Protocol ‘COMx - Online access’¶
This protocol can only be used, if CM574 is configured as a PLC. If configured as Communication Module within a PLC project, this protocol is not available.
See protocol description for the serial interfaces COM1 and COM2 Setting_COMx_Online_Access: Setting COMx - Online Access Setting COMx - Online Access.
If the baud rate of the interface is changed to another value, a corresponding gateway channel must be created. Example: COM1 is to be operated with 115200 baud and the protocol ‘Online access’.
Configuration of COM1 -> Setting the baud rate to 115200 baud.
Selection of the gateway channel -> e.g. COM4_19200 with baud rate 19200 baud.
Login and download of user defined project (if required, create boot project).
Logout -> Interface is changed to 115200 baud.
Selection of the gateway channel -> e.g. COM4_115kB with baud rate 115200 baud.
Login -> with 115200 baud.
