- EtherNet/IP Compatible Network Unit DL-EP1 User’s Manual (GT2) -
The following describes how the scanner cyclically communicates with the DL-EP1
(cyclic communication).
"Reading an output from a sensor amplifier" (Page 3-17)
"Entering an external input to a sensor amplifier" (Page 3-18)
"Reading comparator values (P.V. values) from sensor amplifiers" (Page 3-19)
For the message communication method, refer to
Reading an output from a sensor amplifier
Available outputs: HIGH, LOW, GO, HH, and LL
Device assignments:
"Monitor Data (84 Words (168 Bytes)) Assembly Instance
(Instance ID): 64H" (Page 3-9)
This example shows how to read the HIGH output from the sensor amplifier ID01.
(1)The output from the sensor amplifier entered into the IN area via cyclic
communication.
To use the HH output and LL output, set "Special Output Setting" of the
sensor amplifier to "5-Output".
