AF

Advanced

function

selection

AF is used to select advanced function.    The value of AF
is calculated as below:
AF=Ax1 + Bx2 + Cx4 + Dx8 + Ex16

A=0, Slow cyclic display;
A=1, Fast cyclic display.
Above  setting  only  affects  display  and  has  no  effect  on
internal scan speed and alarm response time.
B=0, RTD input use two-wire wiring;
B=1, RTD input use three-wire wiring.
C=0, Only channel 2 is retransmitted to COMM port;
C=1,  All  input  channels  are  cyclically  retransmitted,  and
the retransmission time interval on every channel is about
3 seconds.    The output ranges of all channels are defined
by dIL2 and dIH2.
D=0, Normal;
D=1, All low limit alarms are changed to high limit alarm.
E=0, Normal;
E=1, Set M2(MIO) and M3(OUPT) support single channel
input only.

For  example,  to  set  a  AI-702M  with  2  inputs,  fast  cyclic
display,  channel  1  input  from  three-wire  RTD  (J0  module
on  M1  socket),  channel  2  input  from  thermocouple  (J1
module on M2 socket), current retransmission of channel
2  outputted  to  COMM  port,  the  AF  parameter  should  be
set as below:
A=1,B=1,C=0,D=0, then AF=19.

0~31

nonc

NO/NC

selection

Single  channel  relay  module  provides  both  normal  open
and  normal  close  output,  while  dual  relay  output  module
only provides NO output.
If L5 dual relay installed, set nonc=0, all in NO status, set
nonc=127, all in NC status.

However, by parameter “nonc”, the NO output can

be

changed to NC output.
nonc = Ax1 + Bx2 + Cx4 + Dx8 + Ex16 + Fx32 + Gx64
A,B,C,D,E,F,G  respectively  set  NO/NC  output  of  OP1,
OP2,  AL1,  AL2,  AU1,  AU2  and  MIO.    0  means  the
corresponding output is NO, and 1 means NC output.

0 ~63, 127

OPn

Select the

channel to be

retransmitted

OPn=0, OUTP port is for alarm output.
OPn=1~4,  OUTP  port  is  used  for  retransmission  of
channel OPn.
OPn=7,  Re-transmit  the  minimum  value,  among  all
channels (defined by Cn) to OUTP
OPn=8,  Re-transmit  the  maximum  value,  among  all
channels (defined by Cn) to OUTP

0~4, 7~8
