Setting the I/O Size
For slaves in which the I/O size can be changed by switches, or by tools other than
the CX-Integrator, the CX-Integrator cannot be used to confirm that the I/O size is
correct.
For these slaves, use the following procedure to directly input the I/O size.
1. Select the desired slave, then select
View - Property .
2. Click the I/O Information Tab.
3. Click the Edit Button. The Edit I/O Size Dialog Box will be displayed.
4. Input the correct I/O size for each connection. If the connection is not known, input
the correct I/O size in the Poll settings.
5. Click the OK Button.
