27 UPCOUNT
Upcounts the pulses and then output the value- UPCOUNT(A, B, C).
After receiving a trigger input (A), outputs are upcounted by C conditions. If
the B inputs is 1, do not operate and display 0. If the B inputs is 0, operate.
If the C parameter is 0, upcount when the input at A changes from 0 to 1.
If the C parameter is 1, upcount when the input at A is changed from 1 to 0.
If the C parameter is 2, upcount whenever the input at A changes.
Output range is: 0–32767
28 DOWNCOUNT
Downcounts the pulses and then output the value- DOWNCOUNT(A, B, C).
After receiving a trigger input (A), outputs are downcounted by C
conditions. If the B input is 1, do not operate and display the initial value of
C. If the B input is 0, operate.
Downcounts when the A parameter changes from 0 to 1.
The Pl process block (Pl_PROCESS Block) must be used after the PI control block (PI_CONTROL Block)
for proper Pl control operation. Pl control operation cannot be performed if there is another block
between the two blocks, or if the blocks are placed in an incorrect order.
User sequence features work only with code version 1.00, IO S/W version 0.11, and keypad S/W version
1.07 or higher versions.
