Industrial Service Port


  • Hardware interface and control – Hardware Base – CPU offload
  • Integrated within the system, simply add new services, update any of the service    functions
  • Simple design of new industrial service port
  • Service Build in Blocks:
  1. All modes share same command formats and text file for configuration.
  2. interface setup – Automatic interface setup, writes / read / configures registers, flexible configuration setup – base on text file.
  3. Auto Task / s – Automatic interface setup, writes / read /    configures registers and status / alarms / interrupts, flexible configuration setup – Txt file (e.g. – for D2A service, writes values, read status automatically, on trigger / time base / CPU command)
  4. Managements task – Management write commands sequence (W/R)




General Description

Industrial Service Port (iSP) is the logic port implementation for each of the hardware interfaces. Implementation includes advance control and status / monitoring capabilities.

Industrial service ports used and integrated within Industrial End System (iES) units and can be integrated within Industrial Full Duplex Ethernet Switch (iFDX) units.

Industrial Service Port (iSP) design blocks responsible for the hardware interfaces (e.g. sensors, controllers, memory …), control and management.  advance hardware design technics which enable simple integrity and modularity, implement advance autonomic complex functions in hardware, simple to modify, interconnect to multiple ports (e.g. – multiple number of SPI Flash devices, UART’s …) simply add new / modify interfaces, user can set simple script for each of the interfaces for power up port initialization, automatic task’s and management tasks

Available service ports

  • I2C (support Eprom, Temperature sensors, A2D, D2A and generic I2C    interface support most of available sensors), high level I2C protocol configuration.
  • SPI Generic & SPI Flash (fully hardware implementation), high level SPI protocol configuration.
  • Magnetic card reader, Joystick interface …..
  • Multi-Port – Up to 256 active ports for single iSP Service
  • MDIO Controller
  • Generic Local Bus
  • Step Motor PID multi axis controller
  • PMbus
  • Encoder interface and distributor over machine communication
  • High speed, low jitter GPIO distributions
  • RS232 / RS485 master / slave
  • PLC Bus interface
  • Image sensors –snap sample, video sample, motion detect and more available options
  • FAN & FAN Try controllers includes temperature control
  • Image sensors interface & transport over communication network
  • Data Buffer over communication network, e.g. printing industry – print heads data controller, interface and distributer
  • System interrupt & event reporting
  • Hardware base status reporting – no need to run polling


Service flow example: D2A – Up to 16 D2A channels integrated with in one D2A iSP

  • Power Up
  • Automatic check service is enabled, if yes then move to step 3
  • Run Initialization:
    • Configure all D2A registers and parameters (can be tens of W/R command, up to 64 sequence operations per individual D2A channel)
    • Set default D2A output.
  • System Stand By
    • Run WD timer for auto task – Go to step 5
    • Management Command Request? 
  • User trigger / Execute auto task / management task Execute CPU / Auto task sequence (up to 64 sequential operations per D2A channel)
  • Update recorded data / Status / Management reply data
  • Go Back to System Stand By

User can build analog wave signal in automatic task, includes setup the tick time for each part of the wave build, can be different for each of the D2A channels.
