S7-314C built in counter

Hi,

I've got an application that requires a sensor to detect product moving quite fast down a production line. I need two high speed inputs and wondered if the S7-314C built in counters could be used as high speed inputs for this purpose??

Basically I need to detect the product and then track it through to a rejector. So I need a high speed input for the sensor and also a high speed counter to count the encoder so that I can track the product through a FIFO until it gets to the rejector.

Does anyone know how to access the high speed counter on a 314C? Is it something that needs setting up in the hardware config? Or is it just a case of wiring the sensor and encoder into certain inputs?

Basically any information anyone has of configuring this would be appreciated? Anyone utilised one of these before?

Many thanks

The 314C has 4 x 60 Khz Frequency Measurement Inputs

See the Technological Manual here starting page 171 (Chapter 5)

Thanks for the link. I'll read and digest....

And yes i believe you do need to set the counter up in HW Config.

Its under the 314C > COUNT like this
