‘Data communications input’ can be programmed with keys when the ‘Math function’ (option) and ‘Communications interface’ (option) are combined. However, for the option of ‘Communications interface’, it is programmed through communications only.

[1] Math functions

The measured data of each channel can be computed and their results are displayed and printed. The alarm setpoints in the channel Nos. for computed results are programmed for the computed values.

2. Programming

2.1 Printing channel for computed result

1) Math functions of which computed results are only printed in the channels Nos. of measured value The computed result by the math functions of square root, natural logarithm, logarithm, absolute value, and exponential is only printed in the channel No. of measured value (x). Therefore the measured value (x), which these 5 math functions are applied to, cannot be printed.

2) Math functions of which computed results can be printed in any channels The computed result by other math functions than the above 5 kinds can be printed in any channels including the channel of measured value. However, if the channel of measured value is selected, the measured value cannot be printed.

2.2 Printing range

The printing range of the channel for computed result is “Printing range” programmed by math function programming, not by range programming.

2.3 Decimal place for display and printing

The decimal place is decided by “Printing range” programmed by math function programming. If the decimal place differs in the maximum and minimum values, the fewer decimal places is effective.

2.4 Computation of maximum, minimum and average values

1) Resetting of computation The computation is automatically reset after the programmed interval time. Accordingly maximum, minimum and average values in each interval time are computed.

2) Operation at power failure recovery

1. If the power is recovered in the programmed interval time, the computation continues.

2. If the power is not recovered in the programmed interval time, the computation is canceled and starts again

from the recovery time.

3. The judgment of power failure is within 24 hours. If the power failure continues longer than 24 hours, the

computation is canceled irrespective the recovery time and starts again from the recovery time.

3) Starting time of computation The starting time is only valid for the first operation after its setting. The computation starts from the starting time.

‘x’ and ‘y’ channels

If the measured value of ‘x’ channel or ‘y’ channel is not used, make sure to program any channel number to the channel not used as a dummy input. (No programming of the channel not used will become an error.) Then program the appropriate constants to ‘0’.

‘x’ and ‘y’ channels are blank.
