The LOGO! status change is attempted up to three times, if necessary. If still no
reply is received from LOGO!, an SMS containing the text “NO SUCCESS” will be
transmitted instead of “OK”
If LOGO! acknowledges the status change negatively, “ERROR” is sent as the reply
SMS. This can also occur if the current LOGO! status already matches the status to
be set.
A callback number (“CN: “) does not have to be specified. However, without a
callback number, there is no reply.

3.3.5 LOGO! Checksum
Command:
CHKSUM?
A reply follows containing the checksum of the control program running on the
LOGO!
The checksum output is made up of four hexadecimal digits.
This function can be used to uniquely identify a control program (version control).
When an elapsed time counter is used, the checksum is changed when the “Reset
All” (Ral) input of the counter is activated the first time. Afterwards, the checksum
is not changed. In this case, the checksum of the control program must be read
out again.
The LOGO! checksum scan is attempted up to three times, if necessary. If still no
reply is received from LOGO!, an SMS containing the text “NO SUCCESS” will be
transmitted instead of the checksum SMS.
A callback number (“CN: “) must be specified.
