Deterministic Networks and Backplane Bus Velocity

The module establishes high-speed messaging across EtherNet/IP deterministic networks, organizing implicit I/O connections and explicit instruction transfers between host processors and local field devices. Internal power processing circuits convert the 24 VDC primary power feed into a regulated 5 VDC POINTBus supply, driving data frame transfers at maximum backplane bus communication velocity. The integrated POINTBus interface manages bus scanning schedules for up to 63 expansion modules while enforcing current draw thresholds to maintain signal stability. Integrated hardware logic and dual-color LED indicators validate packet timing and status conditions to prevent communication timeouts during continuous control routines.

Frequently Asked Questions

Q: How does the internal 5 VDC power bus limit the maximum number of connected expansion modules?

A: The integrated power supply delivers up to 1.0 A at 5 VDC to the POINTBus backplane. If the cumulative current draw of connected modules exceeds 1.0 A, field engineers must install a 1734-FPD expansion power distribution module before adding more cards.

Q: How can network addresses be configured directly on the module hardware?

A: Three integrated thumbwheel switches allow manual assignment of the last octet in a static IP address (192.168.1.xxx) without software, while standard BOOTP or DHCP server protocols handle dynamic addressing.

Field Installation Guidelines

Mount the module onto a grounded 35 mm DIN rail inside an IP54-rated industrial enclosure. Press the unit firmly onto the rail until the locking latch engages, then slide adjacent 1734 POINT I/O modules along the backplane interface to complete the physical bus assembly.

Connect CAT5e or CAT6 industrial shielded Ethernet cabling to the front RJ45 port, maintaining separation from high-voltage motor wires and AC power lines to limit electromagnetic interference. Bond the DIN rail directly to the primary enclosure ground bar using a short, low-impedance copper conductor.

What's clients say about us

Excellent Emergency Support!

Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
