Hi All, I need help regarding FIFO logic. I have create data base to store data in data block. I able write data in data block also reading the store value in ascending order. E. g 1, 2, 3,4,5,6 up to 96 Buffer. Now I want read value again in descending order from 96,95,94,93 up to 1. I have tried logic for the same but facing problem to read value in descending order E. g values of index 5 not showing properly its shows index 4 values in final result. For reference please find the attached PLC backup. In PLC backup I have created VAT table nameFIFO_VIEW, M 59.0 is used to start FIFO. Every 10sec data will be log in DB123. M 400.1 is Read data log in ascending order and M 400.2 is to read data in descending order. Please check program guide me. Regards, Yogendra AttachmentTest.zip (90 Downloads) |
