This operation uses a get or put type and a stat type. The user must keep in mind that command types link, get, and put involve transferring data over a network which means that the user must check that the network operation has successfully completed. The user must keep in mind that both the process variable in an IOC and the tcl linked variable can change at any time and are only synchronized only during a get or put type command. Use of lists is encouraged in link, get, put and mon types to improve the efficiency of the network communications. When checking the state, status, severity, and time in scripts, it is usually easier to use the stat command type.
Info works well for interactive use.
The put and putw command types require notification from the IOC that the record has processed before completion. It is much better to rely on readback process variables to ensure that a put operation has successfully completed. With a readback available use of putq is preferred. The putq does not require IOC notification before completing. When using asynchronous forms of link, get and put, the application must give the X-event loop time to process before each check on completion.
