Professional FAQ
- Q1: How can I check if my CPU 313C-2DP needs a memory card?
- A1: This model always requires an MMC for storing the program. If the CPU shows STOP after power loss, the MMC may be missing or corrupted.
- Q2: Can this CPU run motion tasks?
- A2: It supports basic positioning using pulse outputs. For complex motion, use external FM modules.
- Q3: What is a common field mistake during wiring?
- A3: Many installers forget the DI input delay settings. Using the wrong filter can cause missed fast pulses.
- Q4: How many devices can I place on the PROFIBUS line?
- A4: It can address up to 32 slaves as a DP master, but performance is best below 20 in high-speed networks.
- Q5: What is the best practice for grounding the system?
- A5: Use a single grounding point. Mixed grounding paths often introduce noise and unstable DI readings.
