Note
Unforcing the I/O points does not place them in the OFF state. Unforcing only
removes force. The points remain in their last state until you manually change
them or they are changed by the program.
!
Caution
A fatal error can occur in the S7-200 CPU if power is removed before the force
information is written to the EEPROM of the CPU.
Such a failure could result in the CPU going into fatal error mode upon next
power-up.
To clear the fatal error, rewrite the force information to the CPU or unforce all I/O
points, then power cycle the CPU to clear the fatal error.
