DeviceNet Network Scanner DVPDNET-SL 4.2 Data Mapping Areas mapping relation is unchanged and user has no right to revise this area. The data mapping introduced in this chapter is the data mapping between PLC MPU and DVPDNET-SL. The Max 8 PLC DVPDNET-SL modules can be connected to PLC’s left side. After all DVPDNET-SL are connected to DVP-SV, DVP-SV will distribute data mapping areas to every DVPDNET-SL. The index of DVPDNET-SL is its unit number. The first DVPDNET-SL on the left hand side of DVP-SV is No. 1, the following DVPDNET-SL modules are No. 2, No. 3, No. 4 and so on. 4.3 I/O Mapping Table (as master mode) As DVPDNET-SL of unit No.
1 serves as master mode, the data mapping areas are distributed as below table.
