1) The interfaces, etc. available on the device or module have been numbered as such for the purpose of clear differentiation. This numbering may deviate
from the numbering used by the respective operating system, however.
2) This interface can only be used in Automation Runtime and is referred to as IF7 in Automation Studio / Automation Runtime. It is not a "PC interface" and
therefore not shown in BIOS.
The RTS line must be switched by the driver for each transmission or reception; there is no automatic switch-
back mechanism.
The voltage drop resulting from long cable lengths can result in greater potential differences between the bus
stations, which can hinder communication. This can be improved by running the ground wire with the others.
2.3.5.2.3.3 RS485 - Bus length and cable type
The maximum transfer rate of 115 kbit/s depends on the cable length as well as the type of cable being used.
Extension
1200 m
The material used for the cable should have all of the following properties or deviate from them as little as possible
to achieve an optimal transfer rate.
