If reading is performed without error, the following responses are stored.
An example of a program that transmits an Explicit message via the
DeviceNet wireless unit is given below.
In this example, an Explicit message is sent to the DRT1-232C to read data
received by the DRT1-232C in the system configuration shown below.
The IN area allocation for the DRT1-232C at the CS1 is shown below.
