DeviceNet Remote I/O Communications
Method 3 can be performed by allocating real I/O data and Generic Status
Flags independently in the Master's connection path using the Configura-
tor. (This method can be used only with CS/CJ-series Master Units.)
Example of Allocation Using Method 2
The Generic Status Flags are as follows:
Bit
0 Basic Unit's I/O Power Status Bit
0: I/O power supply ON
1: I/O power supply OFF
1 Expansion Unit's I/O Power Status Bit
0: I/O power supply ON
1: I/O power supply OFF
2 Network Power Voltage Drops Bit
0: Normal (Higher than set monitor value)
1: Error (Same as or lower than set monitor value)
3 Unit Maintenance Bit
0: Within range (Lower than set monitor value)
1: Out of range (Same as or higher than set monitor value)
4 Sensor Disconnected Bit (Environment-resistive Input Terminals only)
0: Connected (all inputs connected)
1: Disconnected (one or more input is not connected)
5 Short-circuited Bit (Environment-resistive Terminals only)
0: Normal I/O (all I/O points normal)
1: Short-circuited I/O (one or more I/O point is short-circuited)
6 Operation Time Over Bit
0: Within range (all output-to-input sets are
lower than set monitor value)
1: Out of range (one or more output-to-
input set is same as or higher than set
monitor value)
7 Connected Component Maintenance Bit
0: Within range (all I/O points are lower than set monitor value)
1: Out of range (one or more I/O point is same as or higher than set monitor
value)
