Wiring the ET 200L TB 16L/TB 32L Terminal Block
When wiring the ET 200L distributed I/O device, we distinguish between the
terminal block with its supplementary terminal and the electronics block.
S
The terminal block and, if required, the supplementary terminal carry the
wiring.
S
The electronics block incorporates the PROFIBUS-DP connection.
All terminal connections on the terminal block and supplementary terminals
are located on the front and are clearly marked and readily visible from the
front. Assignment of terminal connections to input/output channels is simple
to perform, without danger of confusion.
Connect the terminal block and the supplementary terminal in accordance
with the configuration. Figure 3-3 shows the terminal connections for termi-
nal block TB 16L. Its pinout is described in Chapter 7.
