■ Set Values
• If the set value contains a decimal point, omit the decimal point and set
the value.
Example:100.0
→ 1000 or 03E8H: set value
• When changing set values, always set a new value within the setting
range. The set value will not be changed if a value outside the range is
set.
Operation Commands When the EJ1 confirms that the Operation Command Request Bits have been
set by the PLC, the EJ1 reads the operation command code set in PLC mem-
ory and accepts the operation command.
To execute an operation command, set the operation command code in the
PLC memory words corresponding to the Programless Download Settings
and then set the Operation Command Request Bits.
Note Refer to 5-1-5 Operation Command Codes for Programless Com-
munications for information on operation command codes.
• Single Operation Command
Operation commands are accepted only once.
