When playing the example from the README, I get the following error:

"binary.Write failed: binary.Write: invalid type int"

The only command that is working is the cpu information. Details: I'm using S7-PLCSIM Advanced V5.0 simulator together with TIA Porta V18 Simulated CPU Model: 1511C-1 PN Below the output of the log:

Hi, please check the following 2 points.

  1. DB must not be optimized.
  2. GET/PUT must be enabled

Hi, I checked the settings but I'm getting the same errors. image image

hongjinlin commented 1 year ago

Maybe there is a difference between the real hardware and the simulator, I encountered the problem "ISO : Invalid Buffer passed to Send/Receive '19'" in the S7-1200, which was solved by checking these 2 items

ghost commented 1 year ago

Are you also using simulator?

jiekechoo commented 1 year ago

I use PLC S7-300, 400, 1200, 1500, gos7 runs good. I guess you should use real hardware device. @warleyjr10

Thanks for the answers, I will be testing on real hardware devices

Are you also using simulator?

No, only the real machine
