Modicon SA-85 card


Thread Starter

Just thought I would let you know that I have successfully reverse engineered the memory map of the SA-85 (ISA <-> Modbus Plus) Card from Modicon. This effort was done without any help from Modicon (directly anyhow). You can expect to see sample source code within a week.

Modicon was interested in helping me out *until* they found out that I was going to be giving my work away. Seems like they don't understand the
"community spirit" we try to impart in our work. Oh well.

If anyone is interested in specifics, let me know and I'll post what I know to the linuxplc list.
