Allocation of logic inputs for input pins of X19
The source (input pin on X19) from which the respective logic input is to be read is
specified via parameters P156, P157 and P158. Inputs which are not read by an
input pin on X19 can be allocated a fixed "0" or "1 (this is not, of course, applicable
for all inputs). The parameters are 24 bits large with 4 bits defined per logic input.
This allocation can be easily done with the assistance of the ServoManager.
With direct access via RS232, a terminal or a fieldbus, the following table can be
used for setting the parameters.
