Communication extension card
PROFINET communication card
-50-
analog and digital input terminals, VFD control panel, and communication modules (such as
RS485 and CH-PA01 adapter modules). To enable the control over VFD devices through
PROFINET, you need to set the communication module as the controller of the VFD device.
Actual value: An actual value is a 16-bit word that includes information about VFD device
operation. The monitoring function is defined through VFD parameters. The conversion scale
of an integer transmitted as an actual value from the VFD device to the master depends on the
set function. For more description, see the related VFD operation manual.
Note:
A VFD device always checks the bytes of a CW and reference value.
