Ethernet/Ip - Renesas R-IN32M3 User Manual

R-IN32M3 Module

EtherNet/IP

5.3.2
In addition to Table 5.1, EtherNet/IP has more detailed LED control guidelines. EtherNet/IP
communication requires two types of bi-color LED displays:
MS (module status indicator) and
NS (network status indicator).
Both indicators must be implemented separately from the R-IN32M3 Module and controlled
by the application controller. The host controller can obtain information to control the LED
from the R-IN32M3 Module via SPI protocol.
Details are shown in Table 5.3 and Table 5.4. Figure 13 shows an example of EtherNet/IP
LED connections.
Note: The R-IN32M3 Module does not support the address conflict detection, which
is optional in EtherNet/IP specifications.

Requirements
If power is not being supplied to the device, the module
state indicator is to be steadily off.
If the device is operating correctly, the module status
indicator shall be steady green.
If the device has not been configured, the module state
indicator is to be flashing green.
If the device has detected a major recoverable fault, the
module state indicator is to be flashing red.
Note: An incorrect or inconsistent configuration would be
considered a major recoverable fault.
If the device has detected a major non-recoverable fault,
the module state indicator is to be steadily red.
While the device is performing its power up testing, the
module status indicators shall apply the test sequence
described below.
-The module state indicator shall turn green for
approximately 0.25 seconds, turn red for approximately
0.25 seconds, and then turn green and retain that state
until the power-up test has been completed.
-If both module state and network state indicators are
present, the module state indicator test sequence shall
occur before or simultaneously with the network state
indicator test sequence(s). If more than one network state
indicator is present, then each network state indicator test
sequence may proceed in succession or simultaneously.
-After completion of this power-up test, the indicator(s) are
to represent a normal operational state.
