Note:
Attempting to access a device that is not defined in PLC memory causes the
HMI to display the “PLC no response” error message.
Note:
The PLC’s memory range may vary within the range supported by the driver. Use appropriate addresses.
Note:
*
The NfnBit, Bfn, Nfn and Ffn device types allow access to any data file (fff) and element (nnn) in memory. fff specifies
the data file 000-254, and nnn specifies the element number 000-254. For example, to specify Integer data file 15, element 7
(N15:7), select Nfn as the device type and enter 015007 as the Device address.
See Note 16.3.5 for more information on formatting Device Addresses.
