Hello youssef; PED, in a S7-300 or a S7-400 CPU, would designate a peripheral input double-word address. Peripheral addresses refer to any address which is outside the Input/Output image tables, which are generally used for digital addressing. So analog and communication (Profibus, Profinet) addresses use peripheral addressing. See the following FAQ for more details: https://support.industry.siemens.com/cs/ww/en/view/18325417 The "E" means input in German ("Eingang").. If your program uses English mnemonics, you would write PID (I as in Input). For Outputs , you would write PAD (in German mnemonincs, "A" as in "Ausgang") or in Eglish mnemonics PQW (Q for Ouptput). Some examples in English mnemonics: PIW256, PIB258, PID260 PQW 262, PQB 264, PQD272 Hope this helps, Daniel Chartier |
