Hi Everybody,

I am using Directsoft32 to program koyo DL330 PLCs.

SP0 is the first scan bit for most Koyo's. You should check the memory or special register area of your manual to confirm for the specific model CPU you are using.

When that product line carried the GE label, the initial reset coil was address 374. Whether Direct soft takes care of automatically mapping SP0 to that address, I don't know. I could understand them doing it to maintain continuity across all product lines.

Note this section of the manual: Special Bits for the First Bit. It appears that for the DL330 it's C374 as Steve noted
