5.2.9 BCD (FNC18)

Operation 1:

(Applicable to all units)

The binar

y

source data (S) is converted into an

equivalent BCD number and stored at the

destination device (D). If the converted BCD number

exceeds the operational ran

g

es of 0 to 9,999 (16 bit

operation) and 0 to 99,999,999 (32 bit operation) an error will occur.This instruction can be

used to output data directl

y

to a seven se

ment displa

y

.

Operation 2:

(Applicable units: FX

(2C)

)

This function is equivalent to FNC 118 EBCD Data

(S)is converted from ‘floatin

g

point’ format to

‘scientific format’ (D). This instruction requires

double word (32 bit) operation and data re

5.2.10 BIN (FNC 19)

Operation 1:

(Applicable to all units)

The BCD source data (S) is converted into an

equivalent binar

y

number and stored at the

destination device (D). If the source data is not

provided in a BCD format an error will occur. This instruction can be used to read in data

directl

y

from thumbwheel switches.

Operation 2:

(Applicable units: FX

(2C)

)

This function is equivalent to FNC 119 EBIN Data

(S) is converted from ‘scientific format’ to ‘floatin

g

point’ format (D). This instruction requires double

word (32 bit) operation and data re

g

isters as

devices (S)and (D)to operate correctl
