The port on the CIF Unit is restarted to prepare to send or receive data. You use the Restart Port control
command in the Output Data Type object to restart a port. Refer to A-3 List of NX Objects on page
A-5
for details on each object.
This programming sample is for the example given in 7-4-5 Example of Control Co
mmand Execution on
page 7-23. The processes in the table in 7-4-5 Example of Control Command Execution on
page 7-23
correspond to the CASE statements in the ST program as follows:
The following variable table is set from the Support Softwar
