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.
FAQ
What type of equipment is this PLC suitable for?
It is suitable for small to medium automation systems with distributed I/O, especially projects that need PROFIBUS DP communication.
How is it different from CPU 314C-2 PTP?
