QTP 12 is a complete IP 54 operator panel, specifically designed for industrial use and for direct mounting on automatic machinery. It is, in every respect, video terminals suitable to be the direct interface between operator and machinery in any of the control or comand operations which could be necessary during running or diagnostic of the same. Moreover the availability of interesting additional features make it the right component to solve many applications in the civil, domestic and/or industrial fields, always by keeping an optimum price/performance ratio.

QTP 12 is available with Alphanumeric displays by 20 characters for 2 lines in two different types: LCD type with LED backlite or Fluorescent, or alternatively with Graphic Fluorescent display with 140x16 pixel. In addition on the front panel there are: a 12 Keys membrane keyboard, a personalization label slot (used to carry a name or the user's own logo), and a status LED.

A pratical and robust metallic container, in aluminium shape with the standard DIN 72x144 size allows a direct mounting in front panel modality. A back side openings allows to reach the connectors that can be used for the required wirings. The enclosed brackets supplied with QTP 12 let the user mount and/or unmount the terminal by performing a simple rectangle digging up, on the support panel, that normally is the front side of the electric box.

QTP 12 is really usefull in all those applications where the user must visualize some messages and he must manage not more than 12 Keys. QTP 12 allows, with its EEPROM, the capability to store up to 3371 messages. These messages can be recalled by dedicated commands received through the communication line and visualizated on the display. With this feature the CPU work-time and the program space are optimized, in fact messages must not be sent to the panel every time, they are just stored inside on board EEPROM. Furthermore it is possible to get messages back through the communication line and read them again. So QTP 12 can be used as mass memory where the user can save and read set-up informations, passwords, identification codes, etc. The horizontal Scrolling attribute for the saved messages, let the user display more information on less space: on the first row of the display up to 200 characters can be shown in a self managed sliding modality.

The module's asynchronous serial line can be buffered with the most frequently used electric protocols and thanks to this feature the QTP 12 can be connected to each systems available on the market. Furthermore low cost networks of QTPs can be realized where many different Operator Panel can be contemporaneously managed. Alternatively the terminal can be driven through a synchronous I2C BUS line that allows the connection on local networks, too.
The interconnection with other devices is ensured also by the optional CAN line, that increase the possible applications fields and gives better performance of the cemplete network.

CPU section features 16K FLASH with ISP interface for comfortable programming through the asynchronous serial line. This allows an easy development environment for the user application that doesn't require any additional system, with a considerable cost reductions. The user can write the application program with 8051 compatible code, by using one of the numerous high level development tools as the convenient BASIC compiler BASCOM 8051; the efficient C compiler µC/51 or the well known LadderWORK for the users that want contacts programming. With the scope to simplify much more the development phase, there are different ready to use management Firmwares, that are briefly described below.

grifo® has developed two management firmwares that simplify and speed up the development of user application program on QTP 12. Basically each firmware allows the management of all the hardware resources of the operator panel at high level; in other words the user doesn't have to directly interact on the hardware sections but he must simply use the provided operations. The general features of the firmwares, including possible options, are the following ones:

