III-20.7 DIDO (digital input/output card)
Digital input/output card, plugs into modular options card C. The DIDO is used for configuration and parameter setting
of digital inputs/outputs DIDO. Function block calculation is fixed to once per time slot.
Digital inputs:
d1 if configured as an output: hardware output a
d2 if configured as an output: hardware output b
Digital outputs:
slotid
0 = correct module fitted
1 = wrong module fitted
z1
status of hardware input a; if configured as an output: the output value read back
z2
status of hardware input b; if configured as an output: the output value read back
Configuration Description Values Default
Inv_Ia
direct - HW input di1 direct at z1 0 0
inverse - HW input di1inverted at z1 1
Inv_Ib
direct - HW input di2 direct at z2 0 0
inverse - HW input di2 inverted at z2 1
Inv_
direct - d1 direct on HW output do1 0 0
inverse - d1 inverted at HW output do1 1
Inv_Ob
direct - d1 direct on HWoutput do1 0 0
inverse - d2 inverted on HW output do2 1
Mode_a
Input - only HW input d1 at z1 0 0
Output - d1 at HW output do1 with feedback at z1 1
Mode_b
Input - only HW input d2 at z2 0 0
Output - d2 at HW output do2 with feedback at z2 1
