Technical Specifications Applicable PLC: GE Series‑90 PLC Bus Interface: Dual independent Genius bus channels Hardware Version: H Operating Temperature Range: 0 ℃ to +60 ℃ Storage Temperature Range: ‑40 ℃ to +85 ℃ Mounting: PLC rack slot‑mount
Functional Features Dual Genius bus master channel operation. Each bus channel can run separate Genius I/O network. Independent bus diagnosis for each channel. Off‑load Genius protocol processing from main PLC CPU. Front‑panel LED status for each bus channel.
Application Scenarios Factory dual‑segment Genius I/O network, redundant Genius bus architecture, large‑scale distributed automation control system, power plant auxiliary control spare‑parts.
Performance Parameters Each channel maximum bus speed: 1.5 Mbps Each channel supports maximum node quantity: Comply with GE Genius specification.
Structural Characteristics Rack‑mount PCB module. Two Genius bus field connectors. Dual‑group LED indicators for channel A and channel B. Gold‑plated backplane connector interfacing with PLC rack bus.
Working Principle Two on‑board independent coprocessor circuits manage respective Genius bus channel. Data from two separate Genius networks are exchanged with PLC CPU memory via rack backplane bus. Each channel executes protocol, polling and fault monitoring separately.
Installation Requirements Insert into Series‑90 PLC assigned rack slot. Wire two Genius bus networks respectively. Set termination resistor for each bus segment endpoints. Complete hardware configuration in programming software.
Usage Notes Do not mix devices from two different bus segments. Each Genius network needs its own proper termination setting. Power off rack power supply before module replacement.
