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