Control Relays
When "Use data register for setting parameters" is enabled, internal relays can be set as control relays.
3 bits are used starting from the internal relay that was set, and each bit has the following function.
Notes:
•
Starting internal relay a0: Read parameters
When changed from off to on, the analog module setting values are read into the operation setting data registers.
•
Starting internal relay a1: Read initial parameter values
When changed from off to on, the initial values (the parameters that were saved when the user program download was executed) are
read into the operation setting data registers.
•
Starting internal relay a2: Write operation setting parameters
When changed from off to on, the data stored in the data registers is written to the analog module as the parameters.
•
After a control relay is changed from off to on, it automatically turns off.
•
If all of the control relays are changed from off to on in the same scan, they are executed in +0, +1, +2 order, and the analog module is set
with the initial values.
