3.3 Numbering and Function of External Input/Output Contacts [X] / [Y]
îš„ Input relay X0 ~ X377
The numbering of input relay (or input terminal) is in octal format. DVP-PM is designed for up to 256 points, and
the range is: X0 ~ X7, X10 ~ X17, ...X370 ~ X377.
îš„ Output relay Y0 ~ Y377
The 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.
îš„ Function of input contact X
The input contact X is connected to input devices and reads the input signals into DVP-PM. There is no limitation
on the times of using NO (Normally Open) / NC (Normally Closed) contacts in the program. ON/OFF of the input
contact X only changes with ON/OFF status of the connected devices. PMSoft can not force ON/OFF the input
contact X.
îš„ M1304, Force ON/OFF contact X
When M1304 = OFF, input contact can not be force ON/OFF by PMSoft; when M1304 = ON, input contact X can
be force ON/OFF by PMSoft. However, the function of updating input signals will be disabled in this case.
îš„ Function of output contact Y
Output contact Y sends out ON/OFF signals to drive the load connected to output contacts. There are two types
of output contacts, relay and transistor. There is no limitation on the times of using Y contacts (NO / NC) in the
program. However, we suggest users do not repeat the No. of output coil Y; otherwise, according to the scan
principle of ladder diagram, the status of output coil will be determined by the status of the last Y in the program.

Y0 is repeated.
The output of Y0 will be determined by Y0 in
2
, i.e. ON/OFF of X10
will determine the output status of Y0.
