Modbus RTU I/O Modules (RS485)

The I/O-Modules of the MX110 Series offer a cost effective and flxible solution in distributed
automation systems. Unlike many centralized I/O systems, the operation of these modules requires
no need for involving any bus couplers nor supply modules because each MX110 unit has its own
power supply and communication terminals on board. With the proven RS485 interface and
intelligent functions, such as pulse counting or sensor state diagnostics, the MX110 modules can
be used in different filds, e.g., building technology, process industry, etc. These robust digital and analog
modules are used for decentralized data acquisition and process control as well as they can serve as
a proper supplement to existing systems or new automation systems to be deployed.

The use of I/O-Modules provides:
• Signifiant reduction of cabling resulting in the
lower susceptibility to interferences
• Reduced setup time due to direct connection of
sensors and actuators
• Higher flxibility of the entire system due to free
placement and easy replaceable elements
• Better system adaptability and extensibility
Applications:
• I/O signal transmission to a SCADA system or HMI
(e.g. operator terminal)
• Increasing the number of I/O points of a PLC
• Any RS485-capable fildbus network with
communication via Modbus RTU/ASCII

Functions:
• PWM
• Pulse counter function
• Sensor-based status diagnostics
• Diagnostics of RS485 network status
• Additional logic functions at digital
inputs and outputs
• Transmission protocol autodetection
• Generation of appropriate error signals
or alarm signals
• DIN rail or wall mounting

Confiuration
The confiuration software is available free of charge.
A simple and convenient interface enables fast and
uncomplicated confiuration of I/O-Modules.
The confiuration mask can be saved as a fie.
