8.6.1.2 Free assignment of inputs and outputs
You can make the permanently assigned standard inputs I1 to I6 available for
assignment using parameter P221. Meaning:
Input Function without
SHIFT Function with SHIFT Valency
I1 (X8/1) SHIFT -
1 (Bit 1)
33
I2 (X8/2) Manual+ Find machine zero (MZ) 2 (Bit 2)
I3 (X8/3) Hand– Approach real zero (RZ) 4 (Bit 3)
I4 (X8/4) Quit Teach real zero 8 (Bit 4)
I5 (X8/5) START reserved 16 (Bit 5)
I6 (X8/6) STOP Break (breaks off data
record) 32 (Bit 6)
Each input is assigned a valency. Calculate the sum of the valencies of the
required free inputs and enter this in parameter P221.
Hand+ and Hand- should be possible via the inputs; I1, I4, I5 and I6 should be
freely available.
1 (I1) + 8 (I4) +16 (I5) +32 (I6) = 57
You will obtain this setting using P221 = 57.
Note that when I1 is freely assigned (SHIFT), you can no longer
perform any "Functions with shift" via the inputs!
You can directly cancel all input functions (apart from Hand+ and Hand-) as
commands using interfaces (RS232, bus system).
♦ The status outputs O1 to O6 can be freely assigned using parameter P225.
♦ Use P223 and P224 to assign the outputs of the OUTPUT WORD command of
the bus systems (Interbus-S, Profibus, CAN – Bus, ...).
♦ Use P245 and P246 to assign the outputs of the HEDA bus (COMPAX with IPM
via the option A1).
♦ Permanently assigned outputs of unit variants (COMPAX XX30, ...) cannot be
masked.
