Schneider-Electric recently posted a very nice video about the migration from SY/MAX to Unity Pro Quantum showcasing the SERI-T at Hunter Water.

Overview

The Niobrara R&D SERI module is a SY/MAX Ethernet Remote Interface. It replaces the CPU or RI interface in a SY/MAX® local or remote rack and maps its I/O to Modbus/TCP. The SERI can then be controlled via Ethernet from another PLC or SCADA.

Upgrading from SY/MAX to Unity or Concept is now as simple as adding entries to the Quantum's (or Premium or M340 or Compact or Momentum) Ethernet I/O Scanner for each SERI controlled rack. The SERI's powerful internal register mapper may be configured using a standard web browser or included PC software. This mapper allows the SY/MAX input and output modules to be logically grouped together to minimize the number of Modbus/TCP messages required for control. Most systems will only need a single combination read+write I/O Scanner entry per SERI. The SY/MAX status of each module register is available to Modbus/TCP for monitoring blown fuses, analog over-range, etc. Each output register has its own default value that the SERI provides when there is a loss of remote control.

Several features of the SERI address security concerns. The potential Ethernet master of the SERI is limited to a list of allowed IP addresses. A keyswitch on the front panel allows the rack to be halted or memory protected to prevent unwanted modifications to the configuration through the Ethernet network. The SERI may be placed in "Disable Outputs" mode for testing without actually controlling the I/O. The configuration is stored in FLASH memory for long term power outages and storage of replacement units.

The 10BaseT Ethernet port provides a standard Cat5 connection to the LAN. A standard SY/MAX pinout RS-422 serial port that supports both SY/MAX and Modbus/RTU protocols allows easy configuration of the IP address and troubleshooting with the included PC software. LEDs are provided to indicate module Power, Run, Program, Memory Error, I/O rack Error, Outputs Disabled, Mapper Configuration Error, Ethernet Error, Serial port RX and TX, Ethernet Link, Collision, RX, and TX.

The SERI does not, however, support Remote I/O from the local rack. Installations with Remote I/O drops require an SERI installed in each Remote I/O rack.

Specifications

Warranty/Manual: The SERI is furnished with a user manual on cd and carries a one year warranty from the date of shipment. During the warranty period, free firmware upgrades are available. See Niobrara's Standard Terms and Conditions of Sale for additional warranty information.

Dimensions: Standard SY/MAX register module. 1.5" wide by 13" tall by 6.5" deep. Approximately four pounds net. Rugged welded steel enclosure with baked on finish.

Power Requirements: From SY/MAX bus. 5 volts, 0.8 A.

Keyswitch: Three position keyswitch (Run, Run/Program, and Halt) on front panel allows lockout of changes once configured.

Ethernet Port: 10BaseT twisted pair Ethernet. Link and Collision indicators on module front panel. Modbus/TCP and HTTP protocols.

Serial Port: SY/MAX compatible RS-422 with same pinout as SY/MAX processor. DB9 female connector with slide lock posts. 9600 baud, even parity, SY/MAX or Modbus/RTU. Diagnostics, configuration, and firmware updates only.
