menu appears:
To select a function using the vertical arrows of the virtual keyboard, then press Enter for view the selected function. The system restarts and displays the system function selected.

Reports the status of the serial communication. If everything is OK the message:
Ok
If the ‘COM’ led is ON and the'STATE' led flashing, the connection between the HMI and the QMOVE is not active. The reasons can be:Checksum wrong Appears the ‘No match’ message, which means that the application built for the Terminal is not compatible with the QMOVE software and then the communication is not established because it may create incompatibilities in data of the system. The ‘No match’ condition excludes communication problems due to connection errors or problems related to serial ports.
Communication interrupted Appears the ‘Time Out’ message, which means that the terminal not received response or the response has not been received completely. If the ‘COM’ led is ON it probably means there is a malfunction of one of the two devices (QMOVE or HMI) or connection between the device. If the 'COM' led is OFF means that at least one ‘Time Out’ occured from the power ON (example an electrical noise).
Reading errors Appears the ‘Read Error’ message, which means that the the response string to a reading didn't the correct syntax of the Protocol. This can happen if the Terminal makes a request of a variable with index out of range. For example the read request of an element of an array, where the value of i is greater than the size of the array itself; if i is a constant value that the compiler of the application can inspect and report the error, but if i is the value that is contained in a variable can take place such an error.
Writing errors Appears the ‘Write Error’ message, which means that the response string to a reading didn't the correct syntax laid down in the Protocol. All that has been described for the readings also applies to torn writes
Backup error Appears the ‘Backup Error’ message, which means that the QMOVE application data backup operation is not successful.
Restore error Appears the ‘Restore Error’ message, which means that the restore operation of data of the QMOVE application is not successful.

7.4 Informazioni per la programmazione
In questo capitolo sono raccolte tutte le informazioni relative al prodotto necessarie durante la programmazione, ovvero durante lo sviluppo di un applicativo QCL.
7.4.1 Ambienti di sviluppo
Per la programmazione del prodotto è necessario utilizzare gli ambienti Qview-5 per la programmazione del codice QCL e se il prodotto è equipaggiato di display grafico, anche l'ambiente Qpaint-5 per la progettazione delle pagine grafiche. Ambedue questi software sono contenuti in un pacchetto software che si chiama Qworkbench e che è liberamente scaricabile dal sito Qem (nella sezione download).
Per programmare con l'ambiente di sviluppo QPaint-5 è importante selezionare correttamente il target. All'interno dell'ambiente selezionare Progetto → Configurazione del Target quindi selezionare in accordo con il codice di ordinazione.
In questo paragrafo vedremo come è possibile rilevare una stima dell'utilizzo delle memorie nel prodotto. La memoria non volatile, disponibile per memorizzare il programma QCL, ha una capacità di 512KB.
La quantità di memoria occupata è pari alla dimensione del file .BIN generato dal Qview. La percentuale di memoria occupata è visualizzabile nel pannello CPU del Qview, alla voce “Used CODE memory”, oppure è possibile ottenere questa informazione dal valore del parametro “sizeapp” del device QMOS.La memoria non volatile, disponibile per memorizzare il programma HMI ha una capacità 5.5MB.
La quantità di memoria occupata è pari alla dimensione del file .BIN generato da Qpaint, il cui valore (in bytes) è visualizzato nel parametro “memqtp” del device MMIQ2.La memoria dati non volatile, disponibile per memorizzare le variabili ritentive, ha una capacità di 819KB.
La percentuale di memoria occupata è visualizzabile nel pannello CPU del Qview, alla voce “Used RETENTIVE”, oppure è possibile ottenere questa informazione dal valore del parametro “sizeret” del device QMOS.La memoria dati volatile per memorizzare le variabili non ritentive ha una capacità dipendente da vari fattori (per esempio la dimensione dei programmi HMI e QCL, della pagina HMI in visualizzazione ecc.)
La memoria generale del sistema libera, disponibile come memoria dati volatile, è indicata dal parametro “memfree” nel device MMIQ2.8. Accessori disponibili
