ABB 07MK92 GATS110098R0161 DIN-Rail Communication Module

Application Scenarios

A pharmaceutical manufacturing plant was struggling to integrate a new generation of analytical instruments with its existing ABB AC31 control system. The instruments communicated via a proprietary RS-485 protocol that was incompatible with the standard AC31 I/O. Instead of replacing the entire control infrastructure, the plant deployed the ABB 07MK92 as a protocol translator. The module was programmed to interpret the instrument’s data format and exchange it with the AC31 basic unit using predefined function blocks. This solution enabled real-time quality monitoring without costly system upgrades, demonstrating how the ABB GATS110098R0161 extends the life and capability of legacy automation platforms.

In another case, a water treatment facility needed to consolidate data from multiple remote pumping stations into a central SCADA system. Each station used different serial communication standards. The ABB 07MK92 was deployed at each site, with its configurable COM3 and COM4 interfaces set to RS-485 for field device communication and COM5/COM6 set to RS-232 for modem links to the central control room. The module’s 128 kB Flash EPROM stored custom C programs that handled data acquisition, error checking, and scheduled reporting. This approach eliminated the need for expensive communication gateways and simplified the overall system architecture.

Technical Principles and Innovative Values

The ABB 07MK92 derives its power from a unique architecture that separates communication processing from the main AC31 controller’s logic execution. It acts as an intelligent peripheral, equipped with its own microprocessor and memory, capable of handling complex serial communication tasks independently of the basic unit’s scan cycle.

Innovation Point 1: Freely Programmable Protocol Handling. Unlike fixed-protocol communication modules, the ABB GATS110098R0161 allows users to define their own communication protocols using the “C” programming language. This is enabled by an extensive function library and the 907 MK 92 development environment on a PC, which connects to the module via the COM3 interface. This flexibility means the module can interface with virtually any serial device, from legacy barcode readers to custom-built sensors, making it a highly adaptable solution for system integration projects.

Innovation Point 2: Configurable Interface Standards and Isolation. The module features four serial interfaces, with COM3 and COM4 offering selectable RS-232, RS-422, or RS-485 standards. Importantly, COM3 and COM4 are electrically isolated from each other and from the rest of the unit. This galvanic isolation is critical in industrial environments to prevent ground loops and protect the controller from voltage spikes, a feature that distinguishes the ABB 07MK92 from simpler, non-isolated serial adapters.

Innovation Point 3: Seamless Integration with AC31 System. The module connects to the AC31 basic unit via a specialized parallel networking interface, using a 40-pin flat ribbon cable. Data exchange is managed through standard function blocks (SISEND, SIREC) within the AC31’s programming environment. This integration allows the ABB 07MK92 to appear as a natural extension of the controller, simplifying application development and system diagnostics.
