The UNIGATE® IC Deutschmann Automation GmbH & Co. KG The UNIGATE® IC Technical introduction The UNIGATE® IC by Deutschmann Automation contains all components that are required for the communication in a fieldbus in one single module. Therefore a developer does not have to take care for that detail any more, only a hardware redesign is necessary in order to integrate the UNIGATE®...

Page 11: Boot Enable
Deutschmann Automation GmbH & Co. KG Hardware design 3.2.1 -Boot enable The IC is started in the firmware update mode with the level GND during the power up process. See also chapter 10 on page 26. 3.2.2 Load out Strobe signal for the synchronous serial interface. With the positive edge at this output data is taken from the connected shift registers to the physical outputs.
Page 12: Software
Hardware design Deutschmann Automation GmbH & Co. KG Software The software executes script-commands, which in turn control the IC’s hardware and they pro- cess their complete protocol by software. The script itself can be generated by the company Deutschmann Automation or with the software Protocol Developer by yourself. For a detailed description of the script.commands of the Protocol Developer see the instruction manual Proto- col Developer and the online documentation concerning script-commands.
Page 13 Deutschmann Automation GmbH & Co. KG Hardware design Version 1: Use as a pure link module for the bus The UNIGATE® IC independently processes the communication with the customer’s device via the TTL-interface. Version 2: Use of UNIGATE® IC for digital or analog I/O-modules Here only the synchronous serial interface is used, the asynchronous serial interface is basically of no account.
Page 14 Hardware design Deutschmann Automation GmbH & Co. KG The following circuit diagram is an example for how shift register components can be connected to the IC. Version 3: Example for digital I/Os The serial synchronous and the asynchronous interface as well can be operated by UNIGATE® IC at the same time.

Page 17: The Serial Interface
Deutschmann Automation GmbH & Co. KG The serial interface The serial interface Overview The serial interface is an important connection between the UNIGATE® IC and the micro control- ler of your application. The interface is designed in a way so that your application at least does not have to be changed on the software-side.
Page 18: Synchronous Interface
Synchronous interface Deutschmann Automation GmbH & Co. KG Synchronous interface Overview of the synchronous serial interface The synchronous serial interface is an interface of the IC to clocked shift registers. About this it is not only possible to input or output digital signals but also the addressing of DA- or AD-convert- ers with clocked serial interface is possible as well as the connection of LEDs or reading in rotary switches.
Page 19: The Debug-Interface
Deutschmann Automation GmbH & Co. KG The Debug-interface The Debug-interface Overview of the Debug-interface The UNIGATE® IC features a Debug-interface, that allows a step-by-step processing of a script. Normally this interface is only required for the development of a script. Starting in the Debug-mode When applying power to the UNIGATE®...
Page 20: Script And Configuration
Script and configuration Deutschmann Automation GmbH & Co. KG Script and configuration Overview In the configuration mode the scripts and configurations, stored in the UNIGATE® IC, can be replaced or updated via the serial interface. The configuration mode If the pin „ConfigMode“ pulled to GND during the PowerUp or Reset, then the UNIGATE® IC starts in the configuration mode.
Page 21: Generating A Script
Deutschmann Automation GmbH & Co. KG Generating a script Generating a script What is a script? A script is a sequence of commands, that are executed in that exact order. Because of the fact that also mechanisms are given that control the program flow in the script it is also possible to assemble more complex processes from these simple commands.
Page 22: The Use Of The Protocol Developer
Generating a script Deutschmann Automation GmbH & Co. KG The use of the Protocol Developer The Protocol Developer is a tool for an easy generation of a script for our script gateways. Its operation is exactly aimed at this use. After starting the program the script that was loaded the last time is loaded again, provided that it is not the first start.
Page 23: Script Processing Times
Deutschmann Automation GmbH & Co. KG Generating a script 4800 baud: 0.16% 9600 baud: 0.16% 19200 baud: 0.16% 38400 baud: 1.35% 57600 baud: 1.35% 62500 baud: 115200 baud: 1.35% 312500 baud: 625000 baud: Script processing times The Script is translated by the Protocol Developer and the consequently generated code is loaded into the Gateway.

DeviceNet Deutschmann Automation GmbH & Co. KG DeviceNet At present UNIGATE® IC-DeviceNet supports the data exchange in the mode “polling“. The other possible modes “bit-strobe“ and “change of state“ are in preparation. In the mode “polling“ the UNIGATE® IC is at present restricted to up to 255 bytes input and output. Every combination of input- and output-size is possible.

Page 29: 12 Accessory
Deutschmann Automation GmbH & Co. KG Accessory 12 Accessory The following tools are available from Deutschmann Automation. 12.1 Development board The development board (also called basis board) is a circuit board on which the UNIGATE® IC can be installed. The IC is installed in the ZIF-socket. The ZIF-socket allows an easy insertion and remove of the IC.
Page 30: Quick Start
Accessory Deutschmann Automation GmbH & Co. KG The basis board contains a socket to put on the IC, all RS- and fieldbus-sided connectors, switches and LEDs. Actually you cannot tell the difference to a ’normal’ UNIGATE® any more. With the basis board your UNIGATE® IC can be connected to your product within a few minutes, in order to prepare the implementation then.
