Using Explicit Messages
The following example shows how to use explicit messages with a DeviceNet Communications Unit connected
to a CS1W-DRM21 DeviceNet Unit.
Example: Sending a “Operation Time Monitor Peak Value Read” Command
Example: DeviceNet Unit’s node address: 05
Unit number: 0
Unit address: FE hex (or 10 hex)
DeviceNet Communication Unit’s node address: 11
Operation
Reads the measured operation time (time required for input 2 to go ON after input 0 goes ON) of the Slice I/O
Unit with unit number 1.
The data is read using the EXPLICIT MESSAGE SEND command (2801).
The command data is written in words starting from D01000 in the PLC and the response data is stored in
words starting from D02000.
If the command does not end normally, the end code is stored in D00006 and the send command is re-exe-
cuted.
