2 Functions of Devices in DVP-PLC After PLC LINK is enabled (M1350 = On), the data in D for data exchange will become: The Master PLC has to be SA/SX/SC/EH2/SV/EH3/SV2 series MPU, and the Slave PLC can be any MPU of DVP series. There can be maximum 16 Slave PLCs in PLC LINK. See the special Ds in the Master PLC corresponding to D100 ~ D115 and D200 ~ D215 in every Slave PLC in the tables of special M and special D. d) Example 4: Connection between Delta PLC and Delta VFD-M AC motor drive through PLC LINK for STOP, forward/reverser revolution and writing/reading of frequency.
Write the ladder diagram program into Master PLC (ID#17) M1002 Master ID# COM2 communication protocol Retain communication protocol Number of data read Number of data written Starting reference for Master to read from Slave Starting reference for Master to write in Slave X1 M1351 Auto mode M1350 Enable PLC LINK END D1480 ~ D1485 correspond to parameters H2100 ~ H2105 in VFD-M. When X1 = On, PLC LINK will be enabled, and the data in H2100 ~ H2105 will be displayed in D1480 ~ D1485. D1496 ~ D1497 correspond to parameters H2000 ~ H2001 in VFD-M. When X1 = On, PLC LINK will be enabled, and the data in H2000 ~ H2001 will be displayed in D1496 ~ D1497.
Modify D1496 to give command to VFD, e.g. D1496 = H12: enabling forward revolution of VFD-M; D1496 = H11: enabling reverse revolution of VFD. Modify D1497 to change the frequency of VFD, e.g. D1497 = K5,000: changing the frequency to 50kHz.
