The G4LC32SX is a cost effective, high performance controller designed to work within the Opto 22 family of rugged, compact controllers and I/O units.
IMPORTANT NOTE: Due to difficulty obtaining parts, this controller is obsolete and no longer available.
For new development, system expansion, or modernization, we recommend using the SNAP-PAC-S2 standalone controller and the PAC Project Professional software suite. SNAP PAC S-series controllers with PAC Project Pro offer a migration path for legacy mistic systems.
For migration information, see the FactoryFloor to PAC Project Migration Technical Note.
This README file lists revision changes made to the firmware used in the following Opto 22 controllers that run OptoControl strategies: G4LC32, G4LC32SX, M4, M4IO, M4RTU, SNAP-LCSX, SNAP-LCSX-PLUS, and SNAP-LCM4.

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.
This download contains the current firmware for the G4LC32SX controller. The download also includes firmware for SNAP-LCM4, SNAP-LCSX, SNAP-LCSX-PLUS, M4, M4RTU, and other Opto 22 OptoControl-based controllers.
Note: This firmware is used in conjunction with OptoControl 4.0 and FactoryFloor 4.0 or higher. Please see important information about this firmware version in the README file included in the download.
Current release of 16-bit Cyrano firmware. This firmware is required to run Cyrano strategies on Opto 22 controllers. This file installs the Opto 22 Flash 200 utility (version R3.1i) and Cyrano firmware (version R3.2j).
The predecessor to OptoControl, Cyrano is a DOS application for flowchart control programming. This software does not run under Windows NT.
Mistic MDS is the predecessor to OptoServer. It is a DDE-only server for the Cyrano tagname database that operates under Windows 3.x.
Mistic MMI is the predecessor to OptoDisplay. It is a 16-bit Windows 3.x Man-Machine Interface package that is tightly integrated with Cyrano.
Use this library file together with the Modbus Integration Kit for OptoControl.
