Hi all,

i would like an RPM measurement with a namur sensor.

setup(TIA Portal):

6ES7315-2EH14-0AB0 Cpu 315-2 pn/dp

6ES7350-2AH01-0AE0 Counter module FM 350-2 (8 channels 10kHz)

right now i only receive the count pulses but i would like to recieve RPM. is it possible via the card iths self to calculate this or do i need to calculate this in the PLC if so does anyone have an TIA-portal example project?

kind regards,

snoopy

Hello Snoopy_87

measuring RPM directly with this card is possible. See details in manual here:

SIMATIC S7-300 FM 350-2 Counter Module

Also there is a sample available covering all functions of the card:

Sample program FM 350-2 zXX34_01_FM350-2.zip for TIA Portal V 11.0 + SP 2
