Hi @Trex-2 ,

Can you send screenshots of your emulation settings in FlexSim?

If you open up the system console, then run the model, does it give any specific error messages?

Hello Joshua, I was not getting any error in system console.

I am able to write the kepware boolean tags using modbus protocol now but i also want to write other data types as float and word but i am unable to.

@Trex-2

For other data types, you will need to specify the Register Type to be something other than Coil, since Coil only handles Boolean. Not sure if you have done that already. If you have, please send us your Kepware configuration file.
