Dear Members: I have connected CX9020 with a high voltage power supply via canopen. I have loaded the PDO's from the eds file. I want to read and write the value of voltage in PLC Control. In my list of TPDO's and RPDO's I dont find information related to Voltage. How can I configure the required sdo and link it to the PDO and then to the variable.The index of my voltage value is 21F5, Bit size is 16 and the length is 4. Now from the Beckhoff files I found this information for variable mapping 1.First delete the PDO (set 0x1400ff, or 0x1800ff, sub-index 1, bit 31 to "1") 2.Set sub-index 0 in the mapping parameters (0x1600ff or 0x1A00ff) to "0" 3.Change mapping entries (0x1600ff or 0x1A00ff, SI 1..8) 4.Set sub-index 0 in the mapping parameters to the valid value. The device then checks the entries for consistency. 5.Create PDO by entering the identifier (0x1400ff or 0x1800ff, sub-index 1). But I am unable to implement it. Can someone explain these steps to me? Thanks in advance

Dear Members: I am new in Beckhoff Twincat system. I am working on a project. I am using CX9020 as my embedded PC. I have connected EL5101 as incremental encoder interface with CX9020. I was able to find EL5101 in my system manager. The operation mode is Free Run/SM-Synchron and EL5101 is in OP mode. The power and the run LED is green. I have also configured the NC-configurations. I have Append Axis and then selected Encoder Axis in the types. In my Axis_Enc I have linked NC-Encoder with EL5101. Now the EL5101 ENC Status compact inputs and ENC Control compact outputs are now linked to variables in the Axis_Enc in the NC-Cofigurations. Now I don’t know what to do next. I have not connected Heidenhain incremental encoder ERN 460 with my EL5101. I have 3 different input terminals A A’,BB’,CC’ and also Latch 24V and Gate 24V in my EL5101. The incremental encoder also have 3 types of output wires AA’,BB’,CC’. Also the incremental signal of my ERN 460 is 5V TTL. I want to know do I need to connect all the output wires of encoder AA’ BB’ CC’ to their corresponding terminal in the EL5101? What about Latch 24V and Gate 24V? What I have to do with these terminals? Is there any sample program or any step by step guide that how can I measure rpm through this setup? What kind of variables and data type I have to define in my PLC Control and to which physical input and outputs I have to link them? Is there any high speed counter in Twincat PLC Control? Please reply. Thanks.

Dear Members: I am new to Twincat System. I am working on a project. I have connected CX9020 with my laptop through ethernet cable. I was able to find CX9020 through broadcast search and I was successful in connecting it. I also found my Inputs through scan devices. The TC LED light on my CX9020 was blue then and I was in config mode.But when I clicked Activate configuration my CX9020 was not connected with Twincat and there was a cross on CX9020. The LED light on CX9020 is green now. There is also written Timeout in the software. I am unable to find CX9020 in broadcast search. Now I cant get my system in the normal mode. Also the yellow Timeout is not going. Everytime I start my system and try to get connect with CX9020 Timeout appears. Please tell me How can I remove this Timeout status.
