Conforms to DeviceNet
Master-Slave connection (polling, bit-strobe, COS, cyclic)
Conforms to DeviceNet communications standards.
Allocate any I/O data using the Configurator.
Allocate any data, such as DeviceNet-specific parameters and variable area for Digital
Indicators.
Input area: 2 blocks, 60 words max.
Output area: 1 block, 29 words max.
(The first word in the area is always allocated for the Output Execution Enabled Flags.)
Explicit message communications
CompoWay/F communications commands can be executed (using explicit message
communications)
Combination of multi-drop and T-branch connections (for trunk and drop lines)
