Profinet / EtherNet/IP Deterministic Networks and Bus Bridging
The physical design of the hardware sub-assembly interfaces directly with the right-hand terminal interface of the HN800 device series. It preserves high backplane bus communication velocity across segmented racks without introducing data skew or signal attenuation. This extension routing mechanism ensures that downstream modules maintain absolute firmware flash compatibility with the central processor, supporting seamless communication cycles over Profinet / EtherNet/IP deterministic networks while keeping propagation latencies within nominal microsecond tolerances.
Frequently Asked Questions
Q: Does the bus extender support live hot-swap insertion on an active HN800 backplane rack?
A: No. To prevent signal line glitches, impedance mismatches, or power drops along the extended backplane bus segment, the HN800 rack assembly must be powered down before executing mechanical connection.
Q: How does this module affect the I/O density scaling of the primary control node?
A: The CHBX01R functions as a physical and electrical bridge to allow horizontal row expansion. It does not possess independent registers and does not reduce or restrict the master controller's capacity for I/O density scaling.
Q: What are the grounding requirements for the extended backplane bus row?
A: The chassis ground is established through the primary rail mounting hooks. The extended device row must share a common ground reference with the host HN800 master rack to suppress common-mode electrical noise.
Field Installation Guidelines
-
Orientation and Position: Install the module exclusively on the far right end of the HN800 device row. Ensure the interlocking bus contacts are fully aligned horizontally before execution.
-
DIN Rail Fastening: Snap the unit securely onto a standard grounded 35 mm DIN rail. Verify that the mechanical locking clip locks into position to counter continuous industrial vibration.
-
Cable Routing Restrictions: Keep external communication links and low-voltage field loop cabling isolated from heavy power generation lines to prevent induced electromagnetic noise on the extended parallel bus traces.
-
Thermal and Physical Clearances: Observe the standard vertical clearance boundaries above and below the 127 mm height profile to facilitate proper convective heat dissipation through the module row.
