The rst item set in the table means that the Master reads the data D0~D9 from the Slave #1 and stores them at
the D0~D9 of the Master.
The second item set in the table means that the Master writes its data at D10~D14 to the D10~D14 of the Slave #1.
The third item set in the table means that the Master reads the data D0~D9 from the Slave #2 and stores them at
the D20~D29 of the Master.
The fourth item set in the table means that the Master writes its data at D30~D34 to the D10~D14 of the Slave #2.
The fth item set in the table means that the Master writes its data at D40~D59 to all the D40~D59 of the Slaves.
To set the Slave station #255 means that the Master writes the data to all of the Slaves. Note that Read Command
cannot be used in this application.
The last column of the table is for the Disable Contact. If that specied contact is “ON”, the communication item
set will be ignored. For example, if M1 = “ON”, the rst and second item sets in the table will skip. This is the new
function of the VS series, which can help designers effectively manage the operation of the communication table.
A communication item set does not need to specify a Disabled Contact (such as the fourth item set), so that the
command of the set does not have the disable control function.
Description
Lower 8 bits
Upper 8 bits
The record of the Slave's station number when the rst communication error is occurred
Instruction working status
0: Normal data transmitting / receiving
4: The error is caused by the assigned device is inappropriate
7: The error is caused by the communication command is incorrect
A: The communication setting is normal but no response from the Slave station
(Time-out occurs)
B: Abnormal communication
The LINK instruction will reset the D100 to be 0 before the rst item set at the table is executed.
If any communication error occurs during the execution of the instruction, a code will be recorded in D100. Only when
the content value of D100 is 0, the recording action can be executed. Therefor, when there are possibilities of several
errors, users can use the program to move out the content value of D100 then reset it to 0. This way allows the D100
to record the next error.
To edit a communication table
Use the Ladder Master S to set up a LINK communication table and through its interactive window can set up and
edit a communication table easily.
In the structure of VS Series PLC, the communication tables are a part of the project. When the programmer to copy
or access the project, those tables will be duplicated automatically with the program.
