Every tag connected to the plc just make an error, "can't be write on plc"... You'll found in attachment some screen of my configuration between my HMI and my PLC. I can ping the plc from the hmi Attachment Capture267.PNG (1133 Downloads)

You can check it in the 'Protection and security' section of the PLC properties in the project. Also, check that in the PLC tags table, the tags used have the 'Accessible/Writable from HMI/OPC...' check mark.
	A rating will be well appreciated.

And download Hardware configuration to S7-1500 again. Best regards, Wizard
