- EtherNet/IP Compatible Network Unit DL-EP1 User’s Manual (GT2) -
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
comparator values (P.V. values) of the respective instances using a service makes it
possible to read the comparator values (P.V. values) of the sensor amplifiers
corresponding to the respective instances.
