Programless Communications
Section 5-6
• Multi Action
Operation of writing any parameters in the download area settings that
have changed from the previous values is performed continuously.
• Stop Operation
Operation is stopped after a series of operations has been completed.
Note (1) Always set the Setting Change Request Bits last. If the Setting
Change Request Bits are set before the set value is changed, an
unexpected value will be written.
(2) All programless download parameters will be updated when the
Setting Change Request Bits are set. If set values are not the
same in EJ1G and PLC memory, e.g., when the power is turned
ON or the bank is changed, always change the values in PLC
memory first and then set the Setting Change Request Bits.
