Hi Friends,
Have anybody faces this problem before? the reading of scada(citect)
showing -negative value while the setting ranging is 0 ~ 200 deg c ( 0 ~ 27648 ). PlC i am using S7 300. The - negetive value appear not very frequence, several times per day, and funny thing is only occur to my temperature analog signal but not level, pressure signal.
Is that because of i am using s7 profibus for communication?
i dunno this kind of system is suitable for communication or not.
Thanks
