- EtherNet/IP Compatible Network Unit DL-EP1 User’s Manual (FD-MH) -
Reading the current value (instantaneous flow rate) of the sensor
amplifier
The current value (instantaneous flow rate) is read from the IN area to which the ID
number of each sensor amplifier is assigned.
Device assignments: "Monitor Data (84 Words (168 Bytes)) Assembly Instance
(Instance ID): 64H" (Page 3-9)
This example shows how to read the current value from the sensor amplifiers ID01,
ID02, and ID03.
(1)When the current value of a sensor amplifier is updated, the new comparator
value is entered into the IN area via cyclic communication.
* If the current value is over range, under range, or invalid, the previous value is
retained without updating the current value. Use the value with the current value
property.
(2)The property of the current value is entered. If the current value is "over (FFFF)" or
"invalid (----)", the bit corresponding to the ID number of the appropriate sensor
amplifier is set to 1.
* For the FD-MH Series, the current value (instantaneous flow rate) is stored in the
current value 0.
