PROFIBUS DP slave with SPC3 ASIC
The 6ES7183-0AA01-0XA0: This SIMATIC DP IM 183-1 is a slave module for PROFIBUS-DP networks, designated as a spare part by Siemens. It uses the SPC3 ASIC and supports a transmission rate up to 12 Mbit/s, making it suitable for high-speed slave applications in distributed automation systems.
Processor and memory stack
The module is built around an 80C32 microcontroller running at 20 MHz, paired with 32 KB SRAM and 64 KB EPROM. Firmware scope ranges from 4 to 24 KB inclusive of test programs. This provides deterministic response for slave nodes under PROFIBUS DP cycle times.
Supply and power budget
Operates from a 5 V DC supply rail, drawing typically 250 mA. This consumption fits within the backplane capacity of most SIMATIC DP master stations; plan the 5 V budget on the rack accordingly.
