Shorrock Automation
The new ASi controller from IFM Electronic is a compact ASi master system with an integrated mini PLC with options on various gateways such as Profibus-DP, DeviceNet, Interbus-S and Modbus, making it suitable for industrial use. If required, one or two masters may be integrated to allow a maximum 248-input and 248-output operation.
The ASi controller has full function capability to the M1 master profile. ASi data can be exchanged with a higher level computer via the built-in serial interface.
Local diagnosis is also possible via the built-in display and faulty slaves, configuration errors or ASi power failure, for example, can be identified.
For commissioning, addressing and parameter setting, functions are available. In addition, the ASi controller has a control processor which can be programmed from any PC via the serial interface, to IEC 1131-3 standards. IFM Electronics’ Ecolog ASi programming system is utilised for this purpose.
Data entered with ASi can be preprocessed and read out directly via ASi and for this purpose a program memory with 32 KB and a data memory of 32 KB are available. It is also possible to operate the ASi DP controller as a simple gateway.

A single platform for all automation functions
Beckhoff Automation
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.

Loop signature Part 2-4: Feedforward Control: Part 3
Michael Brown Control Engineering
Editor's Choice Fieldbus & Industrial Networking
In the previous articles in this series, the basic theory behind feedforward control was discussed, and it was also shown how to apply feedforward in practice. In this article, it will be shown how well feedforward can work in practice by giving a couple of examples.

Loop signature Part 2-2: Feedforward Control: Part 1
Michael Brown Control Engineering
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.
