Process Data, Pcd - Danfoss VLT 2800 Manual

I Process Data, PCD
The VLT 2800/FCD 300 DeviceNet offers a flexible
way for the user to customize the number of Process
Data (I/O words) and the functionality of each word.
To activate the user definable Process data the
user has to select the I/O Instance 101/151 in
parameter 904 PPO selection. This will change
the I/O size to four words in the input and output
area. This selection uses the Danfoss specific
profile for the Control-/Status word as well for the
Main Reference Value/Main Actual Value.
The first two words are fixed on the VLT 2800/FCD
300 DeviceNet, whereas the input and output PCD1
24
®
VLT 2800 / FCD 300 DeviceNet
and PCD2 can be selected by the user. The number
of PCDs active in a system is fixed to 2 words.
NB!:
The changing of Parameter 904 PPO selection
is first active at the next powerup, and it may
change the mapping of the Masters (PC/PLC).
To enable the use of PCD data of the VLT
2800/FCD 300 DeviceNet the contents of each
single PCD word has to be configured in Parameter
915 PCD write configuration and 916 PCD read
configuration. Changing Parameter 915/916 has
immediately effect on the PCD data.
