New Modbus mapper feature

[George Przygoda]

Nice touch, that thing will help many modbus beginners.

Could you add two additional functions to this program?  This is what I've found useful when testing modbus devices:
One is the ability to set start and stop register, eg. 100-110 will read from 100 to 110 by the "read length" increment. Then show that in the list. The other is cyclical read of set registers (every x seconds) until stopped.

Hi Zoltan,

I think what you are asking for is already existing in a ModBus scanner tools, that are available free of charge. Basically when it comes to ModBus integration, I always use first such scanner tool together with RS232/RS485 interface to make some tests, to check communication and register values at the slave. After that I am implementing ModBus integration to the system.
I have found it is the fastest way, much faster then to load configuration to the device test, change, test, test .... etc ....
Of course the feature above is a great help, but personally I will stay on a scanner tool that has many more features for testing the communication.
