3-2 DL-EP1 EtherNet/IP Communication Function

3-4

Communicating with IB Series

 Cyclic communication

This function sends and receives data between the scanner and DL-EP1 at the set

RPI (Requested Packet Interval). The function can exchange data such as the

sensor amplifier's output signals and comparator values and error status without

ladder programs.

Configurations such as RPI and data size for cyclic communication are set

on the scanner side.

In a network which has many connected devices, including EtherNet/IP

devices, a delay or packet loss could occur if a large load is constantly or

temporarily applied on the network. Verify the settings carefully before

operation.

 Message communication

Message communication can be used for applications which do not require a

punctuality like cyclic communication.

In message communication, various parameters, including data which can be

exchanged with cyclic communication, can be read and written. Functions specific

to sensors such as the sensor amplifier preset function can also be executed.
