Logitech Automation, a company that operates in the design of automation plants and systems, wants to build a new type of test bench for three-way valves, in which the critical functions are managed by a PLC and all user interaction and test strategy are entrusted to a PC. Having in its interior a highly experienced team of PLC programmers, Logitech Automazione relies for the PC part on T4SM.
Application requirements are:
T4SM has developed a custom application for Logitech Automazione based on iDaq, a configurable and expandable software for acquisition, visualization and data insertion, also developed by T4SM. Below the diagram of the solution is shown.
In the machine, there are three pressure sensors and a torque sensor, which signals are acquired through a CompactDAQ to iDaq.
The three-way valve to be tested contains a ball, which rotating regulates the passage of what the valve has to convey. The ball rotation is driven by a motor controlled by a Siemens PLC. During the ball rotation, the torque is controlled.
With the proposed solution, all the goals have been achieved. The immediate benefits experienced by Logitech Automazione are in particular:
Combining the PLC with a PC and iDaq, Logitech Automazione obtained the best of available technologies in security, versatility, and ease of use.
Working in a coordinated way, Logitech Automazione and T4SM could create, test and deliver the test bench to the customer in a very short time.
While working closely with T4SM, we could appreciate the professionalism and the seriousness with which the system issues to be realized were analyzed, processed and the possible solutions evaluated, shared and subsequently implemented. We also really appreciated the availability and flexibility in the planning of the work to be performed which for a dynamic company such ours is fundamental;
Result: goal achieved admirably.
