When playing the example from the README, I get the following error: "binary.Write failed: binary.Write: invalid type int" and "ISO : Invalid Buffer passed to Send/Receive'19'" #59
Comments
Hi, please check the following 2 points.
|
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 |
Are you also using simulator? |
I use PLC S7-300, 400, 1200, 1500, |
Thanks for the answers, I will be testing on real hardware devices |
No, only the real machine |
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:
