N1 : Add "4" at setting time
N2 : Add "10" at setting step No.
N3 : Add "8" at setting program name

+18 (total number of T, ST and C points)/16))
M : Internal relay
V : Edge relay
D : Data register
T : Timer
ST : Retentive timer
C : Counter
* 1 : 136 is the default value. (It can be increased or decreased by parameter setting.)
* 2 : Round up "number of bit device points/16" to the right of the decimal point.
Refer to Section 5.4.4 for the memory capacity calculation example.
