#124070 - Memory Map
Responding to: ???'s previous message
Any words of wizdom on any other possible problems I may encounter with Modbus?

How familiar are with the modbus memory map and the different categories of I/O?

In other words, does the following mean anything to you?

Register Range 0 - 10000: Coil
Register Range 10001-30000: Input Status
Register Range 30001-40000: Input Register
Register Range 40001->: Holding Register


I have written an article (yet to be published) that covers this in passing, but it is now covered a publishers agreement so I don't want to put it on a public forum. If you provide me with an e-mail, I will send the relevant text.

If you don't want to put your e-mail here, contact me through my address in my User Profile.
