Parameter setting example of polling I/O communication
An example of how to set each parameter for polling of the following data is shown.
•
Measured data items:
Alarm state, RUN/STOP state, Measured value (PV),
Manipulated output value (MV1) monitor
•
Setting data items:
Setting state selection, RUN/STOP transfer, Set value (SV),
Event 1 set value
•
Number of communication controllers:
3 controllers
•
Number of communication words:
11 words * (IN), 11 words * (OUT)
* 2 (Number of communication data items)
×
3 (Number of communication controllers) +
5 (Fixed communication data, five words)
•
Controller address:
1 to 3 (Address of controller 1 to controller 3)
•
Automatic acquisition of controller address:
0 (Do not execute the automatic acquisition)
Fixed five communication data words are assigned to the measured data items of “Alarm
state” and “RUN/STOP state.” In addition, fixed five communication data words are assigned
to the setting data items of “Setting state selection” and “RUN/STOP transfer.”
When the number of communication words is set via Explicit message communication, or by
the configuration tool or rotary switch, the value set by the DIP switch may be ignored.
Conduct parameter set according to the procedure described below.
1.
Set measured data items (IN) with a parameter setting screen of COM-JH.
•
Set attribute ID “1” of “Measured value (PV)” in “IN ch1 (Parameter 1).”
•
Set attribute ID “14” of “Manipulated output value (MV1) monitor” in “IN ch2 (Parameter 2).”
•
“0” is set to unused IN ch (Parameter 3 to 32).
In addition to “Alarm state” and “RUN/STOP state” assigned as fixed, up to 32 types of
measured data items can be selected.