• Transparent functional modality: the data received by user program, if they are not commands, are directly visualized on display while the key pressed and possible response of the commands are returned to the same program. This modality is normally defined Dumb Terminal.
• Tens of Commands dedicated to visualization and other operations, compatible with ADDS Wiew-Point standard (see details in following table).
• Debouncing, Autorepeat and Keycklick functions for the keys pressed.
• The Code of the pressed key can be changed and moreover the not used keys can be even Disabled.
• Possibility to enable an Autonomous Visualization with different attributes that is automatically shown at Power on.
• Management of LEDs and Buzzer with three different attributes: Enabled, Disabled and Intermittent.
• Management of Brigtness on VFD display in order to obtain always the best visibility in any environmental conditions.
• EEPROMs used for permanent storage of Set-Up, messages, user characters, etc. In base version the EEPROM is 2K Bytes (95 messages) but it can be increased to 66K Bytes (3371 messages), by ordering .EE512 option.
• Memorization on EEPROMs and visualization on display, of maximum 3371 different messages, even with auto scrolling mode.
• The text messages managed by firmwares reduce the user program and thus the communicated data.
• The horizontal auto scrolling attribute for the saved messages, let the user displays more information on less space: on the first row of the display up to 200 characters can be shown in a self managed sliding modality.
• Possibility to save and load data from the on board non volatile memories (backed SRAM and EEPROM).
• Up to 256 different characters defined on display and thus visible.
• 8 User Characters provided of selectable pattern.
• Serial Network connection through I2C BUS synchronous protocol or Master-Slave at 9 bits asynchronous protocol in RS 422, RS 485 and Current Loop.
• Local Set-Up for operating modalities.
• Selectable communication protocol for asynchronous serial line:
  • 1.200, 2.400, 4.800, 9.600, 19.200 or 38.400 Bauds
  • 1 or 2 Stop bit
  • No parity
  • 8 or 9 bits
  • QTP slave address from 00H to FFH with step of 1, for a network of max 256 units
• Selectable communication protocol for I2C BUS:
  • Bit rate from 500 to 15000 bps;
  • Slave mode;
  • Slave Address range from 00H to FEH with step of 2, for a network of max 128 units
• Functionality as serial <-> I2C BUS converter, capable to manage each peripheral devices with this interface (temperature sensors, A/D and D/A converters, etc.).
• Different commands for the Digital output in Open Collector
• Possibility to set and acquire the Real Time Clock and his seven temporal parameter (hour, minutes, seconds, day, month, year and week day).
• The current Date and Time can be autonomously visualized on display, with attributes and positions defined by user.
• Management of a complete Alarm clock that can be set on hour, minutes, seconds, day and month. When the alarm time is reached the digital output is enabled, with a selectable activation endurance time.

Both the firmwares can be comfortably used through their rich list of commands that solve the typical automation problems.

The QTP 12 is able to execute many commands of ADDS View-Point standard and moreover it recognizes and execute numerous other commands, as described in the following table:

Both firmwares, once received the command and the necessary input parameters, perform autonomously the specified operation and at the end they return the possible results established by execution. The firmwares, that are really similar, are different for the user modalities, as below described:

• Serial Firmware ( STANDARD ) The QTP 12 functionality is completely autonomous and the communication occours through the asyncronous serial line (in RS 232, RS 422, RS 485, Current Loop) or the synchronous I2C BUS line, with an external system. The QTP 12 works as a slave unit that receive commands from a Master unit, and it offers both operator interface and manager of his resources, even at a long distance from the same master. The user doesn't change the QTP program but only the Mater unit (PC, PLC, control card, etc.) program. Among the features of this firmware there is a Local Setup that allows manual setting of communication parameters (logic protocol, name, Baud Rate, Stop Bit, etc.) and the management of QTP 12 inside a serial network composed by many different units (up to 256). In addition to the firmware is provided a detailed description of the commands and their use tecniques plus some demo programs for PC and grifo® cards, under source and executable format.
  
• Library Firmware ( OPTIONAL ) In this condition the firmware is linked inside the application program for QTP 12, developed by the user, and it coincides with a list of Library functions directly called by each low and high level development tools. The library functions can be called by all the Console instructions of the selected programming language, as Print, Printf, Kbhit, KeyHit, Input, Getch, Scanf, etc. This choice really simplify the QTP management, reduces the developing time and mantain compatibility with serial firmware. By using this firmware the user must write the application program and he must save, debug and test it directly on QTP 12. Certainly the application program can also use the hardware resources directly, without using the library, whenever it is necessary. In addition to the firmware is provided a detailed description of the commands and their integration tecniques plus some demo programs for the most diffused development tools, under source and executable format.

A list of accessories can be used to speed up and simplify the connection of QTP 12 to the other electronic systems, as described below:

EL 12 The EL 12 module is a complete, low cost, power supply with extremely reduced dimension, that can be used in conjunction with grifo® cards as SDI 02, QTP 12, QTP 16Big, QTP 16, QTP 22, QTP 24, QTP G28, etc.
