Characteristics
The IF 964-DP interface submodule is used for connecting distributed I/O via
“PROFIBUS DP”. The submodule has an isolated RS485 interface. The maximum
transmission rate is 12 Mbps.
The permissible cable length depends on the transmission rate and the number of
nodes. In the case of a point-to-point connection with a speed of 12 Mbps, a cable
length of 100 m is possible, and with a speed of 9.6 Kbps a cable length of 1,200 m
is possible.
The system can be expanded to 125 stations.
