PasswordString = "Password"
PasswordNumber = 0
CXServer.Protect "PLC1", EnableProtection,
PasswordString, PasswordNumber
Example 2 (unsets protection for C series PLC)
Dim SetProtection
Dim PasswordString
Dim PasswordNumber
EnableProtection = false
PasswordString = ""
PasswordNumber = 12345678
CXServer.Protect "PLC1", EnableProtection,
PasswordString, PasswordNumber
The parameters of this command are, in order:
• PLC - Name of PLC.
• EnableProtection - true to set password protection, false to unset it
• PasswordString - Password as a string. For CS series PLCs this should
be a string of up to 8 characters. For CV PLCs this should be a string of
up to 8 characters containing a hexadecimal number, e.g. "12345678". For
C series PLCs this should be a string of up to 4 characters containing a
hexadecimal number, e.g. "1234".
• PasswordNumber - currently this is only used for C and CV series PLCs,
and only when the password string is empty. In those circumstances it is
simply a number representing the value of the 4 or 8 digit password.
Please note that the password is entered in CX-Programmer as a
hexadecimal string (as with the PasswordString parameter above), and
that, for example, the value 1234 in decimal is the equivalent to "04d2" as
a hexadecimal password string.
Additional C Series PLC notes: For C series the PLC program needs code (the
first line of the application) in the PLC to enable password setting/release, and
this fixes the password value.
e.g. LD AR10.01
FUN49 0 0 #1234 (#1234 - password value in Hex)
When setting the password this value is used rather than the value passed -
i.e. the password string or number is ignored. The correct password must be
provided, however, when disabling the password protection.
B.30 LastErrorString
This property, which can be set as well as read, is a textual description of the
last error that occurred. If none have occurred, it is blank.
Example:
txtError = CXServer.LastErrorString
CXServer.LastErrorString = ""
