Please follow the procedures below to operate the test:
※ Usually the default delay response time is not necessary to change, except that:
When the communication mistake is caused by the signal collision in the circuit, try to extend the delay response
time.

Application Example
In this example, a computer uses its USB port to connect with an USB to RS-485 converter to transfer the
communication signal to the RS-485 interface. Then, the RS-485 is connected to two VS series PLC’s CP1 those
station numbers are assigned to #1 and #2. After that, executes the Ladder Master S programming software on the
computer to connect with the station #1 and station #2 PLCs for to read the project, control STOP/RUN and
monitor those PLCs.
Use the Ladder Master S to set the CP1's parameters of PLC Station #1 and compile relevant program. Then,
connect to the USB programming port of Station #1 and write the project into the PLC Station #1.
Set the application type:
VS Computer Link Slave
Set the baud rate:
19200 bps
Set the station No.:
Station #1
The program writes to the PLC
Station #1.
By the USB programming port, the project is written into the PLC
Station #1
PLC Station #1
