The Allen-Bradley 2707-M485P3 is a DTAM Micro operator interface with an RS-485 communication port. It gives an operator a local display and keypad for monitoring and manipulating process data used by PLC-5 and SLC 500 family controllers.
Its front-panel architecture combines a two-line, 20-character LCD, eight function keys, a numeric keypad, status indication, a power connector and the communications port. Application screens and controller data are held in the terminal configuration rather than in a separate I/O module.
The RS-485 version supports DH-485 network use and point-to-point communication. In the stated controller arrangements, the signal path runs through the terminal communications port to the PLC-5 Channel 0, SLC DH485 port, or a MicroLogix 1000 through an AIC+ interface.
The selected 2707-M485P3 differs from DTAM Micro RS-232 versions by its RS-485 port. It also differs from DTAM Plus terminals, which use a different terminal platform and option set.
