BRIDGE CS-L2 | |
8 Status display and error messages
•The lamp test (all LEDs on) is not activated when switching on the network, but only with master-reset and soft-reset.
•If the memory card is pulled during operation, after one minute, the bridge functionality can no longer be guaranteed. This is signaled by a flashing STOP LED and the LED USR1.
•If the BRIDGE CS-L2 recognizes an error in the bus coupling TPM478, the bus coupling is automatically reinitialized and the LED USR1 flashes rapidly. If reinitialization is successful, the RUN LED is continuously illuminated, while a more persistent error is indicated by the STOP LED. Moving the key switch in any way (e.g. from RUN to RUN- P or vice versa) will cancel the flashing LED USR1.
•If the BRIDGE CS-L2 recognizes an error in the bus coupling CP5412 A1, the bus coupling is automatically reinitialized and the LED USR2 flashes rapidly. If reinitialization is successful, the RUN LED is continuously illuminated, while a more persistent error is indicated by the STOP LED. Moving the key switch in any way (e.g. from RUN to RUN- P or vice versa) cancels the flashing LED USR2.
9 Operational modes switch (key switch)
•The switch setting RUN-P is functionally identical to the setting RUN.
•In the STOP operational mode (key switch setting), the coupling via the BRIDGE CS-L2 is interrupted. The couplings for the PROFIBUS-TM and for the CS275 continue to participate in the token circulation and indicate this through the display on the front plate. In this mode, messages can get lost on the BRIDGE CS-L2.
•In the case of a soft reset, all messages in the buffer are deleted and the bus couplings TPM478 and CP5412-A1 or. IF964-DP are reset. Afterwards, communication is restarted by initializing the bus couplings TPM478 and CP5412-A1 or IF964-DP. In addition, a LED lamp test is carried out.
