FAQ
Frequently Asked Questions (FAQ)
Q1: What is the maximum number of I/O channels available on the 07DC91 module?
A1: The module provides a total of 32 channels—16 digital inputs, 8 digital outputs, and 8 configurable channels that can function as either inputs or outputs.
Q2: How is the address for the module set?
A2: Addressing is done using the DIL coding switch located under the slide cover on the right side of the housing. The address is read only during initialization.
Q3: Are the outputs protected against short circuits and overloads?
A3: Yes, each output is protected against short circuits and overloads. When the current exceeds 0.7 A, protection is triggered and the output attempts automatic reactivation.
Q4: What type of diagnostic features are available on this module?
A4: The module supports detection of output short-circuits, overloads, internal errors, and CS31 system bus failures. These errors are indicated via LEDs and transmitted to the central controller.
Q5: How are the configurable channels used?
A5: The 8 configurable channels can be set by the user program as inputs, outputs, or re-readable outputs. Their behavior depends on how they are accessed in the user logic.
Q6: What is the method for visualizing channel status?
A6: Each input channel is indicated by a green LED, while each output or configurable channel uses a yellow LED. A red LED indicates module error conditions.
Q7: What is the recommended installation position?
A7: The module should be installed vertically, with connectors facing up and down. Ensure proper ventilation to allow natural convection cooling.
Q8: Can the module be used in high-frequency switching applications?
A8: The maximum switching frequency is 0.5 Hz for inductive loads and up to 11 Hz for lamps (at max 5 W). For higher frequency switching, consider using relay or solid-state interfaces.
