16-72 Counter A
Range: Function:
0 N/A* [-2147483648 - 2147483647 N/A] View the present value of Counter A. Counters are useful as comparator operands, see
par. 13-10
Comparator Operand .
The value can be reset or changed either via digital inputs (parameter group 5-1*) or by using an
SLC action (par. 13-52
SL Controller Action ).
16-73 Counter B
Range: Function:
0 N/A* [-2147483648 - 2147483647 N/A] View the present value of Counter B. Counters are useful as comparator operands
(par. 13-10
Comparator Operand ).
The value can be reset or changed either via digital inputs (parameter group 5-1*) or by using an
SLC action (par. 13-52
SL Controller Action ).
16-75 Analog In X30/11
Range: Function:
0.000 N/A* [-20.000 - 20.000 N/A] View the actual value at input X30/11 of MCB 101.
16-76 Analog In X30/12
Range: Function:
0.000 N/A* [-20.000 - 20.000 N/A] View the actual value at input X30/12 of MCB 101.
16-77 Analog Out X30/8 [mA]
Range: Function:
0.000 N/A* [0.000 - 30.000 N/A] View the actual value at input X30/8 in mA.
3.16.8 16-8* Fieldbus & FC Port
Parameters for reporting the BUS references and control words.
16-80 Fieldbus CTW 1
Range: Function:
0 N/A* [0 - 65535 N/A] View the two-byte Control word (CTW) received from the Bus-Master. Interpretation of the Control
word depends on the fieldbus option installed and the Control word profile selected in
par. 8-10
Control Profile .
For more information please refer to the relevant fieldbus manual.
16-82 Fieldbus REF 1
Range: Function:
0 N/A* [-200 - 200 N/A] View the two-byte word sent with the control word form the Bus-Master to set the reference value.
For more information please refer to the relevant fieldbus manual.
16-84 Comm. Option STW
Range: Function:
0 N/A* [0 - 65535 N/A] View the extended fieldbus comm. option status word.
For more information please refer to the relevant fieldbus manual.
16-85 FC Port CTW 1
Range: Function:
0 N/A* [0 - 65535 N/A] View the two-byte Control word (CTW) received from the Bus-Master. Interpretation of the control
word depends on the fieldbus option installed and the Control word profile selected in
par. 8-10
Control Profile .
