Support Questions / Delta plc with advance hmi Addressing problem
« on: October 10, 2016, 12:50:39 AM »
hello
first i want u to know that am new in plc world and in vb programming
i tried to communicate with the plc throw the computer
so i started with dmt.dll the library of Delta automation
i built my first project it worked fine with serial com and local network
so i still want to build one that remotely control the plc or at least monitors it
the problem is in dmt library i can chose the ip but not the port
thats what made me look for anther modbus and brought me here
now i am trying to use advance hmi
i couldn't read or write any thing to or from the plc
the driver am using is ModbusTCPCom
the plc is delta dvp12se
i think my problem is with modbus addressing
for example i wanna read the address (d502)
when i write it in the address value it says on the digital panel text ( invalid address ...)
so any one can tell me how to solve it
or show me how to transfer the address to the write way
with thanks
