Product Description:
The ECPP40-01 control module is produced by B & R Automation and belongs to the ECP Multi Control Modules series. It is used in distributed control systems to offload deterministic tasks from the primary CPU, allowing faster sequencing and coordinated motion across several axes in a machine rack. As a parallel processor card, it fits into the vendor’s modular backplanes and executes application code by using external EEPROM and SRAM resources. This arrangement helps distribute control workloads in machines that require repeatable timing across several synchronized functions.
Within the rack, the module operates as a Parallel Processor, so it works alongside the main PLC and handles time-critical routines independently. Program size is capped at 4.7 KB, which is the maximum compiled instruction block the module can execute per cycle. For online diagnostics, the board provides 1 x TTY port communication, and this bidirectional channel supports simple character-based monitoring without using the fieldbus. The computation core is identified as Type A, and mechanical installation is limited to MULTI/MIDI Racks. These limits keep the module aligned with the intended backplane formats and available processing resources.
Signal integrity between the module and the host rack is supported by an electrically isolated receiver stage, which helps decouple data lines and reduce ground-loop issues. Application code is stored on a socketed EEPROM of 16 KByte, while a matching SRAM area holds working variables during operation. Runtime libraries occupy the dedicated operating memory labeled EE32, leaving the limited program area available for user code. For setup or data logging, a separate 1 x RS232/TTY interface is provided, and this serial channel can operate alongside the online TTY port without resource conflicts.
