CBL, converter between CC-Link and MASTERDRIVES
CBL converts the CC-Link profile for inverter to the data structure of
SIMOVERT MASTERDRIVES.
It converts the control bits (remote IO bits RYn....) to the bits of the
control word from the converter. In other direction the bits of the status
word are translated to the remote IO bits RXn... . Chapter "Appendix"
describes the rules of bit generation.
The CBL also transports the reference values (setpoint) and the actual
values (incl. monitoring) between CC-Link interface and the dual port
RAM interface of the MASTERDRIVES. CBL translates between the
different data formats by calculating with scaling factors.
The handling of parameters at CC-Link by Command code execution
is transformed to the PKW task handling with PKW request and reply of
MASTERDRIVES.
