7.2 System Configuration

Flex I/O DeviceNet adapter + 16-point input
The program described in this section is based on the system described below.
1) DN91 is set to station number 5, the first sensor is set to station number 1, and the second
remote I/O is set to station number 0.
2) Bit strobe communication
Polling communication is used between DN91 and the remote I/O.
3) Input data is assigned from X100 to X117 and output data is assigned from Y100 to Y10F.
Sensor : Inputs X100 to X117
Remote I/O : Inputs X100 to X117
: Outputs Y100 to Y10F
4) The communication status of each station is stored in M0 and M1.
5) If an error occurs, the error information is read to D500, the station number where the error
occurred to D501, and the error code to D502.
6) Message communication write attribute data is set in D30 to D39.
7) DN91 is mounted in slot 0 of the main base unit.
