Table 6- 11 Status displays at the digital outputs of CP52M0
DA01 to 11 Indicate the CP52IO slot (slots 2-12) from which the operating state of the
four fiber-optic interfaces is displayed on DA12-DA15. The operating state
display of the individual CP52IO modules is cycled at seconds intervals.
DA12 to 15 Indicate the operating state of the four fiber-optic interfaces of a CP52IO
(DA12 fiber-optic interface 1, DA13 fiber-optic interface 2, etc.).
• Logical status "1" => FOC interface is OK
• Logical status "0" => Error at FOC interface, or CP52IO is missing
