Please note
Transmission of the command is repeated 8 times by the
host. After that the serial connection is regarded as unus
able and is interrupted. Transmission must then be initial
ized again.
B.1.2 CI commands
Caution
Loss of data
The Command Interpreter (CI) contains commands which
reorganise or delete parts of the memory. Existing data are
therefore destroyed:
·
Use preferably the FCT or the control panel for commis
sioning and parametrizing.
·
Use the CI commands only in special applications which
require direct access to the controller.
·
Use CI commands only if you already know their effects
and if they are permitted for your MTR−DCI.
WRITE (W) Write commands (W) transfer a value in the specified format
to the MTR−DCI. As a reply, write commands will be reflected
exactly character by character from the controller of the
MTR−DCI. A checksum <PS> will be inserted in front of the <CR>.
Please note
The following applies when the objects are written:
Discrete values:
A non−permitted value will not be accepted, the previ
ously valid value will be retained.
Concrete values (e.g. lengths, speeds, etc.):
A non−permitted value will be limited up to the next
permitted minimum or maximum value.
