Hi

We are Building a testreg. we have a S7-1500 CPU 1512C-1 PN

The problem:

today we have 3 standart Digital outputs to simulate 3 hall sensors, this is to slow 

The standart outputs has a maximum frekvens of 100hz. We need a minimum of 500hz on the outputs. Is there a DO module we can use in our system or is there another way to solve the problem ?

The standart "PTO output" we can not use, because we have 3 channels

Thank you  

Hello.

Consider getting an S7-1200 to use for your lab simulation. It is good to have an extra PLC to do some side work with and buying S7-1500 hardware is expensive.

You might consider a PC-based signal generator solution along with signal converters with high bandwidth.

The PC would output at whatever frequencies and signal types you need. 

Signal conditioners would convert from USB-controlled signal conditioner output (0-5V TTL typically) to 0-24V. 

Opto-isolators they are sometimes called - take up very little room on DIN-rail.

It would be easier to reconfigure, which is always good for a testing rig.

If you opt for a PLC-only solution, it would be most appreciated if you would share your thoughts on the solution after it is working.

If you opt for a non-PLC solution, it would be useful to others to understand what reasons you thought it would be better for your test rig.

FYI, I have done similar things both ways.  Having the PLC do things is great if the project is extremely well defined (like to an ISO standard).  Having a PC do things is great if the project is likely to have scope creep (like a non-ISO standard or for R&D use).
