The 1785-KE module from Allen-Bradley is a communication interface module used within the PLC-5 series of programmable logic controllers (PLCs). Here are some key points about this module:
- Function: The 1785-KE module provides an interface between a PLC-5 processor and an RS-232-C (EIA/TIA-232-E) communication port. This allows for serial communication between the PLC and other devices such as computers, printers, or other PLCs.
- Data Communication: It supports asynchronous communication and can be configured for different baud rates, data bits, stop bits, and parity settings, making it flexible for various communication requirements.
- Applications: This module is typically used in industrial automation environments where data exchange between the PLC and other systems is required. Common applications include data collection, monitoring, and control of manufacturing processes.
- Installation: The 1785-KE module is designed to be installed in the chassis of the PLC-5 system. It fits into one of the I/O slots and connects to the processor via the backplane.
- Configuration: The module is configured using software tools provided by Allen-Bradley, such as RSLogix 5. Configuration parameters include communication settings, protocol selection, and message routing options.
- Protocols Supported: The module supports various communication protocols including DF1 Full-Duplex, DF1 Half-Duplex, and ASCII. This versatility allows it to communicate with a wide range of devices and systems.
Overall, the 1785-KE module is a crucial component for integrating PLC-5 systems with other equipment and networks, facilitating efficient and reliable communication in industrial automation setups.
