Programming Function Blocks and Features
CEMS Block Average
Outputs a block mean average CVn OV over the specified Average Period. The average is calculated from
input samples taken at equally spaced Sample Periods. All samples are discarded at the end of the Average
Period and the Average Period begins again.
Samples are ignored when Calibrate Hold is ON(1). After the Average Period the new average is calculated
using only the samples taken before and after the Hold. If no valid samples are taken, the output maintains
its previous value.
Table 4-48 describes the CEMS Block Average prompts. See Table 4-2 for additional prompts.
