The Master PLC has to be SA/SX/SC/EH/EH2/SV series MPU, and the Slave PLC can be any MPU of

DVP series.

There can be maximum 16 Slave PLCs in EASY 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 EASY PLC LINK for

STOP, forward/reverser revolution and writing/reading of frequency.

D1480 ~ D1485 correspond to parameters H2100 ~ H2105 in VFD-M. When X1 = On, EASY 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, EASY 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.

The Master PLC has to be SA/SX/SC/EH/EH2/SV series MPU, and the Slave AC motor drive can be any

VFD series models except VFD-A.
