11 PROCESS CONTROL INSTRUCTIONS
11.2 I/O Control Instructions
The variation rate alarm counter is calculated using the following expression.
Set CTIM and
T so that the variation rate alarm counter (m)
2.
No processing is performed when variation rate alarm counter (m) = 0.
Ex.
When variation rate alarm counter (m) = 4, operations are performed as shown below.
■
Output conversion processing (3)
In output conversion processing, the following operations are performed and the result is stored in output 1 (BW1)/output 2
(BW2).
