I’m working with a Siemens ET200SP and I’m using the Siemens S7-1500 Ignitions Driver.
While everything else is working fine, I’m experiencing some trouble reading and writing LREAL Tags.
In Ignition the tags are declared as Float8.
If i write the value 0.0 from Ignition, i can see 0.0 in the PLC via TIA PORTAL and the same i can see in Ignition.
Writing the value 1000 from Ignition will produce a number wich is around 7.6e+21 in tia portal, but, i can see the correct value in Ignition.
I would like to understand if the problem is linked to the Siemens Driver, if I’m doing something wrong, if i choose the wrong driver for the PLC.
I tried to write on a REAL using in Ignition the Float4, and everything is working correctly.
