I have o question as : - When i research SFB47 and SFB48 funtion bock, i see both SFBs have output is COUNTVAL, with SFB48 have output MEAS_VAL. Output "COUNTVAL" in 2 SFBs is look like ? . If not, i want know the defference 2 oput ? - Can i use output COUNTVAL in SFB48 as in SFB47 to read number pulse count ? - How is config HW with 4 chanel ? If i want use encoder,what is Operating Mode i must use ( count continuos; count one ; count priodically ; or Pulse - with modulation ?. Where can I rely on to determine operating mode for chanels ? - Now. i want to design a weigh belt feeder use PLC s7 300. If you have a project alike, please share for me. Thank you for help.
