11.1 Interface commands
Interface commands allow the device to be remote controlled. Parameters can
be retrieved and the current status can be queried. To do this, the device must
be connected to the master computer via a digital interface. Interface
commands are entered using a terminal program.
Interface commands are divided into IN commands and OUT commands.
• IN commands: Retrieve parameters
Command structure: C
E.g. Retrieve the setpoint temperature:
IN_SP_00
E.g. Response of the device:
55.5
LF
• OUT commands: Set parameters (only in remote control mode)
Command structure: C
+ Parameter
E.g. Set the setpoint temperature to 55.5 °C:
OUT_SP_00
55.5
11.1.1 IN commands
IN commands retrieve device parameters.
