Profinet and Deterministic Network Processing
The internal dual-connector architecture and differential communication links execute high-speed data exchanges between primary and backup central processing units to maintain synchronized state tracking. Backplane bus communication velocity parameters allow seamless telegram processing without introducing jitter into redundant control loops. Hardware-level monitoring circuits continuously track differential signal integrity across inter-CPU cabling to detect communication drops instantly during runtime operations.
Frequently Asked Questions
Q: Does this module support live hot-swapping within an active Series 90-70 rack?
A: Hot-plugging operations are restricted; system power must be isolated from the rack baseplate prior to inserting or extracting the module to avoid backplane bus faults.
Q: What is the maximum allowable physical distance between redundant CPU racks connected by this module?
A: The maximum supported cable length for the differential communication link is 15 meters.
Q: How is operational status visually diagnosed on the physical frontplate?
A: The module is equipped with integrated LED indicators alongside a diagnostic pushbutton for local state verification.
Field Installation Guidelines
- Ensure that all local rack power supplies are completely shut down before installing or removing the module from its designated single slot.
- Secure the module retention screws firmly to guarantee proper mating with backplane connectors and maintain VME bus ground continuity.
- Route inter-CPU communication cables through dedicated shielded conduits away from high-voltage power lines and motor starter circuits to prevent differential signal interference.
