Explanation of the PN Function in the 106-D5xx Series Modules
- Diagram of SW1 Locations and Definitions for Reference
Lable | Description | On | Off |
TR | Terminate Resistance Set on at end one modul | Enable | Disable (Default) |
TD | Time-out Status Latch Status of the output signal when disconnect | Reset | Keep (Default) |
M0 | Keep it factory gefault setting. | Default | |
M1 | Keep it factory gefault setting. |
| Default |
PN | Digital Output/Input Logic | Normal (Default) | Reversal |
- The main function of the PN setting in the 106-D5xx series modules is?
- It is primarily used to modify the hardware logic for DIO
- With PN set to ON by default, the software control logic for DIO aligns with the hardware logic, as shown in Figure 1
- When changing PN to OFF, the software control logic for DIO becomes the opposite of the hardware logic, as illustrated in Figure 2
- Modules that support this function:106-D511-NNT、106-D502-XNT、106-D520-NXT
