CAN Topology Improvements for an Energy Storage Site

,
TK Engineering Oy collaborated with a customer with the goal of improving their control system CAN communication implementation. The scope of the work was focused on the control systems CAN topology. Based on the initial system state an improved…
CANopen controller for independent metering control valves

CANopen controller for independent metering control valves

CiA 408 defines the CANopen-based control interface for valves including device state management, control signals, and common device parameters. This article introduces CiA 408, describes a valve controller deployment, and discusses deployment…
Use right network technology

Use right network technology for right purpose

Many of us is thinking every now and then, would it make sense to throw away other network technologies and just use Ethernet or WiFi for everything? It sounds attractive, that single network does everything, only a single tool chain is required…
Basic instrumentation before starting development of IoT service and analythics

Does your instrumentation support the new IoT services?

New IoT services New core services in the domain of IoT concentrate on early detection of various exceptions in the target process. The earlier detection shall work, the smaller deviations shall be detected. Reliable identification automatically…
Analysis of residual errors and their consequences in CANopen systems

Analysis of residual error and their consequences in CANopen systems

Residual error analyses for CAN networks have been performed for years. It is well documented, that commonly used equations do not fully apply for analytic computing of the residual error probability of CAN networks. Also too high bit error…
CAN physical layer, there is poor tradition in design of physical layer structures for industrial and machinery CAN networks

Physical layer really matters in CAN

Despite of the comprehensive knowledge of the CAN physical layer, there is poor tradition in design of physical layer structures for industrial and machinery CAN networks. Cables with "wrong" impedance (not matching with termination) are commonly…
CANopen offers further safeguards

CANopen safeguards to decrease the effect of residual errors further

In many applications, complex safety add-ons have been designed on top of existing control systems, which has lead to significantly increased complexity and costs. The most significant increase of the performance level can be achieved by replacing…
Systematic re-use of information

Systematic re-use of information

Systematic re-use of information and design processes defined by the selected system integration framework, such as CANopen, should be understood as an integral part of companies' design, assembly and service operations, instead of "just another…
Model-based design of CANopen systems

Model-based design of CANopen systems

Multiple disciplines for mechatronic system design co-exist, which hinder the utilization of software-oriented modeling principles e.g. UML. Existing modern tools may be integrated into a working tool chain. Model-based design has become…
CANopen in the frontline of openness

CANopen in the frontline of openness

Open knowledge is any content, information or data that people are free to use, re-use and redistribute – without any legal, social or technological restriction. Open data or open knowledge is one of the most recent IT megatrends. All around…

Experimental CANopen EEC management

Current CANopen design files do not support EECs (emergency error codes) with their human readable descriptions. This feature has become more problematic because of abstraction to parameters and signals. The system structure has become automated…
SI-Unit and scaling management in CANopen

SI-Unit and scaling management in CANopen

Various kind of inconsistencies have been typical problems in design of distributed control systems. The first solved issue was an automated generation of signal and parameter abstraction from CANopen project avoiding the inconsistent names…
Hydraulic valves driven by general purpose CANopen I/O

Hydraulic valves driven by general purpose CANopen I/O

Commonality between hydraulic valves driven by general purpose CANopen I/O and hydraulic CANopen drives Hydraulic valves have been driven by separate valve control electronics for decades. The tradition is becoming obsolete due to ever increasing…
