DVP-PM is designed for up to 256 points, andthe range is: X0 ~ X7, X10 ~ X17, ...X370 ~ X377. Output relay Y0 ~ Y377The numbering of output relay (or output terminal) is in octal format. DVP-PM is designed for up to 256 points,and the range is: Y0 ~ Y7, Y10 ~ Y17, …Y370 ~ Y377. Function of input contact XThe input contact X is connected to input devices and reads the input signals into DVP-PM. There is no limitationon the times of using NO (Normally Open) / NC (Normally Closed) contacts in the program. ON/OFF of the inputcontact X only changes with ON/OFF status of the connected devices. PMSoft can not force ON/OFF the inputcontact X. M1304, Force ON/OFF contact XWhen M1304 = OFF, input contact can not be force ON/OFF by PMSoft; when M1304 = ON, input contact X canbe force ON/OFF by PMSoft. However, the function of updating input signals will be disabled in this case. Function of output contact YOutput contact Y sends out ON/OFF signals to drive the load connected to output contacts. There are two typesof output contacts, relay and transistor. There is no limitation on the times of using Y contacts (NO / NC) in theprogram. However, we suggest users do not repeat the No. of output coil Y; otherwise, according to the scanprinciple of ladder diagram, the status of output coil will be determined by the status of the last Y in the program.X0X10Y0Y012Y0 is repeated.The output of Y0 will be determined by Y0 in 2 , i.e. ON/OFF of X10will determine the output status of Y0.
