Interface modules (RS232/SERIAL, Com.G@te and Web.G@te) and Interface menus General information: Peter Huber Kältemaschinenbau GmbH offers several possibilities of external analogue and digital control. The interactive and modular Plug&Play interface technology makes it possible to retrofit interfaces (see possibilities below) even for the smallest CC temperature control units. Due to space constraints the implementation of an internal Com.G@te and external Web.G@te is not possible for the immersion thermostat CC-E and combinations using the immersion thermostat CC-E. Instead of an internal Gate there exists the possibility to connect via an interface cable an external Gate which is then directly connected to the CC temperature control unit. Every basic CC temperature control unit is equipped with a serial interface RS232 and enabling communication with a PC. The following software protocols/commands are available: The PP-command set enables an easy and fast control of a PC or laptop via the COM interface. The PP-commands can also be used for communication via a serial bus interface RS485 (via a Com.G@te). Only one temperature control unit can be controlled. The LAI-command set has to be used if more than one temperature control unit is to be controlled via the serial bus interface RS485 This enables a software related control via the device address (the device address has to be set accordingly on the machine). An advantage of the LAI-command is that with one command only, several parameters can be interrogated. Besides the main commands a Namur-command can be used for serial data transference. Some examples of individual commands are listed below: The full list of commands on all software protocols can be found in the handbook Data Communication. It can be downloaded from our website only. � PP-Command Set Request internal temperature TI?\r\n Respond temperature control unit e.g.: +00400 T 4°C or -00400 at -4°C Request external (process) temperature TE?\r\n Respond temperature control unit: +00400 at 4°C or -00400 at -4°C Setting the set-point with echo: SP@02000\r\n Respond temperature control unit: SP +02000\r\n Switching on the temperature control unit: CA@ 1\r\n Switching off the temperature control unit: CA@ 0\r\n Temperature control mode process: TM@ 1\r\n Temperature control mode internal TM@ 0\r\n \r\n = end character Carriage Return and Line Feed 69
