Universal protocol converter and counter module for Profibus DP

aXpbc1 is an intelligent Profibus slave which, depending on the application area, makes available serial protocols in the Profibus DP network or autonomously executes fast counting functions.

Features of aXpbc1

  • Various manufacturer-specific protocols 
  • Standard protocols (R3964, RK512, ASCII) 
  • Several physical interfaces (RS232, RS422, RS485, TTY) 
  • Several counting functions 
  • Frequency and engine speed measurement 
  • Pulse dosing 
  • Profibus slave 
  • Configuration via mode switch

aXpbc1 is a Profibus slave which, depending on the firmware, serves as a protocol converter or counter module. The great plus is that the required firmware can be loaded via the Profibus interface in connection with the automationX system.

Used as a protocol converter, aXpbc1 connects fire alarm systems, video cross bars, barcode scanners, scales, traffic control systems, multi-function measuring devices, only to name a few, via Profibus DP with the higher-level control systems.

Used as a fast counter module, you can chose between several endless counting functions, one-time counting functions, periodic counting functions, frequency measurement, engine speed measurement, dosing functions, and period measurement.
