Note If a Unit with the blown-fuse detection function and alarm detection circuit
(C200H-OD411/213/214/OA221) is used on a C200H Slave Rack that is con-
nected to a PC other than a C200H/C200HS, all 16 I/O points will be regarded as
outputs. Therefore, you will not be able to read the flags for blown-fuse detection
function and alarm detection circuit from the ladder program.
