Observe the following values for the number of connectable controllers per interface:
- A maximum of 8 slave controllers per RS 485 line
- Maximum of one RS 485 line length = 200 m
Figure 4.5 - Maximal RS 485 line length
It is important to differentiate between the RS 485 IN and OUT plugs. Connect the incoming cable (from the master
controller or the previous slave controller) to the RS 485 IN plug and the outgoing cable (going to the next slave
controller) with the RS 485 OUT plug. This is particularly important if the power supply is to be forwarded to the fol-
lowing slave controllers (please refer to the next section).
