Availability: Obsolete
OBSOLETE SNAP Controller with Two COM Ports for FactoryFloor systems

Production Specification

*** The SNAP-LCSX is obsolete and no longer available as of January 2014, due to the unavailability of essential parts.***

For new development we recommend using the SNAP-PAC-S2 standalone controller and the PAC Project Professional software suite instead of the SNAP-LCSX and FactoryFloor. SNAP PAC S-series controllers with PAC Project Pro offer a migration path for legacy mistic systems. The SNAP-PAC-S2 controller is slightly larger than the LCSX. It provides more power and offers more features, including 4 configurable serial ports plus Ethernet network connections.

For more information on migration, see the FactoryFloor to PAC Project Migration Technical Note.

To compare product features, see Legacy and Current Product Comparison and Compatibility Charts.

The SNAP-LCSX controller provides real-time industrial control in a small footprint. It is designed to work with the FactoryFloor software suite and with SNAP brains, racks, and analog and digital SNAP I/O modules.

The SNAP-LCSX is NOT compatible with the PAC Project Software suite.

Opto 22 remote I/O using RS-485


COM 0: jumper selectable as RS-232 or RS-485, 2-wire or 4-wire. Modem control signals are present for RS-232 (RTS, CTS, DTR, DCD, and R). Pull-up, pull-down, and termination are jumper selectable for RS-485 operation, allowing multidrop operation.

COM 1: dedicated Opto 22 remote I/O port (2-wire RS-485 with interrupt capability)

COM 2 and COM 3 (LCSX-PLUS only): jumper selectable RS-232 or RS-485. RS-232 signals include TX, RX, RTS, and CTS. RS-485 is either 2-wire or 4-wire, with selectable termination and biasing.

Note: All ports use low-noise slew-rate-limited drivers and are transient protected to 400 W.

BETA firmware for OptoControl-based controllers

This download contains BETA firmware for Opto 22 controllers running OptoControl strategies.

Beta Version Disclaimer:

OptoControl is a legacy product, which is no longer getting new features and no longer going through official release cycles. Beta versions of the firmware are made available as-is for those who need the related bug fixes.

In general, beta versions will include bug fixes since the last official release, without adding new features. This usually enhances product stability without introducing unwanted side effects. Beta versions for legacy products have been through basic testing only, and will not be formally tested.

Ultimately, the choice will be up to the user as to whether the benefit of using the beta version is worth the risk. We simply want to make the beta version available so that you have options.

SNAP-LCSX Controller Firmware

This download contains the current firmware for the SNAP-LCSX controller. The download also includes firmware for SNAP-LCM4SNAP-LCSXSNAP-LCSX-PLUSM4M4RTU, and other Opto 22 OptoControl-based controllers.

AutoCAD Drawings

This file contains AutoCAD drawings of Opto 22 products dating from 1988 to 2003. These are the same drawings that have been available on our BBS. Included is an Excel file describing the file names and relevant Opto 22 part numbers.

Cyrano Flash Firmware

Current release of 16-bit Cyrano firmware. This firmware is required to run Cyrano strategies on legacy Opto 22 controllers.
