5.1.1 How to download objects in the FF segment
You have to download the following data for the function of the FF devices in a system:
● CPU data
– Hardware configuration of a CPU with connected FF segment (to the CPU)
– Program and connections (to the CPU)
● Schedule, bus parameters and interconnections (to the FF segment)
● Device parameters (to all FF devices)
Replacing devices
You have the following options for replacing devices with SIMATIC PDM:
● Replacement of a device with one of the same type
● Replacement of a device with a similar one
Requirement
You will have to read in the device parameters to the Engineering System before you assign
the parameters of the FF devices for the first time.
Note
Observe the following if you have inserted new FF devices on the FF segment or if you want
to use parameters of additional function blocks.
● The FF segment is stopped briefly during loading if it is downloaded completely (option
at the FF Link: "Always download FF Link and FF devices").
● The FF segment continues running during loading if it is downloaded in increments (option
at the FF Link: "Download FF Link and FF devices only in case of change").
● First, you have to configure all the interconnections.
● If required, correct the macro cycle settings.
Note
Downloading function blocks
It is not necessary to download an entire device if there are only minor changes. You can
download a group of function blocks or one individual function block for an FF device.
