  1. I've got a PLC stack with a Q64AD analog-digital converter card. I am attempting to read the digital output value of channel 1 but I am having issues. First of all here is my simple PLC program: I got the program from the Q64AD user manual. You can see there is a blue '0' on the right of line 0. I assume this is the value that is being read? When I monitor the D11 device in GX Developer it shows a '0'. The following is a screen from Online > Monitor > Buffer memory batch. My card has a base address of 0x60 and channel 1's offset is 11d (0Bh). The value on the highlighted line does change so I know that the analog card is correctly picking up on current changes from my source. Lastly here is an image of my digital inputs. I have set up the Q64AD card through the GX Developer PLC Parameter window and left all settings as default. I initially used 'K11' instead of 'H0B'. I have also tried using the MOV command (MOV U0\G61 D11) but that game me the same result. Can anyone spot the flaw in my program of configuration? Do I need to configure the PLC in order to use the 'D' devices? Should I try copying the value somewhere other than D11? Thanks
