WL Circuit Breaker COM15 and COM16
Commissioning Procedure
1. Verify that the COM15/16 module is mounted properly at the top of the breaker so that
the microswitches on the bottom of the module are activated when the breaker is drawn
in and out of the guide frame (only applies to draw-out breakers).
2. Verify that the four black cables coming out of the COM15/16 module are landed on
X8:1, X8:2, X8:3, and X8:4 (wires are labeled accordingly).
3. DP Write is enabled on the COM15/16 module (put jumper across terminals 1 and 2
on the module).
4. Put terminating resistor in the COM15/16 module or the last CubicleBus module.
5. Change the COM15/16 address to a unique identifying address (1-125), factory
default address is 126.
6. Briefly interrupt the 24VDC supply to the COM15/16 module in order to activate the
new address.
7. Verify that the COMM. LED is green on the WL ETU trip unit.
8. Verify that the CubicleBus LED is steady green on the COM15/16 module.
9. Verify that the Profibus or Modbus LED is green on the COM15/16 module.
10. The preferable way to set up the COM15 Profibus DP slave device is with Switch ES
Power Object Manager in STEP7. The slave can also be set up with integration of the
GSD file in the Profibus-DP Master hardware configuration tool.
11. Enable Sync and Freeze in Profibus DP master (if applicable)
12. Cyclic data exchange should be minimized for the specific application in order to
maintain acceptable speeds.
13. For initial communications verification use default assignment Basic Data Type 1.
This will initiate basic cyclic data exchange with the COM15/16 module. After
communications are established, basic data type can be changed and modified. DPV1
acyclic data exchanges should be set up last after communications are active.
14. If communications can not be established, request complete diagnostic data from the
COM15/16.
