PROFINET configuration files
SETTING UP A PROFINET CONNECTION (CPUM SW VERSION 081 OR LATER)
• If this flag is set to YES (the true condition), the PROFINET support is activated
• If this flag is set to NO (the false condition), the PROFINET support is not activated
• If this flag is missing (not defined), the PROFINET support is not activated (that is, the
default value is NO).
As show in Figure 10-5, for PROFINET communications, the PROFINET slots are defined at
the end of the [MAPPING] section using the PROFINET_CREATE tag. At least one register
should be defined by this tag. This means that the minimum PROFINET slot size is 2 bytes,
while the maximum slot size is 128 bytes.
In general, the slot size should be a power of two. However, there are two exceptions:
• The MPC4 card has a slot size of 74 bytes
• The AMC8 card has a slot size of 102 bytes.
As show in Figure 10-5, the PROFINET_CREATE tag uses the VM600 rack slot number (3
to 14), followed by the start and stop addresses of the Modbus registers where the card data
is mapped, depending on the Modbus configuration.
