B.4 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 only CI commands if you already know their effects
and if they are permitted for your SFC−DC.
WRITE (W) Write commands (W) transfer a value in the specified format
to the SFC−DC. As a reply, write commands will be reflected
exactly character by character from the controller of the
SFC−DC. A checksum <PS> will be inserted in front of the <CR>.
READ (R) Read commands (R) transfer a value from the SFC−DC. The
reply from the SFC−DC controller contains the value read. A
checksum <PS> will be inserted in front of the <CR>.
All commands will be entered as a character sequence with
out empty spaces. A hex character corresponds to a Char
character in hex format.
