Notes
------------------------------------------------------------------------------------------------------------
 You can enable/disable the external control function. When the external control function is
disabled, the input from the external control is not accepted, but the state output signal is output.
 We recommend that when the external control function is not used, the function is set to
disabled to avoid malfunctioning due to any exogenous noise.
 The external control input signal is ignored when the product is remote controlled via the
communication interface.
 The memory 1 and 2 inputs are the inputs for specifying the memory number. For No. 1 to No.
4 memory, specify the 2 bit memory number of the Basic Setting Memory in the Continuous
function, or of the Sequence Memory in the Sequence function, or of the Simulation Memory
in the Simulation function.
 When the memory recall input is changed from high to low, this loads the data of the Basic
Setting Memory in the Continuous function, or of the Sequence Memory in the Sequence
function, or of the Simulation Memory in the Simulation function which has the number
specified by the memory 1 and 2 inputs. For the Sequence and Simulation function, the
compile is also performed.
