CPU LED Status and Mode S/W
CPU Status Indicators
| Indicator Label | Description |
|---|---|
| PWR | Red LED is illuminated when power is on. |
| RUN | Green LED is illuminated when CPU is in RUN mode. |
| ERR | Red LED is illuminated to indicate an error. Off if no error is present. |

|---|---|
| RUN | Executes the user program. Online edits are possible. Can not perform a full Write from XG5000 in RUN mode. |
| STOP | Default behavior is to not RUN the user program. This is the default position of the CPU. XG5000 allows user to use this position as a Remote Run from their program. XG5000 can perform a Write operation from this mode. |
CPU Power and RS485 Terminating Switch
| No. | Name | Purpose |
|---|---|---|
| 1 | Power terminal | Power supply terminal (24VDC). Uses cable model number XGB-CON-3PX. |
| 2 | Expansion module lock | Slide to CLOSE when installing an expansion module. Slide away from CLOSE to remove a module. |
| 3 | Terminating resistance selector switch |
Terminating resistance selector switch for built-in RS-485.
Note: Not having both switches on the same setting may cause communication issues. |
CPU I/O Connector
-
XEM-Dx32Hx series CPUs require break-out terminal block model number XTB-40H.
-
Requires one of these Smart Link cables: C40HH-05SB-XBI, C40HH-10SB-XBI, C40HH-15SB-XBI, C40HH-20SB- XBI, or C40HH-30SB-XBI.
Note: The terminal block label that comes with XTB-40H does not match the PIN-out of the XEM CPU I/O Connector. AutomationDirect has provided a new label to print that will include the XEM CPU I/O Connector mapping with the XTB-40H pin out. You can download the label from the AutomationDirect website here.
