plc5 message number reset fault

plc5 talk to HMI(hitech in taiwan),use preset message display in HMI,when bit in PLC is set 0,relative message could not be rest,for example:

b10:7/12 value is 1,relative message number(n11:9 in my pro)is 124,so HMI will display 124th message,but now when b10:7/12 is 0,n11:9 value is still 124,so confused about it...

attached is pro,hope someone can catch me and give me a hand.

Thanks.

you have to move some other number in to n11:9 if b10:7/12 isn't equal to 1.

b10:7/12
I\I oneshot MOV some #(0) into n11:9

Hi magicsmoke,thanks for your reply,I try my best to find whether some other number be put into N11:9,but find none,could you point it out for me if it exist?

do a seach in you plc 5 program for n11:9 there should be move instructions moving in those numbers into n11:9. your HMI is just reading the number that is put into n11:9. take a look at your data in n11:9 when there is no message in you display and that should be the number you can move into n11:9 when b10:7/12 isn't true.
