2-17 Special Function Module
The VS Series PLC offers various Special Function Models, such as analog input/output and temperature input. The
following is the list of selectable special models.

Module
All the Special and DIO Expansion Modules are serial connected on the right side of the Main Unit. The connecting
st.
sequence is without reserve. The closest Special Module is designated as the 1 Special Module. Then on its right
nd.
side, the following Special Module is the 2 , and so on. But, the DIO Expansion Module or Power Module will not
interfere to the ranking. Please pay attention to the power consumption, appropriately add the VS-PSD power repeater
module is required as the picture below if the power is insufcient.
There are some Buffer Memories (BFM) built-in at every Special Function Module to store the related data.
The VS series Main Unit uses the FROM/TO instruction to read/write the data in the module's BFM thus can achieve the
purpose of data transfer across each other. The FROM instruction is used to read BFMs data from the designated
special module. The TO instruction is used to write data into the designated BFMs at the special module. For detailed
information about the FROM and TO instructions, please refer to the following pages.
Furthermore, can directly use the addressing operation to easily access the data in the special module's BFM.

Above is the example table of Operand devices for an instruction. The device type of UnG at the table is to indicate
the BFM at a Special Module could be used by the instruction directly. Thus, if the operand U1G3 is used in an
st.
instruction, that means to access the data at the BFM #3 of the 1 Special Module.
st.
The program line below is to equally compare the data in the BFM #30 of the 1 Special Module with the constant
value K201, and the comparison result is used to drive the coil of M0.
If the content value of U1G30 is equal to K201, the M0 will be turned ON. Due to the monitor mode of the Ladder
Master S that could not get the value from the U1G30, the in-line comparison symbol in the ladder diagram will not
show the ON result; but, the real output of the program line will not be affected by the display.
nd.
The program line below is to move the value H1100 into the BFM #0 of the 2 Special Module.

Since the Ladder Master S programming software can not get the real time status from a BFM of Special Module, it is
unavailable to monitor the data of operand at the UnG that is used in the instruction.
