Communicating with IB Series

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 comparator values (P.V. values) from sensor amplifiers" (Page 3-20)

For the message communication method, refer to "Message communication"

(Page 3-4).

Reading an output from a sensor amplifier

Available outputs: HIGH, LOW, GO, and check output

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.
