The GE VMIVME-2540 is an Intelligent Counter/Controller (ICC) VMEbus slave module designed for high-precision digital measurement and control in industrial automation systems. It is widely used in applications requiring accurate event counting, frequency measurement, pulse-width measurement, and waveform generation such as robotics, automotive testing, telescopes, medical instruments, and machine tools. The module is ideal for systems needing robust, real-time signal processing with a simple memory-mapped user interface compatible with VMEbus architectures.
The VMIVME-2540 supports up to 24 channels of digital measurement and control via six System Timing Controllers (STCs), each providing four high-speed counter/waveform synthesis interfaces. These STCs can be configured individually or in groups for versatile measurement modes. The module features a 15 MHz 68HC000 CPU controlling data processing and queueing command execution with local zero-wait-state static RAM and EPROM firmware for reliability. It supports ANSI/IEEE standard 754-1985 for 32-bit floating-point arithmetic and operates with a high degree of precision and flexibility on a 64 Kbyte VMEbus memory window interface configurable for various address and data modes.
Key measurement capabilities of the VMIVME-2540 include event counting up to 4 giga events, frequency measurement from 1.16 mHz to 2.5 MHz, period/pulse width measurement with resolutions down to 400 ns, and quadrature position measurement supporting sin/cos inputs up to 1 MHz. It also supports pulse train and square wave generation from 0.0076 Hz to 2.5 MHz along with timer/periodic interrupt generation at rates between 0.0076 Hz and 1,000 Hz. The module’s programmable output allows 24 discrete control signals, pulse train generation, and quadrature position control with fine step resolution, suitable for automation and precise machine control.
