you can clear the memory after connecting the plc in software .. first use auto check option in " online PLC " then reset the memory

i solved the error. as in winproladder there is an option " Auto Check" . you should must click either you know your port or not. it has resolved my problem as well .

can anybody explain the pid command for me .. it will be great for really help. i am confusing the 25 registers used in pid loop.. as i cant understand it. s3+0 bo and b1 how can i used the bits of a register. on which register i can control the error between set value and process value. how can i control the error difference between set value and process value. for example if set value is 5.5bar for a process and process value is 4.5 then value should be relative option depending on error
