Siemens SIMATIC NET PROFIBUS manual Infrared Link Modul ILM 6ZB530-3AC30-0BA1

Infrared Link Modul (ILM) 6ZB530–3AC30–0BA1

+Make sure that the infrared link cannot be disturbed, for example by “interrupting” the link with obstacles, extraneous light etc.

When cascading with PROFIBUS ILM, only one segment with master nodes is permitted, the cascaded segments must only contain slave nodes.

+Make sure that the two infrared transmission links do not interfere with each other, in other words either the spatial arrangement of the modules (clearance) or a physical barrier (wall) must ensure that each PROFIBUS ILM can only detect the transmission of its partner module and cannot detect emissions from either of the modules of the other infrared link.

Note

When cascading, the delay times of the PROFIBUS ILMs must be taken into account. The delay times are shown in Table 3 and must be included in the calculations during configuration.
