Changing to CS1W/CJ1W-NC271/471/F71 from CS1W/CJ1W-NC113/133/213/233/413/433
Appendix E
Operating Memory Area
In the CS1W/CJ1W-NC271/471/F71 PCU, the Operating Memory Area allocations and functions have
changed, as shown in the following table.
A comparison of the functions of these words is provided in the following table. The differences between the
functions, such as in axis operations executed by the Operating Memory Area words, are explained later in this
appendix.
Operating Memory Area words for CS1W/CJ1W-NC113/133/213/233/413/433 PCUs are shown in the follow-
ing table as those for the X axis of the CS1W/CJ1W-NC113 PCU, and the beginning word n is calculated using
the following equation.
n = 2000 + (unit number
×
10)
The Operating Memory Area words for CS1W/CJ1W-NC271/471/F71 PCUs are calculated for each axis using
the following equation.
a = Beginning word of Axis Operating Output Memory Areas specified in Common Para (Axis
No.
