D.4.2 Devices Functions

The Function of Input/output Contacts

The function of input contact X: input contact X reads input signal and enter PLC by
connecting with input equipment. It is unlimited usage times for A contact or B contact of
each input contact X in program. The On/Off of input contact X can be changed with the
On/Off of input equipment but can't be changed by using peripheral equipment (WPLSoft).

The Function of Output Contact Y

The mission of output contact Y is to drive the load that connects to output contact Y by
sending On/Off signal. There are two kinds of output contact: one is relay and the other is
transistor. It is unlimited usage times for A or B contact of each output contact Y in program.
But there is number for output coil Y and it is recommended to use one time in program.
Otherwise, the output result will be decided by the circuit of last output Y with PLC program
scan method.
