If a PLC signal is injected at the PLC connection point "CTF_BLOCK", the operation of
the CTF function is blocked. The user can program to inject an external signal for the failure
detection using the PLC connection point EXTERNAL_CTF; the CTF_DETECT signal is
generated when the signal is injected at the EXTERNAL_CTF.
