Function Code 8 – Rate Limiter
GENERAL DESCRIPTION
The output of this block equals the input until the input rate of change exceeds the limit
value (S3 and S4). When the rate of change of the input is greater than the limit, the
output changes at the rate established by the limit until the output equals the input.
UTILIZATION
The MOD 30ML/MODCELL compound FC9 used here has a group of EX function
blocks (Expression block) to perform rate limiting.
Figure 8 .1.
Function Code 7
The Expression block RATELIM has an input called S1. The input for which the rate
limiting is required is connected to this. The result of the EX block RATELIM is the final
result. The S2 input of this block can be connected to a track signal enable switch. When
FALSE, the output of the rate limiter is same as the input.
In the EX block FC7, enter the constant S2 in floating point units. The final result is the
square root of S1 scaled by S1.
