A-B 1770-KFD
The A-B 1770-KFD module is an interface module provided by Rockwell Automation (Allen-Br
adley) for its small PLCS, such as the SLC 500, to connect DeviceNet networks to RS-232 serial port devices. It can realize the data exchange between the device on DeviceNet and the RS-232 serial port device, thus expanding the communication capability of PLC.
Main function
DeviceNet interface: Connects to the DeviceNet network for communication with other DeviceNet devices.
RS-232 interface: Provides a standard RS-232 serial port, which can be connected to a variety of RS-232 serial devices, such as touch screens, printers, bar code scanners, etc.
Data conversion: Data on DeviceNet is converted to RS-232 serial port data and vice versa.
Protocol conversion: can support a variety of communication protocols, such as ASCII, Modbus and so on.
