{"product_id":"prosoft-mvi69-dfcm-compactlogix-df1-communication-module","title":"ProSoft MVI69-DFCM CompactLogix DF1 Communication Module","description":"\u003cp\u003eThe MVI69-DFCM is a DF1 Half\/Full-Duplex Master\/Slave Communication Module built by ProSoft Technology as a single-slot, 1769-backplane in-chassis unit for Rockwell Automation CompactLogix and MicroLogix 1500 LRP processors. It provides two application serial ports (P1, P2) that are jumper-selectable for RS-232, RS-422, or RS-485 and independently configurable as a DF1 Master or Slave, plus a dedicated RS-232 CFG port for configuration, all terminated in RJ45. Each DF1 port supports full and half-duplex operation with CRC and BCC error checking and full hardware handshaking for radio, modem, and multi-drop links, exchanging up to 4,000 words of user-definable register data with the host processor over 125-word read\/write commands, including floating-point data movement. The module draws 800 mA max @ 5 VDC from the backplane (power-supply distance rating of 2), carries 500 V of optical isolation between the application ports and the backplane, and is rated for 0°C–60°C (32°F–140°F) operation. It is typically used to bridge a CompactLogix or MicroLogix processor to legacy DF1 devices – Rockwell PanelView terminals, other Allen-Bradley PLCs, and DF1-capable power monitors – with each Master port supporting up to 100 individually configurable read\/write commands.\u003c\/p\u003e\u003cp\u003eIn ProSoft's naming scheme, the MVI prefix identifies the Multi Vendor Interface in-chassis module family, the 69 designates the CompactLogix (1769) backplane platform as distinct from 56 for the ControlLogix\/1756 chassis, and the DFCM suffix marks the DF1 Communication Module protocol variant covered here. ProSoft now carries the MVI69-DFCM under its Legacy Products \/ Rockwell Automation In-Chassis listing rather than its current catalog, and specifies it as supported for CompactLogix and MicroLogix 1500 LRP controllers other than the 1769-L23E-QBFC1B, 1769-L16x, and 1769-L18x processors.\u003c\/p\u003e\u003cp\u003eThis unit ships as listed, in the condition shown.
