It acts as a Modbus serial slave, not a programmable controller. The module packs 12 digital inputs, 8 digital outputs, two high-speed counters, and two pulse generators into a slim 55 mm housing. Engineers use it to add remote I\/O near machines and cut long field wiring runs. It supports up to seven TM2 expansion modules, so you can scale I\/O without a new rack.\u003c\/p\u003e\n\n\u003ch3\u003e\u003cstrong\u003eSummary\u003c\/strong\u003e\u003c\/h3\u003e\n\n\u003cul\u003e\n  \u003cli\u003eThe \u003cstrong\u003eOTB1S0DM9LP\u003c\/strong\u003e is a bus
