Omron: are usage of pointers possible in ST?

_MG_ · Dec 3, 2015

Hello all,

I want to transfer some complex ladder logic into structered text, pointers are used a lot in this ladder code and I can not found how I can do pointers in ST properly. Anyone who can give me some pointers on how to do this if it is possible (pun intended)

Best regards

MG

what means pointers in Omron dictionary

_MG_ · Dec 3, 2015

I mean by pointers the usage of *D123 or @D123 in move instructions or using MOVR instruction in Omron and setting/manipulation IR/DR register for indirect addressing of values.

Hey Osmanmom, thank you for the links, however these links all talk about indirect programming in ladder logic, I want to do this in ST or structered text, more specificly I want to do this in an ST Program (where I then can append a cyclic task to it). I'm talking here for CJ1M Omron CPU's
