William_B Posts: 5225 Rating: (1204)	nagadevan.k ..... FIRST ONE ABOUT INDEX MODIFICATION KINDLY LET ME KNOW IN DETAIL.. ..... you are not supplying me what I asked for (sad) The closest I think we will get to what you ask is with arrays.. A variation on the theme is an array of a structure.. ..employed as.. ..or even.. w

nagadevan.k Posts: 28 Rating: (0)	i have program in mitsubishi lik the below attaached image where the address of the NO/NC/ COIL whatever , it can be changed based on a condition.. eg.M238Z1 is the address of coil, based on value of Z1 , address varies, lik if Z1=2, then the coil address will be M240...(i.e. 238+2).. want a similar kind of instruction in TIA v13, for s7 1500 cpu..ladder programming only. Hope you got the explanation what you asked for... Attachment Capture3.PNG (206 Downloads)

Hope you got the explanation what you asked for... Thank you - it is clear now. What you described is called indexed indirect addressing. If you want to do exactly what you ask then it is not possible in LAD (Ladder). Languages such as STL (Statement List) and SCL (Structured Code Language) will do what you ask. If you work with memory bits then creating and array of bits in a DB will be the best option. If you hope to manipulate inputs and outputs in this way.. then again there is a problem for LAD language.
