Dear Rishikesh, You are getting a IO access error. You are trying to access a PIW/PQW address that is not present in your hardware configuration. Cross check your program (compare HW configuration and Cross reference ) and make the required changes. Look for address 280. With regards, nandgate.

Sir SF fault does not come before Control ON, it comes only after Control ON We have previous PLC backup, compared h/w configuration and Program, we did not find any difference, moreover one of our persons told that a week back there was no SF even after Control ON so v r trying to find out reason for SF after Control ON Regards, M.

Hi What do the wordaddress 280? you can also try selecting the blocks in STEP 7, then press CTRL + ALT + R together, select the occupation of the inputs, outputs, flags, timers and counters, and if you look at the inputs and outputs is occupied the area (MB280-MB281). |
