Product Description

Description

The HVAC ModbusIO2 Library integrates powerIO® H1.X I/O modules directly into your CODESYS V3 application. The library enables quick commissioning without complex engineering – a master function block communicates with the respective slave blocks of the I/O modules.

Description and documentation: HVAC ModbusIO2 Library

This enables you to, for example:

Access analog and digital inputs/outputs via Modbus RTU
Select sensor types (PT1000, Ni 1000, NTC 10k, etc.) directly on the function block
Configure I/O handling such as negation, two-point function, limit value, or filter function
Control 3-point actuators with the H1.4DI2DO-R-3P module

Supported Modules

H1.8AI – 8 analog inputs for sensor values
H1.8AO – 8 analog outputs (0..10V control signals)
H1.16DI – 16 digital inputs for signals
H1.8DO – 8 digital outputs
H1.8DO-R – 8 digital outputs with relay
H1.4DO-R – 4 digital outputs with relay
H1.4DIO-R – 4 digital inputs/outputs with relay
H1.4DI2DO-R-3P – for 3-point actuators

Key Features

Parameter window per module for slave address, bus timeout, send and query times
Optimized for the CFC editor
Safe output states before initialization (xUseSafeStateBeforeInit)
Ideally combinable with the HVAC Building Automation Package and the powerIO® system
