4.4.2 Format – Command – Feedback
Control commands are defined with the command, (when indicated)
parameters and (optional) the unit address attached with underscore.
There are 4 kinds of addressing:
1. Without any address, addressing one unit, feedback- see spreadsheet 2
2. Basic address with letter A to Y: _C, only one unit, feedback- see
spreadsheet 2
3. Range address with letter A to Y: _AK, only one unit, feedback- see
spreadsheet 2
4. Command to ALL connected units: _Z, feedback = command
Feedback of commands
The feedback of the addressed units is as follows:
1. OK or ER [code of error] – in the case of error
2. Command and parameter (when indicated)
3. Unit address (A-Y, Z = all units, default address is: A)
If a command is addressed with _Z or no unit is addressed, then the
feedback will be identical to the command.
Error codes
Error 1: Unknown Command
Error 2: Manual Mode (Start, Stop not possible)
Error 3: Parameter out of range (set value not allowed)
4.4.3 Hints to Parameter Operation
The control unit is saving two different sets of parameters independently –
in each case for manual and remote operation.
By starting the control unit manually (by using the keys) or remotely (by
using the RS232 interface) the control unit will be started in the manual or
remote mode. It is NOT possible to switch from the manual to the remote
mode or backwards. Furthermore it can be changed only the parameters
of the actual running mode.
The mode can be changed by switching off the control unit by pressing the
ON/OFF-key (11).
The Set -commands can only set the parameters of the remote mode.
The Send -commands are giving always back the parameters of the
actual running mode.
The manual parameters can be changed only by the keys during
running in the manual mode and the remote parameter only by the
RS232 interface during running in the remote mode!
