I am currently writing my first HMI using the Automated Solutions Modbus master to close coils in a Modicon TSX 07 nano PLC, also to access an internal memory word %MW05
I am looking for information as to how to use modbus addressing ie
DATA ADDRESS COMMAND POINT TYPE
00000-09999 01 COIL STATUS
10000-19999 02 INPUT STATUS
30000-39999 04 INPUT REGISTER
40000-49999 03 HOLDING REGISTER
to access the address register in the Modicon TSX 07 nano PLC. I am not able to use the data addressing above to get the right information from the nano using it's system ie
%M0 to 127 = Internal Memory Relays
%MW0 to 255 = Internal Word
etc
Also any information as to how to make a cable connection would also be appreciated. The extension port is labled A, B and SG, there is no information as to whether A is Recieve and B is Send or reverse.
Any other help on how this can be achieved whould be greatly appreciated.
Cheers
