Guys I am new to here and having some difficulty with RSLogix5000. Basically I am using Redlion G310 HMI with AB CompactLogix PLC. HMI is perfectly working fine when reading Tag Bits from PLC. I can also set the output high or low from HMI without any problems. My problem is that when I have an Output that is part of the Main Routine (Program) , I am not able to over ride it. The only way to change its status is by using FORCE On or Force off from RSlogix5000 but how can I force it ON or OFF using my HMI. How can I access the Force Mask table from HMI ? IS there any other way to do it. The program is written in Ladder Logic. I couldn't find any instruction that would allow me to manually over ride.
AND /OR logic will not work in this case because if the HMI tells it to 1 and by default it is 0 we want 1 as a result whereas in opposite case if HMI tells it to be 0 and program tell it to be 1 we want 0. In other words we want
PLC HMI
1,,,, 0 = 0
0 ,,,,1 = 1
which is not possible ?
Any help would be appreciated.
