Good to know
|Minimal requirements for the PCD3.B160 are PG5 2.0.210 and firmware 1.16.52 on the PCD3.|
For accessing a PCD3.B160 the media mapping must be used (direct access to the I/Os from the DDC Suite is not supported).
It is not possible to use the PCD3.B160 on a PCD3.T760.

How to configure a PCD3.B100 on a PCD3.T760? (FAQ #100445)
The PCD3.B100 is a special module since there are input and output flags to be mapped onto the same module placed on a PCD3.T760. Because the S-Net SBC Network Configurator does always assign arrays of 8 flags or bits, some of them are to be named but cannot be used by the user program.
The definition of the amount of inputs and outputs on the module
The specification, which data points are inputs and which are outputs is done in the "Edit Parameters" window. Open it by clicking the button "Parameters..." in the "Define modules" window (see below).
Mapping the I/Os to PCD flags
When mapping the I/Os to flags, there are two arrays to be edited; one for the inputs and one for the ouputs. Note that there are always 8 flags to be mapped (also if only two of them are used as inputs). The flags that are not used must also have a (unique) symbol name.
It is a good practice naming the not used flags with a clear name (e.g. NotUsed00, NotUsed01...). Each B100 will need 8 such flags (e.g. the first two for the output mapping and the other six for the input mapping as in the pictures above).
Make sure that all the distributed symbols are unique (CPU wide). Otherwise the communication will not work properly (I/Os will be set uncorrectly)!
