After setup/test I noticed I was able to read the values on the GOT but was not able to write. In the parameter settings for the RCPU there is a special option to select "enabling" the write by SLMP to the CPU. (see 2nd screenshot) After change I was able tor read/write the values via de SoftGOT towards the RCPU For the parameters for FX5 a was not able to find that same setting, but I guess this is managed by the security settings. See screenshot. In attachment the 2 sample programms SoftGOT2000 and R CPU project Hope it helps you SLMPSGOT_RCPU.GTX SLMPSGOT_RCPU.GTX GXW3_R04_SLMP.gx3 I will give this a try later on today and provide feedback! Thanks so much for the response! Share this post Link to post Share on other sites
