English | SNAP-B3000-MODBUS SNAP Analog/Digital Brain, Modicon Modbus Protocol |
  |
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.
