Beckhoff Ethernet
CPU with WinCE kernel should be selected, the valid sample period may be 0.25ms, it is more effective than WinXp or Win7 kernel. Please ask for the project example Beckhoff_pdaPrj.rar if needed, UDP is used, the data source type is 25, see section 4.3, Single PLC can send 1423Bytes/2ms once, PLC acquisition process is shown as below. it is triggered at rising edge, Program cycle is set to 1ms. Another PDAServer can read Beckhoff PLC variable name or memory address directly, no any acquisition process is required in PLC, the acquisition rate is 10ms or more.
Exit 360 antivirus, 360 guards. The controller default IP network segment is: 169.254.xxx.xxx, subnet mask is 255.255.0.0, The computer should be set to the same mask, Otherwise, no PLC can be searched. Run \tcat_2110_2232.exe to setup Beckhoff program tool, it’s kernel is CoDeSys.
You need to reinstall if there is the serial number. Run InfoSys.exe to setup manual and help documentation.
Set PC to the same network segment as PLC. Enter TWinCAT System Manager
Select target PLC.
Search device on the ethernet.
Broadcast search network to find device supported by BECKHOFF.
Select target PLC in the searching results.
Input PC or PLC password, Do not input if no password.
Enter hardware configure.
Scan devices.
Save result as Test.tsm, It will be automatically loaded when system manager startups.
Setup Base Time.
Enter to the PLC programming environment.
Double click PLC Configuration to choose target system type.
Double click Task configuration to create an 2ms task.
Right click to create a new program my_pda.
Add program my_pda to NewTask.
Choose run-time system.
Login, download, reset, stop, run.
Declare global 200 real array for PDA.
Open program my_pda Develop and save the project as temp1.pro, Compile and generate temp1.tpy Load compiled temp1.tpy in TwinCAT System Manager
Activate configuration.
Switch to run mode.
Set PC as PLC Replace c:\TWinCAT\Driver\TCRtime.sys to avoid blue screen.
Ethernet protocol should be installed when WinXp work as PLC (Even if related files are copied to the corresponding position for the test version the Ethernet function can not run normally), The serial number is needed when you install. \TwinCAT TcpIp Server\Install\TcpIpServer.exe
Copy ethernet library TcpIp.lib to \TwinCAT\Plc\Lib, add new library TcpIp.lib.
Run after project is loaded.
Copy TcTCPIPSvrCe.I586.CAB into the Flash card \Hard Disk\System\ with card reader for WinCE.
insert the card into PLC after copied and turn on. Start remote desktop "CERHOST.exe" of WinCE.
Run TcTCPIPSrvCe.I586.CAB, Extract to \Hard Disk\System\
The installation of ARM system is similar to above.
PDA server configuration for acquisition 300REAL/2ms is as follows. [1000,300CH,2.000ms,,25,Note,169.254.213.216] No,
