- Communication modules  (up to 4)
- Integrated Ethernet or ARCNET (option)
- Fieldbus-neutral interface for slave function or programming
- COM1 / COM2 for programming, ASCII, Modbus or CS31 fieldbus
- Battery for retain data and real time clock (option)
- Power supply
- Expandable with up to 10 local I/O modules
 
Communication Onboard
- Ethernet for:
- TCP/IP
- Modbus TCP
- UDP/IP
- Programming
- COM1 (RS232 / RS485) for:
- Modbus
- ASCII
- CS31 bus
- Programming

Display and Front Elements
- LCD-Display for
- Diagnosis, error codes
- Bus address setting
- Square displays status of fieldbus or device written beneath. Acting as a LED
- Triangle indicates the selected device to be read or configured.
- LED’s for State of
- PWR: Power on
- RUN: program running
- ERR: Error detection
- Keypad to operate local
- RUN: to start and stop program
- VAL: for future functions
- ESC: to exit menu without saving
- OK: to exit menu with saving
- DIAG: for diagnosis of error codes
- CFG: to set address local for ARCNET, CS31 and FBP
 
Local Diagnosis with LCD-Display
- In case of an error the LCD display shows deep information of this error.
- Example: error class E3 = light error with error code 008 = empty / missing
- With help of the DIAG button up to four levels d1..d4 show deeper information about error
- d1 indicates the component which has sent the error (CPU, COM1, FBP, IO-Bus, etc.)
- d2 defines the faulty device within the component
- d3 defines the part of the module with an error (slot)
- d4 defines the channel within the module
 
The SD-Card
- The SD Memory Card is used by AC500 like a disk drive
- For Data transfer between a PC with SD-Card-Interface and AC500
- For Firmware update of
- AC500 CPU and/or Boot code update
- Display-Controller
- Couplers
- I/O modules on IO-Bus
- For Loading and saving of
- user program (boot project)
- Source code of user program
- Retentive variables
- User data
- Option, not necessary to run user program!
