	am using Allen Bradley Micro logic 1200 PLC. It is dual port PLC. We r sending ASCII code from PC to PLC having string length of 15. I wish to read each digit separately from received 15 digits. As the each digit & its position has meaning. I cannot send the separate data for each digit. May I hv software solution with details of instructions I should use to read the each data/ digit separately? I am using RSlogix software of AB. Pl. inform at the earliest. Dhananjay Pune

	Can't your Allen Bradley store each 8-bit digit into a table, then just translate them against another table that has the ASCII set as its offset? __________________ "Perplexity is the beginning of dementia" - Professor Coriolus

	I suggest you use AEX - string extract - to isolate each digit in the string, then ACI - string to integer - on each digit. You could do this in a loop, putting the results into successive locations in an integer file. __________________ "Love justice, you who rule the world" - Dante Alighieri
