For example, if you expand MBTCP.DATA, you see that it contains two UDTs,

ReadData and WriteData. Both of these are 600-element integer arrays by

default.

Notice that these UDTs are the data types used to declare the

MBTCP.DATA.ReadData and MBTCP.DATA.WriteData controller tag arrays.

The UDTs are commented in the DESCRIPTION column.

Tip: If more than 600 words of Read or Write Data are needed, the MBTCP.DATA.ReadData and

MBTCP.DATA.WriteData controller tag arrays can be expanded. Simply edit the size of the

ReadData or WriteData integer array in the Data Type column of the MBTCPDATA UDT. In the

example below, the ReadData array size has been changed to 2000. Save and download the

ladder program for this change to take effect.
