It occurs when for any reason there is an interruption in the communication between the CFW 11 and the network master In this case the alarm A129 or the fault F229 depending on the P0313 programming will be signalized through the HMI In case of alarms the alarm indication will automatically disappear at the moment the condition that caused the error no longer exists It occurs only when the inverter is on ine Correction Verify cables and connectors A bad contact in these elements may cause intermittent alarms Make sure the PLC is in execution mode RUN A130 F230 Anybus CC Module Access Error Description It indicates Anybus CC comunication module access error Actuation It occurs when the control board is not able to read information from the module or when there is hardware incompatibility In this case the alarm A130 or the fault F233 depending on the P0313 programming will be signalized through the HMI It is necessary to cycle power of the inverter so that a new attempt to access the Anybus CC module be made Correction Verity if the Anybus CC module is fitted in correctly on the XC44 connector Make sure there are not two options WEG board and passive Anybus CC module installed simultaneously having the same interface RS232 or RS485 In such case the WEG optional board will have preference over the Anybus CC module that will remain disabled and indicating A130 43

Anybus CC Speed Ref Intranet local Figure 2 4 Window with the drive parameters Important The parameter writing via WEB acyclic is performed in a way similar to the I O data cyclic Thus if a variable is accessible via cyclic as well as acyclic connections one will be overwritten by the other In the case above writing in the Anybus CC control word will be almost immediately overwritten by the value sent via the cyclic connection The same happens with the Anybus CC speed Ref word In this case one gets the wrong impression that the command had not been executed 15 3 Accessory Kits Passive Modules In order to make available a RS232 or a RS485 422 interface for the CFW 11 one of the communication kits described next can be used The operation of those modules follows the same principle of the serial interface For this reason it is not possible to use them simultaneously with the RS485 01 RS232 01 and CAN RS485 01 communication kits If this occurs the A130 alarm message will be showed on the HMI to indicate hardware incompatibility These passive devices work only as physical layer converters not performing any processing over the data flow This means that any serial protocol programmed in P0312 Modbus RTU TP can be used with these interfaces Refer to the CFW 11 Serial Communication Manual for more information on the operation of those modules Installation inst

Protibus distinguishes its devices between masters and slaves Figure above Masters determine the data communication in the bus A master can send messages without any external request every time it has access right to the bus token they are also called active stations Slaves are remote devices like I O modules transducers valves drives etc they do not have access right to the bus and can only send messages to the master when requested they are also called passive stations Profibus DP is also a multi master system This means that several active stations can exist in the same bus controlling different slaves In this case a telegram called token is passed among the masters in order to guarantee a single access right to the bus Therefore the access to the Profibus bus includes the procedure of the token passing among the active stations and the master slave procedure for the communication of masters with the slaves 6 2 1 Protocol Architecture Profibus is based on international standards being its protocol architecture oriented to the OSI Open Systems Interconnection layer model from ISO In this model the layer 1 physical layer defines the physical characteristics 35 of the transmission The layer 2 data link layer defines the access protocol to the medium And the layer 7 application layer defines the application functions Fields of Application Manufacturing Process Building User DP Functions
