  1. Hello evreryone! I want to build a Gx Work program.   The condition for auto start is when a low limit sensor is detected.   When the high limit sensor is detected, supply to the tank is stopped.                 The order in which the tanks are opened is 4,3,2,1.     Tank closing order is reversed.         Valve 5 must be closed when liquid is being supplied to the tank.   The completion of supply to the tank is confirmed by the high limit sensor. I use MOV transfer e.x D0 K1 Y01 MOV K2 D0             Y2             Y3 I want to open coli Y1 Y2 Y3 every valve how to open toether. Thank you

  3. hallo all, I want to ask if I click "read PLC Data" the "points" will appear, I use the QY18A output module that uses 8 points but there is no choice, the smallest is only 16 points.  so I can't put 148 in the "start XY" column ... will it affect the I / O address in the program?
