20.2 Diagnostic tables for check I/O
The clear text from the following tables cannot be configured, but is required for a
function as well as determining if inputs or outputs are occupied in duplicate.
1rst notconf IO Pos = 82 => Input external control 2 is not assigned an input
(Nusd).
Caution: The plant is locked against switch on!
Doubled config I/O = Yes
Doubled config I/Os = 82 81
Doubled conf I/O pos = DI3
Inputs External contrl 1 and 2 were assigned the same output DI3.
