3.5 AC500-eCo/S500-eCo: Short description hardware
AC500-eCo processor modules contains the CPU with the core microprocessor of the PLC. It is
integrated with power supply, onboard I/Os and communication interface.
Functions:
● To download user programs
● To run the CPU
● To execute user programs in loops
● To monitor program input and output devices.
Processor modules are available in different performance classes and provide different numbers
of onboard I/Os.
Only one processor module is required for a valid system architecture.
AC500-eCo processor modules can be extended with option boards. Option boards provide
specific functionality. According to the processor module type, up to three option board slots
are available for extension. Each option board slot supports most existing types of option board
module. The option board modules provide the following functionality for processor module
extension:
● Serial interface RS232 (isolated) or RS485 (isolated or not isolated)
● Digital I/O channels extension (digital inputs, digital outputs, or mixed type)
● Analog I/O channels extension (analog inputs, analog outputs) for standard signal voltage or
current, but also temperature measurement with RTD/NTC or thermocouple sensors
● RTC real-time clock board for processor module PM5012 (other processor modules include
RTC functionality)
● Configuration address switch board for KNX protocol, for specific processor module
