CHAPTER 9 DEDICATED INSTRUCTIONS

9.18 Z(P).UINI (Station No. Setting of Own Station)
(2) Control data
*1 The setting side is as shown below.
User: Before execution of the link dedicated instruction, data must be set by the user.
System: The CPU module stores the execution result of the link dedicated instruction.
The UINI instruction can be executed only once.
Once a station No. has been set up, the UINI instruction cannot be executed again. (Doing so will result in error completion.)
In the case of error completion of the UINI instruction, take corrective actions against the error and execute the UINI
instruction again.
Modules are initialized by executing the UINI instruction.
Therefore, cable disconnection is detected in adjacent stations. This may increase IN-side cable disconnection detection
counts (SW0074) or OUT-side cable disconnection detection counts (SW0084).
