Mitsubishi Electric MELSEC iQ-R Series - Changing the Parameters of Specified Loop Number

1168
10 PID CONTROL INSTRUCTIONS
10.2 PID Control Instructions (Inexact Differential)
Changing the parameters of specified loop number
S(P).PIDPRMW
These instructions change the operation parameter of the specified loop number to the PID control data stored in the specified
device number and later.
■Execution condition
Setting data
■Description, range, data type
*1 When specifying setting data by using a label, define an array to secure enough operation area and specify an element of the array
label.
■Applicable devices
• [RnPCPU (redundant)] If these instructions are used in a program executed in both systems, there are restrictions on their operation in the standby system
when the redundant system is in backup mode. ( MELSEC iQ-R CPU Module User's Manual (Application))
