The MODBUS Slave
When the VS PLC’s communication port has been set to the application type of the “MODBUS Slave”, the
human-machine interface (HMI) or supervisory control and data acquisition system (SCADA) can access the
VS PLC’s data through the “MODBUS protocol”.

The communication application types supported by the VS series PLC are briey introduced below:
The VS Computer Link Slave (hereby referred to as the VS Slave)
When the VS PLC’s communication port has been set to the application type of the “VS Computer Link Slave”, the
human-machine interface (HMI) or supervisory control and data acquisition system (SCADA) can access the
VS PLC’s data through the “VS Computer Link protocol” (hereby referred to as the VS Protocol).

The VS Computer Link Master (hereby referred to as the VS Master)
When the VS PLC’s communication port has been set to the application type of the
“VS Computer Link Master”, it cooperates with the LINK instruction and a LINK communication table to
operate communication procedures. This Master links and communicates with Slaves through the
“VS Computer Link protocol” (hereby referred to as the VS Protocol).
The VB Computer Link Slave (hereby referred to as the VB Slave)
When the VS PLC’s communication port has been set to the application type of the
“VB Computer Link Slave”, the human-machine interface (HMI) or supervisory control and data
acquisition system (SCADA) can access the VS PLC’s data through the “VB Computer Link protocol”
(hereby referred to as the VB protocol).
