Explicit Message Communications Section 2-6
2-6-6 Using Explicit Messages: Example
The following example is for sending explicit messages using a CS1W-
DRM21 DeviceNet Unit.
Operation • The threshold of the Sensor for unit number 1 connected to the Fiber
Amplifier Sensor Communication Unit is written.
• The EXPLICIT MESSAGE SEND (2801) command is used to read data.
• The command data is written starting at D01000 in the CPU Unit, and the
response data is stored starting at D02000.
• When a command is not executed properly, the end code is stored in
D00006, and the command is resent.
