M172 with Delta HMI type DOP107-EV

[WADDAH]

Dears .. The client has already bought a Delta HMI type DOP107-EV , and he want use it to read and write data from Modicon M172s that i have already programmed in his project . I configured the modicon M172s as slave , and the Delta DOP as a master .. I Have exported the modbus Data CSV File from M172s and tried to use addressed in the Delta DOP software but unfortunatelly I could not read data ... Are those addresses in CSV file can be used for all types of HMI .. Please help if you have any idea Best Regards #M172 #modicon #Machine

Hello,

consider that all registers of TM172 are holding registers, you can use commands 3 for reading and 6,16 for writing. Registers are base 1, you can easily test using Modscan entering the same addresses.

Keep also in mind that TM172 answer with an exception if you try to read a not existing register with a multiple read (you might need to decrease the maximum number of registers to be read in one shot on Delta side).

And you get a big problem if you have not only continous register adresses.You have to check this point in ESME HVAC.

Hi,

The variable ordering in the Delta panel's CSV file is different from that in the Schneider PLC's CSV file. It might be easier for you to first try a test by creating the variables individually in the Delta HMI, and then attempt to retrieve the data using the CSV file.

Thanks

... I agree with you that we cann't use the exported csv data file from M172 Directly ... 

Could you please tell me how to put this address in Delta HMI DOP as an example ... 

HMI is the master and M172 is slave ...

Best Regards
