Select condition
(vii)
Figure 4.2-13 shows the select condition logic in the DPSY01 function. The DPSY01 function
checks the condition for the select command using the signal "DPSY01_3PH_STATE" (See
Table 4.2-34). If the original logic does not meet with the requirements of the user, the following
alternatives are available:
1. The user can replace the original logic with alternative logic.
2. The user can add additional logic to the original logic.
How to replace the original logic
If the user wishes to replace the select condition logic completely, the user can replace it using
the PLC connection point "User Configurable Condition".
1.
Connect the user-customized logic using "DPSY01IN_TMP_32", which is listed as
PLC#2 in Table 4.2-8.
2.
Set the scheme switch [DPSY01-LGSLFFCT] to PLC.
How to add another select condition signal
If adding another condition is required, the user can add a signal to the select condition logic
using the PLC condition point "User Additional Condition".
1.
Add a user-preferred signal using "DPSY01IN_TMP_31", which is listed as PLC#1 in
Table 4.2-8.
2.
Set the scheme switch [DPSY01-LGSLFFCT] to Fixedlogic.
