3-4 Message Communication

3-26

Communicating with the SK-1000 Series

Message communication uses objects and services to send and receive data.

Executing a service (1) for a DL-EP1 object enables data read (2), parameter

change (3), specified operation execution (4), and read of the number of decimal

places (5), etc.

Taking DL Object as an example, one instance is provided for each of the sensor

amplifiers connected to the DL-EP1. Reading the attributes corresponding to the

judgment values (P.V. values) of the respective instances using a service makes it

possible to read the judgment values (P.V. values) of the sensor amplifiers

corresponding to the respective instances.
