How to set a coil as write only?

Hello,

Lookout 6.6

How do you set a modbus member, i.e. a coil (point 1 for example) as write only?

Thanks in advance.

Here's a bit more detail.  Our RTUs communicate via radio so latency is a factor.  Lookout always is trying to read from these write only coils and this causes additional delays. If we could eliminate all the unnecessary radio traffic that Lookout creates reading coils that are write only, it would be very helpful.

Try using two Modbus objects.  One polling for reads, the other with no polling (immediately write outputs) for writes.

Thank you, a great suggestion (having two objects)

I will do some experiments...

From what I've seen from the trace, Lookout immediately reads the coil after the write, i.e. not as part of the poll, inorder to sync with the hardware.  I wish I could turn this off.  

Thanks again.
