B.2.2 CI commands
Caution
Loss of data.
The Command Interpreter (CI) contains commands which
reorganise or delete parts of the memory. Existing data is
destroyed in this process:
• It is preferable to use the FCT or the control panel for
commissioning and parameterising.
• Use the CI commands only in special cases 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 response, write commands will be re-
flected back exactly character by character from the MTR-DCI.
A checksum <PS> will be inserted in front of the <CR>.
READ (R) Read commands (R) transfer a value from the MTR-DCI. The
response contains the value read. A checksum <PS> will be
inserted in front of the <CR>.
All commands are entered as a character sequence without
any empty spaces. A hex character is a “char” character in
hex format.
