Sending Explicit Messages

Restrictions

Serious injury may possibly occur due to loss of required safety functions. Do not
use explicit message data as safety data.
The necessary measures for safety communications are not taken for explicit
message communications.
Note
• One address can be set in the user program for the trigger address.
• The NE1A-series Controller's internal I/O memory is sent as a response
to an explicit message. Explicit messages can be sent from a user pro-
gram in the Controller, but internal information in the Controller cannot be
used as send message data.
• Response data to explicit messages cannot be used in an NE1A-series
Controller's user programs.
• Sending an explicit message command is possibly to the nodes on the
same DeviceNet network.
!WARNING
Refer to DeviceNet specifications for details on explicit message parameters.
