The following describes how the scanner cyclically communicates with the DL-EP1
(cyclic communication).
"Reading an output from a sensor amplifier" (Page 3-18)
"Entering an external input to a sensor amplifier" (Page 3-19)
"Reading judgment values (P.V. values) from sensor amplifiers" (Page 3-20)
For the message communication method, refer to
Reading an output from a sensor amplifier
Available outputs: HI, LO, GO, and alarm output
Device assignments:
"Monitor Data (84 Words (168 Bytes)) Assembly Instance
(Instance ID): 64H" (Page 3-9)
This example shows how to read the HI output from the sensor amplifier ID01.
(1)The output from the sensor amplifier entered into the IN area via cyclic
communication.
