CANopen object dictionary when the remote virtual placeholder option is enabled in
a CANopen NIM. It provides a 32-bit subindex where the fieldbus master can write
a module reconfiguration. After the fieldbus writes to the VPCW subindex, it can
issue a reconfiguration request to the NIM that begins the remote virtual placeholder
operation.
