Emerson E2 MultiFlex Boards, MultiFlex 16 Input Board, Gateway Model, Model Name Description

The Gateway board is an RS485 to RS485 converter. One side of the Gateway is always connected to the Retail Solutions I/O Network. The other side of the Gateway is the receiver bus (RS485). The receiver bus is connected to one or more RS485 devices depending on which type of Gateway is being used. The Gateway interfaces devices to the Einstein/E2 and legacy Retail Solutions controller (REFLECS) by simulating 16AI and 8RO boards using Retail Solutions standard I/O board protocol. The Gate- way can also convert third-party controller protocols to Retail Solutions protocol for custom cells created in the Einstein/E2 to interface with third-party controllers (Dan- foss, Woodley, etc.).

The Gateway performs one of two basic functions:

1.It allows control of and/or status of a device using I/O board simulation

2.Converts a third-party protocol to Retail Solu- tions I/O Net protocol and interfaces to a custom cell in Einstein/E2

2.2.2MultiFlex Boards

The MultiFlex line of control system boards provides a wide variety of input, output, and smart control solutions, all of which are based on a single universal hardware plat- form. The board design uses flash-uploadable firmware and plug-in expansion boards to configure the base plat- form board and apply it for use as an input board, relay output board, analog output board, or a combination I/O board.

2.2.2.1MultiFlex 16 Input Board

Figure 2-7- MultiFlex 16 Input Board

The MultiFlex 16 input board offers sixteen combina- tion analog/digital input points for use by Retail Solutions E2, Einstein, and REFLECS control systems. The Multi- Flex 16 may be used in retrofits with no additional hard- ware or software setup or upgrades.

The MultiFlex 16 is designed to be 100% compatible with the previous generation of Retail Solutions input

boards (the 16AI), communicates with the site controller via an RS485 connection to a REFLECS COM A&D Net- work or an E2 I/O Network. Dip switches on the board set the network ID (board number) and baud rate.

The board also provides both +5VDC and +12VDC output voltage points for use in powering transducers or other input devices that require power.

The MultiFlex 16 has a Hand-held Terminal interface Section 2.2.4, Hand-held Terminal (P/N 814-3110)that may be used by technicians to view the input voltage and engineering unit values for each input point without need of a voltmeter or front panel controller display.

Table 2-6shows the part number of the MultiFlex 16.
