In the bit-strobe mode, the master does not send data to the slave. However, when the
corresponding bit is set to “0”, the slave has to respond with I/O data to the master. When
the corresponding bit is set to “1”, the slave does not need to respond with I/O data to the
master.

Network Node Status Indication
z
Scan List Node Status Indication
The scan module conducts real-time monitoring on the nodes in the scan list and maps
the status of each slave to a bit. The user can acquire the status of the slave in the
network by monitoring the contents in D6032 ~ D6035. See the table below for the
devices in the ELC and their corresponding nodes in the network.

When the node in the scan list is in normal (abnormal) status, its corresponding bit will
be Off (On).
z
Scanner Module Status Indication
The user can acquire the status of the scanner module by monitoring D6036. When the
scanner module is working normally, D6036 = 0. When the scanner module is being
initialized, the high byte of D6036 = 1 and the low byte of D6036 = 0. When error occurs
in the scanner module, the high byte of D6036 = 2. See the low bytes of D6036 for error
codes.

Using Explicit Messages in the Application Program
Instructions in the ELC program can be used to trigger explicit messages from the
CODNETM module to another DeviceNet device.
