Abstract :
The author compares the protocols of two major manufacturers, Allen Bradley and Gould, with respect to their capabilities for data exchange and explores the minimum functionality that a protocol emulator should provide. He also discusses what protocol emulation cannot achieve. The OPTO-22 Optomux protocol is also briefly covered. It is concluded that protocol emulation can be used as a simple, low-cost solution to data exchange between controllers from various manufacturers. Most protocols provide a minimum functionality that can be cross-emulated. This minimum functionality is sufficient for most supervisory control and data acquisition applications
