The data of S

1 

is compared to the data of S

2

. The

result is indicated by 3 bit devices specified from
the head address entered as D. The bit devices
indicate:
S

2 

is less than S

1 

- bit device D is ON 

S

2 

is equal to S

1 

- bit device D

+1 

is ON

S

2 

is greater than S

1 

- bit device D

+2 

is ON

The operation is the same as the CMP instruction
except a single data value (S

3

) is compared against

a data range (S

1

-S

2

). 

S

3 

is less than S

1

and S

2

- bit device D is ON

S

3 

is equal to or between S

1 

and S

2 

- bit device D

+1

is ON
S

3 

is greater than both S

1 

and S

2 

- bit device D

+2 

is

ON

CMP

(Compare)

Compares two

data values -

results of <, = and

> are given.

K, H,

KnX, KnY, KnM, KnS,

T, C, D, V, Z

Note:

3 consecutive

devices are

used.

ZCP

FNC 11

(Zone

compare)

Compares a data
value against a
data range -
results of <, = and
> are given.

K, H,

KnX, KnY, KnM, KnS,

T, C, D, V, Z

Note: 

S

1

 should be less than S

2

Y, M, S

Note:

3 consecutive

devices are

used.

Note: The destination (D) device statuses will be kept even if the CMP instruction is
deactivated. Full algebraic comparisons are used, i.e. -10 is smaller than +2 etc.
