Comparison and Replacement
-
Compared with CPU 314C-2 PTP: the DP version adds PROFIBUS DP for network communication, while the PTP version is oriented toward RS485 serial communication.
-
Compared with CPU 314C-2 PN/DP: PN/DP is more suitable for Ethernet-based and more advanced communication requirements.
-
Replacement suggestion: choose the DP version for PROFIBUS DP network integration, or choose PTP for basic control and serial communication.
