Siemens SIMATIC NET PROFIBUS manual Modes and Settings

6ZB5530–3AC30–0BA1 Infrared Link Modul (ILM)

6 Modes and Settings

To operate the PROFIBUS ILM, the terminating resistor, the data rate and the monitoring options must be set manually.

Note:

When shipped, the configuration is as follows:

âThe terminating resistor is inactive

âThe data rate is set to 1.5 Mbps

âThe “monitor link with acknowledgment pulse” monitoring mechanism is inactive.

âThe activation of the signaling contact is disabled.

The settings can be made after removing the cover from the basic module using switches S201 (transmission rate and monitoring mechanisms) and S202 (terminating resistor).
