New Functions of DVP24SV2 (in Comparison with DVP28SV) 1. Analog-to-digital modes are added. Two analog input channels (AD0~AD1): The analog input function of a PLC can be enabled only when the PLC runs. The relation among analog input modes, digital values, and conversion time is described below. Registers related to analog input: Mode Digital value Conversion time Voltage 0 V~10 V (12-bit) 0~4000 D1118 Conversion time is limited by a scan cycle. Current 0 mA~20 mA (11-bit) 0~2000 Device Function number D1062 (Latching device) Number of analog input values (AD0~AD1) by which the sum of analog input values is divided: 1~20 Default value:
K2 D1110 Digital average of analog input channel 0 (AD0) If the value in D1062 is 1, the value in D1110 will be the present value of AD0. D1111 Digital average of analog input channel 1 (AD1) If the value in D1062 is 1, the value in D1111 will be the present value of AD1. D1115 (Latching device) Setting an analog input mode Default value: HFFFF： Bit 0~3: AD0 Bit 4~7 : AD1 Analog input modes: 0x0: Voltage mode (0 V~+10 V) 0x1: Current mode (0 mA~+20 mA) 0xF: Disabled Bit 15~8 Bit 7~4 Bit 3~0 D1115 Reserved AD1 AD0 D1118 Analog-to-digital conversion time Unit: ms Not a latching device Default value: K5 Reserved AD1 AD0
