Dear 'collegues', I am looking for a solution for the following problem: I have to update a machine to measure electrolytical capacitors. The throughput rate of the machine is 6000/hour. The whole machine is controlled by one axe, which therefore makes two revolutions per second. I want to remove a large number of sensors and use an absolute encoder instead. This will be my trigger for all activities. The measurements have to be with Itronics Fuchs equipment using IEEE (possibly RS232). We want to control the machine, make settings to the measuring-equipment bij computer and some day collect the measurements. The problem I run into is: - When using a soft-PLC I do not know how to integrate IEEE into this (The books do not refer to this at all) - When using PLC I do not have the ability to use IEEE (PS: I know Philips PC20 - this does not mean I cannot use anything else) and even when I will use a PLC together with a PC I do not have a PLC which has a cycle time of 2 msec or less. - I have thought about using labview with a IO-card and an IEEE card but I have trouble trusting WindowsNT I need a reliable and fast system. When a measurement is started, after getting the result 'wrong', I have to activate an output for ejecting this product directly. Can I integrate IEEE into TwinCAT, WhizPLC/CON, etc.? Does anyone know of a PLC that has a cycle time less than 2 msec. (for about 1 kb - preferably more) ? Does anyone tell me if and how I can trust windowsNT, with labview for this problem? I know I could use Linux, but have zero experience and I am alone on this, no fancy team and so on. I hope any can help me further, Sincerely yours, Harry Friemann Assistent Technische Informatie Systemen BCcomponents, afdeling R&O Tel: +31 38 4575 317 Fax: +31 38 4575 298 E-mail: [email protected]
