making automatic controls with PLC
(OP)
Hi all,
First of all I apologize for my bad english. I' try to be concise.
My company manufactures curb and gutter machines, concrete slipform pavers and canal machinery. We are introducing a new control system using the following components:
PLC: OMRON CJ1M CPU13
Sensors: DISONIC US 18K 1000 SAK/SYSC (Analog)
My first question is about the sensors. As far as this problem is concerned we are having a lot problems with the synchronization working with two sensors. The manufacturer says that you can use this sensors synchronizity, but it's not true. In fact we have to shoot the two of them separately. Besides this sensors are very sensitive to "noise", so we are introducing filters.
I have to aclarate that this sensors read from a wire horizontaly and verticaly.
We are thincking that using this sensors is a wrong way. Any suggestions? Maybe other mesure system with no contact with the wire.
Thank you
Regards
