17.8 ZP.UINI
17.8.3 Functions
(1) This instruction changes the transmission specifications, communication
protocol and host station No. of each channel of the Q series C24 specified by
Un.
(2) Execution of the UINI instruction changes the following buffer memory
settings to enable communication with the new settings.
The UINI instruction can change the following settings that cannot be changed by mode switching that uses the mode
switching request signal (Y2/Y9).
● Station No. setting change
● Switching to synchronous operation or switching from synchronous operation to the other mode (independent operation)
(3) Whether the UINI instruction was completed normally or abnormally can be
checked with the completion device (D) or status display device at completion
((D)+1).
(a) Completion device
Turns on at the END processing of the scan where the UINI instruction is completed, and turns off at the next
END processing.
(b) Status display device at completion
Turns on and off depending on the completion status of the UINI instruction.
• Normal completion: Stays off and does not change.
• Abnormal completion: Turns on at the END processing of the scan where the UINI instruction is
completed, and turns off at the next END processing.
