OPTO 22 – SNAP-B3000-MODBUS _ SNAP Analog/Digital Brain, Modicon Modbus Protocol
Quick Specs:
- SNAP Analog/Digital Brain
- Modicon Modbus Protocol
The SNAP-B3000-MODBUS brain is a high-performance processor designed to remotely control and acquire a mix of SNAP analog and digital I/O modules on a B-series rack.
The brain communicates to any Modbus master device via RS-485 using the Modbus slave protocol in both ASCII and RTU modes. Brain functions include latching, counting, on/off status, and thermocouple linearization.
NOTE: Not all SNAP I/O modules are compatible with this brain. See Legacy and Current Product Comparison and Compatibility Charts to determine compatibility.
