During 32-bit load and store commands user should use only 0 to 84 16-bit memory locations.
Example 6.
This application can be used to monitor feedback on FSV and convert it to other quantity by
the use of PLC and display on Display Panel to monitor up to certain limit and give trip
(External Fault).
Program Code:
Input from Display Panel into P101 to PA01.
P101 016094108000
Multiplication between Register 94 and 108 and result will be stored
in 32-bit memory location.
P102 001001000100 Copy 16-bit Immediate value (100) into Register no.1
P103 018001000000 Division between 32-bit memory location and register 1 and result
will be stored in 32-bit memory location
P104 003010000000 The value of 32-
bit memory location is stored in Register 10 as high
and register 11 as low 16-bit value.
P105 028012010011 Word OR logic between Register 10 and 11 and result will be store
in Register 12.
P106 061001012000 Display Register 12 in PLC Display Number 1.
P107 035001012102 If Register 12 is greater than Register 102 then Flag number 1 will
be set
P108 048012001000
Status of flag 1 will be written to
option of PSI's
selectable options.
P109 000000000000 End of Program.
User has to set following parameter.
1. Enable PLC function from C312.
2. Register 94 contains FSV input, which is read only memory location.
3. Register 108 contains value of Panel Para8 (C708) which is used for multiplication factor,
and that should be change as per input quantity range.
Note: There is only one 32-bit memory location is given.
During 32-bit load and store commands user should use only 0 to 84 16-bit memory locations.
