n
Set “Enable debug” param-
eter to
“OFF”
on SM560-S
n
Create boot projects for
SM560-S and PM5xx
n
Execute powering off/on
n
Go to CoDeSys Safety and
compare boot project CRCs
on your PC and SM560-S.
The comparison shows that
they are the same, which is
OK.
n
Try to create a boot project
for SM560-S. An error mes-
sage follows because of
“Enable debug” set to
“OFF”
for SM560-S, which
is OK.
n
Repeat the comparison of
boot project CRCs on your
PC and SM560-S. They are
reported to be not equal
now (boot project CRC for
SM560-S is shown as
CDCDCDCD), which can
be misleading since the
boot project on SM560-S
was not changed.
CoDeSys Safety does not sup-
port the described use case.
After powering off/on of SM560-
S Safety CPU, the correct boot
project CRC shall be shown for
SM560-S.
12.
The serial driver is used to con-
nect to SM560-S Safety CPU.
One executes
“Login”
com-
mand shortly followed by
“Logout”
command in CoD-
eSys Safety and shortly after
this the
“Login”
command is
again executed. After second
login attempt, the communica-
tion error is shown in CoDeSys
Safety.
The serial driver does not have
enough time to be re-initialized.
Wait for at least 20 seconds
before executing
“Login”
com-
mand after
“Logout”
was per-
formed.
