APC3 Fieldbus Communication Controller（DP）
APC3 Fieldbus Communication Controller（DP）
APC3 is a fieldbus dedicated chip for the development of PROFIBUS DP intelligent slaves, supporting the complete DPV0 protocol. APC3 is fully compatible with SPC3LV and VPC3 working in DPV0/3.3V/1.5K dual-port RAM mode. It can be replaced directly without modifying the software/hardware design. Products developed with APC3 can pass the consistency and interoperability tests of DP products organized by PI. APC3 has faster message response time and lower power consumption.
