Pro Tool and WinCC flexible
The SIMATIC HMI can be configured flexibly with "Pro Tool" or "WinCC flexible".
The following specific settings for drives must be observed when configuration is carried out
with Pro Tool or WinCC flexible.
Controllers: Protocol always "SIMATIC S7 - 300/400"

Table 7- 26 Variables: "General" tab
Type Depending on the addressed parameter value, e.g.:
INT: for integer 16
DINT: for integer 32
WORD: for unsigned 16
DB
Parameter number
DBB, DBW, DBD
(data block offset)
Drive object no. and subindex
bit 15 ... 10:
Drive object no. 0 ... 63
bit 9 ... 0: Subindex 0 ... 1023
or expressed differently
DBW = 1024 * drive object no. + subindex
Length Not activated
You can operate a SIMATIC HMI together with a drive unit independently of an existing
controller.
A basic "point-to-point" connection can only be established between two nodes (devices).
The "variable" HMI functions can be used for drive units. Other functions cannot be used
(e.g. "messages" or "recipes").
Individual parameter values can be accessed. Entire arrays, descriptions, or texts cannot
be accessed.
