Industrial Application Scenarios
TheDLM01link interface module is typically deployed within the primary processor subracks of legacy chemical batch plants, automated assembly lines, water treatment facilities, and pharmaceutical mixing skids running on older ABB Freelance topologies. Within these frameworks, isolated process nodes must pool their sensory inputs and actuator statuses to ensure systemic interlocks remain coordinated. TheDLM01acts as the dedicated network link that spans these internal bus boundaries, ensuring that critical safety overrides and closed-loop speed parameters propagate down the backplane lines instantly without creating protocol communication traffic jams.
