Turck is offering its new BL67 system I/O. The BL67 solution combines all the flexibility of in the cabinet PLC I/O systems with modularity, ruggedness, and connectorisation. The BL67 product family complements existing AIM, BL20, and piconet products to meet the needs of unique applications, such as small machine or conveyor systems requiring IP67 protection.
The BL67 system is made up of a gateway, base modules, and electronic modules. The I/O modules are not dependent on the fieldbus protocol. The gateway coordinates the entire I/O data exchange and generates detailed diagnostic information for the control platform. Gateways are currently available for DeviceNet and Profibus-DP. The BL67 system also offers group, connector, channel and module diagnostic information.
The BL67 system size allows up to 32 electronic modules, up to 256 digital or 64 analog I/O, up to 1 metre long, and is DIN rail or flange mountable. Electronic modules are available in digital, analog, temperature, RS232/485, and more, with 2, 4 or 8 channels. Electronic modules are replaceable without removing I/O wiring and are colour-coded for easy identification. A mechanical key matches an electronic module to a particular base module, preventing insertion of an incorrect electronic module. The power distribution module supplies 24 V d.c. to the electronic modules and can create isolated groups of I/O. The base modules are available with eurofast, minifast and picofast connectors. Connectorisation eliminates wiring errors and reduces wiring time and cost.
The IOassistant software is available for the BL67 system. The software includes engineering, parameter set-up, documentation, commissioning, and diagnostic function for online or offline usage. Although the IOassistant is not required to set up a BL67 system, system engineers agree it makes their job easier. The IOassistant is free of charge and can also be used for the BL20 and piconetI/O systems.
Why secure industrial communication depends on deployment as well
Fieldbus & Industrial Networking
The Industrial Security Harmonisation Group has released a joint industry perspective highlighting a critical truth in industrial cybersecurity: secure communication is not determined by protocols alone, but by how they are deployed and managed in real-world environments.

Fieldbus & Industrial Networking
The introduction of TwinCAT in 1996 marked a decisive evolutionary step for PC-based control. Today, the TwinCAT platform combines all automation functions in a strictly deterministic real-time environment, from PLC and motion control through CNC and measurement technology and beyond, to vision, robotics and pioneering AI tools.

Fieldbus & Industrial Networking
Feedforward control is a powerful technique that can dramatically improve control variance in cases where load changes cause big deviations from setpoint and the actual process dynamics are too slow to allow the feedback controller to operate fast enough to catch these disturbances.
