Hello M. Vadigard; Are you thinking of using a S7-1200 PLC, as this thread refers to? The mechanism for detection and diagnostics of wire break in S7 PLCs is the diagnostic error interrupt, OB 82. See the description in this section of the S7-1200 programmable contoller manual: https://support.industry.siemens.com/cs/ww/en/view/109478121/70491858187 This next document will show you the steps required to enable the wire break detection and evaluate it in OB 82; the example uses an analog output module, but the same reasoning applies to an analog input module: https://support.industry.siemens.com/cs/ww/en/view/42320122 Hope this helps, Daniel Chartier |
