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
