9. Remote control

9.1. Communication with a PC or a superordinated data system

Suitable terminal programs for communicating with a PC are:

 MS-Windows - TERMINAL.EXE (included with MS-Windows).

If the controller is put into remote control mode via the configuration

level, the display will read "r OFF" = REMOTE STOP. The controller is

now operated via the computer.

In general, the computer (master) sends commands to the controller

(slave). The controller sends data (including error messages) only

when the computer asks for it.

A transfer sequence consists of:

 Command

 space (; Hex: 20)

 parameter (the character separating decimals in a

 group is the period) End of file (; Hex: 0D)

The commands are divided into in and out commands.

in commands: asking for parameters to be displayed

out commands: setting parameters

The out commands are valid only in remote control mode.

Examples:

 Command to set the working temperature to 55.5 °C:

out_sp_00 55.5

 Command to ask for the working temperature:

in_sp_00

 Response from the controller:

55.5
