Backplane Communication and I/O Density Scaling
The NP1BS-11 serves as the central hardware platform for module installation and internal bus communication. The chassis architecture provides dedicated processor bus resources and supports multiple CPU configurations within a common control system.
With eleven physical slots and support for up to nine functional modules in addition to the power supply position, the chassis allows expansion of local I/O, communication interfaces, and processor resources while maintaining a unified backplane structure.
Frequently Asked Questions
Q: How many modules can be installed on the NP1BS-11?
A: The chassis provides 11 total slots and supports up to 9 functional modules, excluding the power supply module.
Q: Does the chassis support multiple CPUs?
A: Yes. The supplied specifications identify three processor bus slots for multi-CPU system configurations.
Q: Is the NP1BS-11 an active control module?
A: No. The unit functions as a base board chassis that distributes power and backplane communication to installed modules.
Field Installation Guidelines
-
Install the chassis on a rigid mounting surface inside a control cabinet.
-
Mount the power supply module in the designated left-side position.
-
Verify slot assignments before inserting CPU and I/O modules.
-
Ensure all modules are fully engaged with the backplane connectors.
-
Route communication and I/O wiring separately from power wiring.
-
Confirm chassis grounding before applying system power.
