12. Communication Design Examples Program Description: z When X0 = ON, the data exchange between Master and 3 Slaves will be performed through PLC LINK by the ways explained below: D0~D99 of Slave 1 will be read to D0~D99 of Master. D100~D199 of Master will be written in D100~D199 of Slave 1. D200~D299 of Slave 2 will be read to D200~D299 of Master. D300~D399 will be written to D300~D399 of Slave 2. z Assume that the data in D for data exchange between Master and Slave before PLC LINK is enabled (M1350 = OFF) are as below: After EASY PLC LINK is enabled (M1350 = ON), the data in D for data exchange becomes: z In Master PLC, set the starting Slave ID (D1399 = K1), i.e.
Slave ID 1# corresponds to Slave1 and Slave ID 2# corresponds to Slave2. z Station No. of Slave should be continuous and different from the station No. of Master. Only the SV/EH/EH2 series PLC can be Master, but all DVP-PLC can be Slave. z When X0 = ON, PLC LINK will be enabled. If enabling action is failed, M1350/M1351 will be OFF and X0 needs to be activated again.
