LOGO! CSM12/24
Delay resulting from latency When a frame passed through the CSM12/24, the stored and
forward function of the switch delays the frame according to the
characteristics below:
• With a 64 byte frame length by approx. 8 μs (at 100 Mbps).
• With a 1518 byte frame length by approx. 125 μs (at 100
Mbps).
Topology Star and bus topology
Note that the direct connection of two ports on the switch or
accidental connection over several switches causes an illegal loop.
Such a loop can lead to network overload and network failures.
Insulation of the ports You need shield all ports with each other that adhere to 1.5 kV
insulation voltage.

Tightening torque 0.57 Nm (5 lb in)
Use 75 °C conductors only. Use copper conductors only.
Functional grounding You can achieve functional grounding by connecting a cable from
terminal 3, for example to the DIN rail.
Keep this cable as short as possible.
Grounding is, however, not necessary for interference-free
operation.
