dear all, have a good day: i am mahmoud, from Egypt, i have a problem with S5 95U that i cannot access to the analog input on the CPU,the onboard i/os, i have just graduated from the faculty, and i'm new in this matter. i have written my program using PG 2000, i added new OB1 and i wrote my program in it directly calling FB250 which is the function used for the analog inputs, and i have constructed a DB1 to get the value of the input analog in it. as regard the H/W, i have a PT100 sensor and a converter which is used to convert the resistance o/p in 0-10v signal. i have taken a screenshots for my program to make it easy to understand. please help me to solve this problem i'm wating your reply as soon as possible ---------------- Attachments5.docx (266 Downloads) |

You use in your program DB1 for data storage. This is not good because the DB1 is used for internal purposes. You must also released the analog input for reading in DB1. Here you can download the manual for the S5-95Us. Attachments5_2.docx (266 Downloads) |

Hi rimoon, See section 12.1 in the manual - "Specify in DB1 which analog inputs are to be read into the PII cyclically" Regards |
