2-5 DeviceNet Remote I/O Communications
2-5-1 Master Word Allocations
The E3X-DRT21 data is stored in the IN Area of the DeviceNet master. Select
one of the following three operating modes using the DIP switch.
The DeviceNet Configurator can be used to set the connection type. The
Fiber Amplifier Sensor Communication Unit supports bit-strobe, polling, COS,
and cyclic connections. Refer to Appendix C DeviceNet Connection Settings
for details.
Remote I/O
Communications
One-word Mode
(Pins 1 and 2 OFF)
Up to 13 Sensors can be connected in this mode. One word is allocated to
each Sensor in the IN Area of the master. Fiber Amplifier Units are automati-
cally assigned unit numbers in ascending order starting from the Communica-
tion Unit (left side).
■
Mobile Console Communications Flag
Bit 13 turns ON when the Mobile Console is connected to the Communication
Unit. When the Mobile Console is connected, the DeviceNet Configurator or
explicit message communications cannot be used to perform setting and
monitoring operations.
■
Sensor Communications Error Flag
Bit 14 turns ON when the registered number of Sensors does not match the
number of Sensors that are enabled to communicate, or when a communica-
tions error occurs after communications have been established with the Sen-
sors.
