8.6.1.1 Digital inputs and outputs for COMPAX 1000SL

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.
