    No responses from modules

    Hi all

    I purchased some PLCBUS modules including an appliance module and a lamp module. Both modules never seem to send a response back although they respond to on/off and dim commands.
    Both modules are located on the same floor and in the same outlet as the PC interface.

    27-6-2009 17:01:52 - PLCBUS Error - Too long wait for interface response to command: (255) A2 On Data1:0 Data2:0 Tx:False AckReq:True Ack:False IDreq:False Id:False 3PhReq:False RiscOK:False PlcBusOK:False

    27-6-2009 16:56:09 - PLCBUS Error - Too long wait for interface response to command: (255) A1 On Data1:0 Data2:0 Tx:False AckReq:True Ack:False IDreq:False Id:False 3PhReq:False RiscOK:False PlcBusOK:False

    What could cause this?

    #2
    Found it.
    One module was faulty and disrupted communication with all other modules.
