RTE maps input_w and output_w up to 256 by default. If you want to perform, e.g., from the RDE I/O panel, forcing on unmapped units (typical example are the INP_W and OUT_W associated with remote units on fieldbus) you must use this command to map the memory.
Both SHELL commands(FV, RV) that can be used by the RDE shell and device commands(F_INP and associates) that can be used not only by SHELL but also by STP files are available to perform forcing.

baseIO |
Index base |
nWordIn |
Number of input words to be mapped to input |
nWordOut |
Number of output_words to be mapped to output |
Notes |
Since it is a device command it can be included in STP files(autoexec.stp etc...) |
NOTE: For RTE versions < 33.18.xx the unit of nWordIn and nWordOut was in bytes instead of words.
