CPU 1517-3 PN/DP: what it delivers
Built-in PID controllers are included for temperature and valve applications, removing the need for separate loop control hardware.
Connectivity and expansion
PROFINET I/O is standard; IRT is not included, so MRPD functionality is not available on this CPU. MRP is supported for media redundancy (Manager, Automanager, Client). MODBUS TCP, DHCP, DNS, DCP, LLDP, SNMP, HTTP/HTTPS, and UDP are all available. An RS-485 interface on X3 is included for point-to-point or multi-drop serial connections. Up to 8 communication modules (CMs/CPs) can be added for PROFIBUS, additional PROFINET, or Ethernet. This allows flexible fieldbus integration.
Forcing is supported, and the unit provides ERROR and MAINT LEDs for quick diagnostic status.
