Connection Of Fbs-Plc With Host Computer Or Intelligent Peripherals - FATEK FBS Series Manual

Besides the above area network connection, FBs-PLC can also be connected using MODEM via the phone line (either
leased line or public phone line) to form remote multiple PLC Link. (When using a public phone line, the Master PLC
will perform consecutive dialing for all its Slave PLC.)
2.2.2 Connection FBs-PLC with Host Computer or Intelligent Peripherals
Any one of the five communication ports on FBs-PLC can be used to connect to an upper-level computer or other
systems, with this architecture, the FBs-PLC is playing the Slave role. FBs-PLC supports the FATEK and Modbus
protocol. Connection can be established as long as the upper-level computer or intelligent peripherals use either one of
the two protocols. In the application, in which driver for FATEK or Modbus is not available, FATEK also provide
standard DDE communication server, which enables FBs-PLC to connect with any computer system supporting DDE.
