DPV1 Status Registers
The controller application program will use the DPV1 status registers as an
indication that the network Master has sent an unsolicited DPV1 Read/Write
request. The first will contain two bits which indicate if a read or write needs to be
processed. If this register contains a non-zero value, the Slave's user program
must create an appropriate response to this request by using a CIP MSG
command (shown in messaging section). The following table contains the
mapping of these registers.
