Modern engineers expect 0-27648 (S7/TIA). S5 analog cards often use for unipolar and -27648 to +27648 for bipolar. However, some older S5 analogs use 0-2047 or 0-4095 . Always check the module manual.

A common mistake: Replacing a CPU without moving the EPROM results in a blank PLC.

The Siemens S5 hardware configuration is physically rigid but logically deterministic. Proper configuration requires strict adherence to:
