GX Works 2 Pointer count

1 post in this topic

Hi I am working through a project using GX Works 2 for a Q12H CPU. I have approx. 52 analogue inputs to process and have created a block to do this with 7 networks (limiting, scaling, high and low alarms, 10 inputs, 8 outputs). My question relates to the number of pointers allocated to each block. In my device/label automatic assign area I have a pointer range of 2048 - 4095 (2048) when I populate my 52 function names in the global label section I have an error that the number of pointer points falls shorts. ok so I delete and start inserting one at a time and can see that for each function block there are 186 pointers used (53 words, 12 bits, 6 timers). Is there anything I can do to reduce this? It seems like a bit much for a 7 network function and it doesn't look good for the rest of my program as I am only setting up my IO at this stage and have used up my pointer range already.... I have attached a screen shot of my scaling block, networks (reduced to 3 networks with no difference in pointer counts) and the local label for reference. Thanks JT Edited by justwhy2003
