I read posts from other users for read/write Modbus and found they either had issue writing in multiple registers or writing into bit of single register.
In my case I am able to read 32 bit signed real values and Discrete Input values. I am able to write into Coil also.
Thing is I am trying to write into 32 bit signed real or 16 bit unsigned integer. However as soon as I add the tag into ignition, the other tags which I am reading goes into BAD state. The value goes RED.
Reading values behaves GOOD, when I delete the newly added tag for WRITE.
Write tag also shows BAD Quality, however I am able to write in it. The value I put can be seen in Schneider software, but in Ignition it says BAD Quality and does not read value.
Please see below snips,
Before adding WRITE tag:

Also I verified that there is 32 bit unsigned Real available at register 24
