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
