Access Between Dvp-Eh2, Dvp-Pm (As Master) And Dvp-Pm (As Slave) - Delta DVP-PM Series Applications Manual

7.1 Access between DVP-EH2, DVP-PM (as Master) and DVP-PM (as Slave)

When DVP-PM is used as Slave, there is a data exchange area in DVP-PM which corresponds to the control
registers (CRs) in the Master. The data exchange area is consisted of consecutive special registers, and users
can utilize the data exchange area for accessing data between Master and Slave as well as performing motion
control functions through a Slave DVP-PM.
7.1.1 The Structure
DVP-EH2 and Master DVP-PM apply FROM/TO instructions to transmit commands to Slave DVP-PM
for executing motion control subroutines.
DVP-EH2 and Master DVP-PM apply FROM/TO instructions to access the control registers (CR#0 ~
CR#199, corresponding to special registers D1500 ~ D1699 in the Slave) in Slave DVP-PM.
