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).

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.
Axpert-Eazy AC Variable Frequency Drive
Description
Multiplication between Register 94 and 108 and result will be stored
in 32-bit memory location.
Copy 16-bit Immediate value (100) into Register no.1
Division between 32-bit memory location and register 1 and result
will be stored in 32-bit memory location
The value of 32-bit memory location is stored in Register 10 as high
and register 11 as low 16-bit value.
Word OR logic between Register 10 and 11 and result will be store
in Register 12.
Display Register 12 in PLC Display Number 1.
If Register 12 is greater than Register 102 then Flag number 1 will
be set
Status of flag 1 will be written to 12:EXT_FLT option of PSI's
selectable options.
End of Program.
