How the Bit Status field functions when Entry Allowed is selected:

Assume the results of example one, the field is currently displaying

[STOP]

. Further assume you use the

Select

key

on the 2800 to assign focus to this field then press the

Enter

key.

Drive Value

0000 0000 0000 0001

AND with compliment of Mask Value

1111 1111 1111 1110

Formula 1

write this value to the Drive

0000 0000 0000 0000

2800 reads Drive Value back

0000 0000 0000 0000

2800 ANDs it with Mask Value

0000 0000 0000 0001

Results

0000 0000 0000 0000

Result does not match Data Value so the field text will change to

[START]

Lets try the opposite case. Assume the results of example two, the field is currently displaying

[START]

. You use

the

Select

key on the 2800 to assign focus to this field then press the

Enter

key.

Assumed PLC Value

0000 0000 0000 0000

AND with compliment of Mask Value

1111 1111 1111 1110

Formula 2

Results

0000 0000 0000 0000

OR with Data Value

0000 0000 0000 0001

write this value to the PLC

0000 0000 0000 0001

2800 reads PLC Value back

0000 0000 0000 0001

2800 ANDs it with Mask Value

0000 0000 0000 0001

Results

0000 0000 0000 0001

Result does match Data Value so the field text will change to

[STOP]
