AH500 Programming Manual Example 3: 1. Function code 05 (16#05): The AH500 series PLC reads the data from several bit devices which are not discrete input devices. 2. AH500 series is connected to the DVP-ES2 series PLC. ASCII Mode: The AH500 series PLC is connected to the DVP-ES2series PLC. When SM96 and X0.0 are on, the AH500 series PLC sends and receives the Y0 (Y0 address is 16#0500) commands from DVP-ES2. 3. After the reception of data is complete, it will check the data format of what have been sent from the DVP-ES2 series PLC. If the format is correct, SM100 will be ON, and if not, SM102 will be ON. 4.
When the DVP-ES2 series PLC receives the communication instruction, the Y0 will be switch to ON. 5. This function code is for writing. Thus the n vaule in this instruction will not be used. 6-420
