[@electricalautomation2831]

Sir, if the plc is programmed and I remove the SD card by switching of the plc.. Will the plc works properly? without SD card. Has the program saved in plc?

[@EASYPLCTRAINING]

most probably PLC will stop and give SF fault or all light will Turn ON

[@electricalautomation2831]

@@EASYPLCTRAINING so it will not work? .. After putting back the SD card in which the program is, plc will work and machine will run as normal

[@EASYPLCTRAINING]

@@electricalautomation2831 it should work as normal after putting back SD Card ... put SD CARD back and power cycle the PLC

[@mubarishussain3696]

Does the s7-300 work without a memory card?

[@EASYPLCTRAINING]

New models don't works with out memory card .... older version works with out memory cards with backup battery inside cpu
