Mitsubishi First Scan Bit

Hi everyone,

I am using a Mitsubishi PLC CPU model Q2ASCPU-S1 with GX Developer 8.12N and I am trying to modify an existing program to add a little house-keeping routine when my PLC is first turned on. My problem is that for some reason, the software will not allow me to use M9038 in my program. I know that M9038 is the first-scan bit for the A-series CPUs but I am not sure for the Q-series.

Does anyone know if this is the same for the Q-series and, if not, what the proper bit is, or even if it is even available?

Thanks
Steve
