Terminal name for each pin
| Pin | Signal | Description |
|---|---|---|
| 1 | - | - |
| 2 | - | - |
| 3 | B Line | Positive RxD/TxD, RS485 level |
| 4 | RTS | Request to send |
| 5 | GND Bus | Ground (isolated) |
| 6 | +5 V Bus Output | +5 V termination power (isolated, short-circuit protected) |
| 7 | - | - |
| 8 | A line | Negative RxD/TxD, RS485 level |
| 9 | - | - |
| Housing | Cable Shield | Internally connected to the Anybus protective earth via cable shield filters according to the PROFIBUS standard. |
KEY POINTS
Prepare the cable for PROFIBUS-DP sold in the market as a communication cable.
Install terminating resistors at both ends of the network.
A terminating resistor is installed in the PROFIBUS-DP slave module. Turn the terminating resistor ON or OFF using the terminator switch on the front panel.
