Dear All,
I would like to connect 4 wire pt 100 connection to SM334-0KE00-0AB0 Unit Modules. In my hardware setup, firslty i configure measuring type R-4L. I connect PT100 sensor to channel 0 >> 2(red cable), 3(red cable), 4(white cable) and 5(white cable). my problem is i can see analogue values at channel 1 even though i connect in channel 0.
so i think, my hardware configuration is wrong. so i change to RTD-4L in hardware setup. After that i see out of ranges at channel 0 (32768) and channel 1(-32768) . So kindly advise me and any samples wiring will be very much appreciated and will be helpful for me, please!
I have s7 300 module data manual but i quite not understand about Pt100 4 wire connection.
