Other Characteristics

No Diagnostics During Configuration
During configuration (CP online), diagnostics of the CP 443-5 Basic over MPI is not
permitted.
Memory Reset of the CP
Warning
!
Please note that when you reset the CP memory using NCM Diagnostics or the
SIMATIC Manager, the configuration data on the CPU must also be deleted
otherwise the data will become inconsistent.
When using the S7-400H, do not use the memory reset function on the CP!
FMS Operation – Disabling and Enabling Interrupts and Asynchronous Events
Communication using the FMS blocks in the user program can break down if
interrupts take too long to service (interrupt-driven programs such as hardware and
diagnostic interrupts). You should check the codes in the CP diagnostic buffer.
It is advisable to disable interrupts before calling the FMS blocks and to enable
them again after the FMS block call.
