Industrial Control and Network Communication
The IC698BEM711 communicates with Genius Bus devices through the RX7i PLC rack. The controller performs bus scanning and exchanges I/O data with connected Genius-compatible nodes.
Communication speed depends on the configured Genius Bus network. Therefore, the selected rate must match the network design and associated cable characteristics. The module also provides diagnostic information for bus status and connected device conditions.
Because the module uses the RX7i VME backplane, the rack supplies its operating power and provides the internal PLC interface. The installation should therefore preserve the specified rack position and backplane connection.
Frequently Asked Questions
Q: Does the IC698BEM711 connect directly to the RX7i backplane?
A: Yes. The module installs in an RX7i VME-based rack and receives power through the rack backplane.
Q: How many Genius Bus devices can the IC698BEM711 support?
A: The supplied specifications identify support for up to 31 devices on a Genius Bus network.
Q: Can the Genius Bus communication rate be configured?
A: Yes. The supplied information identifies selectable rates of 37.5 Kbaud, 57.6 Kbaud, 76.8 Kbaud, and 153.6 Kbaud.
Field Installation Guidelines
Install the IC698BEM711 in the designated RX7i VME rack position with the backplane connector fully engaged. Before installation or removal, follow the rack manufacturer’s power and module-handling procedures.
Route Genius Bus cabling separately from high-voltage power conductors and high-current switching circuits where practical. Maintain appropriate cable shielding and grounding practices for the installed Genius Bus network. Also verify connector seating and cable termination before energizing the rack.
Finally, confirm that the selected Genius Bus communication rate matches the connected network configuration. After startup, use the available PLC diagnostics to verify bus communication and identify node or network faults.
