Product Role & System Fit
In industrial automation architectures based on Series 90-70 PLCs, the capacity to expand beyond a single CPU rack is critical for complex control systems. The IC697BEM713 is a Bus Transmitter Module (BTM) that serves precisely that purpose, acting as the bridge between the main PLC rack and multiple expansion racks loaded with I/O and option modules. By enabling communication and power distribution over a dedicated bus line, it allows systems to scale gracefully without sacrificing performance or reliability.
The architecture of a traditional Series 90-70 system centers around a CPU rack, which contains the primary processor and essential I/O modules. When an application requires additional I/O — often the case in manufacturing plants, petrochemical process lines, or large material handling systems — the base rack alone isn’t sufficient. The IC697BEM713 solves this by providing a high-speed parallel interface through which additional racks equipped with Bus Receiver Modules (BRMs) can be connected. Each additional rack effectively becomes an extension of the main system, with coherent data exchange and program distribution across all connected modules.
From a system fit perspective, the IC697BEM713 integrates into most Series 90-70 environments without requiring specialized hardware changes. It occupies a single slot in the main rack — typically anywhere except slot 1 (reserved for the CPU) — and draws power directly from the backplane. Its design supports systems where expanding I/O isn’t optional but foundational to the control strategy, especially in distributed robotics, process automation with extensive sensor networks, and centralized control rooms supporting multiple machine lines.
The integration also extends to software and configuration — while no physical DIP switches are needed for basic expansion, the PLC programming and configuration tools recognize the presence of the Bus Transmitter and automatically account for connected expansion racks. This ensures the PLC logic and I/O mapping remain consistent as the system scales.
