Option missing

What does F36 mean?

An option card is either incorrect, missing, or has incompatible settings for its setpoint source, control signal, or operating mode. This fault indicates a configuration mismatch or hardware absence, leading to an immediate switch-off with inhibit.

• Installation of an unsupported or incorrect type of option card
• Setpoint source, control signal source, or operating mode parameters are incompatible with the installed option card
• Required option card (e.g., FBG11B, FIO12B, FIO21B) is not present
• Front module FIO21B is not supplied with power
