Note Disconnection detection (82) operates for input numbers used with a range of 1
to 5 V (4 to 20 mA).
Errors indicated with 8j codes are automatically reset when proper counter-
measures are taken. The errors indicated with Fj codes are cleared when the
power is turned on after making the correct settings and when the Special I/O
Unit Restart Bit is turned OFF, ON, and OFF again.
When the CPU Unit detects an error at a Special I/O Unit, it outputs to the CPU
Unit's SR and AR areas as shown below.

up the PC again, and the second way is to turn the Special I/O Unit Restart Bit
ON and then OFF again.
