Industrial gateway RESI-xS0 series

communicationtelemetryModbus

Overview
You want to integrate meters with S0 pulse outputs? The RESI-1S0-xxx and RESI-2S0-xxx gateway family is designed for this purpose. RESI-1S0-xxx counts impulses from one S0 meter; RESI-2S0-xxx counts impulses from two S0 meters. Measured counts are periodically saved to ferromagnetic RAM (FRAM) to restore values after power loss. Each counter supports a configurable multiplication factor to convert pulses into engineering units (e.g. kWh, liters, m³). Built-in software filtering reduces false counts caused by electrical noise on reed contacts or cabling.

Communication options / Variants

• RESI-1S0-SIO: Gateway, 1x S0 input, MODBUS/RTU + ASCII, 1x RS232 + 1x RS485 (gateway for one meter)
• RESI-2S0-SIO: Gateway, 2x S0 inputs, MODBUS/RTU + ASCII, 1x RS232 + 1x RS485 (gateway for two meters)
• RESI-1S0-ETH: Gateway, 1x S0 input, MODBUS/TCP + ASCII, 1x Ethernet (gateway for one meter)
• RESI-2S0-ETH: Gateway, 2x S0 inputs, MODBUS/TCP + ASCII, 1x Ethernet (gateway for two meters)

Intended connections
Gateways are intended for connection to controllers and HMIs such as PCs, PLCs, DDCs, media controllers, industrial minicomputers, Raspberry Pi, Arduino or dedicated hardware.

Configuration / Usage
Configuration is performed via MODBUS registers or ASCII text commands. See the MODBUS mapping and ASCII command list for parameter details and examples.

Documentation & Catalogs
Catalog pages, product overviews, user manuals, product attachments, MODBUS mapping and ASCII command lists, and declarations of conformity are available as product documentation.
