12/14 MN05003004Z-EN Communication with thetarget PLC57Communication with the target PLCX Connect the PC to the routing PLC.X Select the target PLC with which you want to communicate forthe project.X Determine the communication settings for the PC and the PLCconnected to the PC.X Enter the target ID (Target ID = Node ID!) of the target PLC, asin the example, and log on.You can run the following functions:• Program download• ONLINE modification• Program test (Debugging)• Create bootable project• Filing source code.Note for project creationAssign two Node-IDs to the target PLC:X One ID for basic communicationX One ID for routingIf you are using an XC100, enter the same number for both IDs.The routing ID and the baud rate of the target PLC (XC 100) to therouting function can be defined in the “Additional parameters”window in the PLC Configuration. Enter the baud rate and thenode ID in the "RS232 l CAN routing settings" field.The CAN baud rate depends on the operating system version:Table 13: Baud rates for CAN connectionThe ID for basis communication is defined in the “CanDevice” inthe “CAN setting” tab a figure 80.ID and baud rate are transferred with the project download.ExampleIn the following example which is based on Figure 81 theprocedure for access to a PLC program is explained.You have connected the PC to the PLC with node ID “2” and wantto access the target PLC with routing ID “3”.X Open the project of the target PLC whose program you wish toedit or test.X First configure the parameters for the hardware connection PCn PLC (Node ID 2).X From the Online menu select Communication Parameters…X Click the New button under “local” channels.The “New Channel” window appears.X Select the channel in the “Device” window:Serial [RS232] [Level 2 Route] or TCP/IP [Level 2 Route].X You can assign a new name in the Name field, e.g."Rout_232".X Confirm with OK and return to the original window.Operating System VersionBaud rates < V. 2.0 f V 2.010000 j j20000 j j50000 j j100000 j j125000 j j250000 j j500000 – j800000 – j1000000 – jh To guarantee a fast data transfer, the routing should beperformed only with a CAN baud rate of at least125 KBit/s.Figure 80: CAN device parametersFigure 81: Diagnostics possibilitiesa XC100 with Node ID 1b XC200 with node ID 2, routing ID 127c PLC (e.g .
