i want to write and read data across the CI853 Ports ( com1 & com2 )
the data stored in markers ( memory location )
how can I make this ?!?!?!!?
The first, you need to define is the protocol you will use,
this module you can use: Modbus RTU, Comli, Siemens 3964, or you can create your own serial protocol.
is there a manual "3BSE035982-510_en_AC_800M_5.1_Communication_Protocols" that explain all this matter in detail.
please review in the attachment.
Use 'MBConnect' to initiate a communication channel and establishes a connection with a slave device. Then use 'MBRead' to read variables and 'MBWrite' to write variables. For further details how to use the blocks refer the corresponding online help.
