Explicit Message Communications
Section 2-6
4.
Set the response monitoring time to 6,000 ms minimum using the
CMND(490) instruction to send an explicit message.
Using C200HW-DRM21 or CVM1-DRM21
Set the response monitoring time to 6,000 ms using the IOWR(223) instruc-
tion to send an explicit message. (The message monitoring timer does not
need to be set with the DeviceNet Configurator.)

READ Command
The READ command is used to read data from the Fiber Amplifier Sensor
Communication Unit or the Sensors connected to it. When an OMRON mas-
ter is used, the formats of the command and response blocks are as follows:
Command Block
Response Block
Normal Format
Note The bytes of read data for Batch Read Incident Light Levels and Batch Read
Threshold Settings is twice the number of Sensors being read. The number of
received bytes is two plus twice the number of Sensors being read.
