How to Display Different Control Bits Within Elements
With a data file address displayed, you may use the [ ,1& ] and [ '(& ]
keys to display different bits within a Timer, Counter, or Control
word, or change bit addresses within a Bit element.
When a Timer, Counter, and Control address is displayed, the [ ,1& ]
and [ '(& ] keys work as follows:
1. To view the Control bits in T4:3, display the address as
previously described. The display shows the highest numbered
Control bit, with the address on the top left and the bit function
and on/off state in the lower right-hand corner:
Press >'(&@
2. The LCD displays the original bit and the next lower numbered
bit. The bit address in the upper left-hand corner corresponds to
the function and state in the lower right-hand corner:
Press [ '(& ].
3. The display shows the next lowest bit in the Control word:
The [ '(& ] key works in the same fashion.
A maximum of three Control bits may be displayed at one time. Only
the Control bit displayed in the lower right-hand corner can be
manipulated. Use the [
,1& ] and [ '(& ] keys to access any other bits.
Another function of the [ ,1& ] and [ '(& ] keys is to change the Bit
address displayed on the LCD.
When a Bit file address is displayed at the bit level, the [ ,1& ] and
[ '(& ] keys work as follows:
T4:3.0/15
EN =0
T4:3.0/14
EN =0 TT = 0
T4:3.0/13
EN =0 TT = 0 DN = 1
