31.4 Using FLEX NETWORK External I/O

By connecting the FLEX NETWORK unit to the display unit, you can use the display unit to control remotely located external I/O. In addition, you can control other things besides inputs and outputs. You can also add multiple FLEX NETWORK units to increase the number of I/O points.

There are two connection lines for the unit and the same communication data is output to both.

When you use either line both line 1 and line 2 are available. The maximum number of connectable I/O unit stations is 31 when you are using one line. When you are using two lines, the maximum number of connectable stations is 63. One line will support 31 and the other line will support 32.

For details on configuration, refer to Section 1.1 System Configurations in the "FLEX NETWORK Users Manual".

31.4.1 Procedure - Using FLEX NETWORK External I/O

FLEX NETWORK Units: Models and Number of Stations

The following describes the type, number of points, and number of stations for FLEX NETWORK units.

For example, if you use an I/O unit with 32 discrete inputs and 32 discrete outputs for a total of 64 points, and define S-No.1, then the I/O unit will use station number 1 to 4.
