I/O Block
WBPEEUI240751C0 7 - 5
When the I/O block has both digital input and output capabili-
ties, the channel indicators are segregated into input (I) and
output (O) groups on the front panel.
ID Labels
The front panel contains two labels at the bottom of the I/O
module: inner label and outer label. The labels are located in a
small recess covered by a removable clear plastic lens.
Inner Label
Permanently adhered to the block. It gives device identification
information which includes the device ID number and a device
description. The device ID is both a serial number and the
unique electronic ID assigned at the factory. The following is
an example inner label:
Outer Label
For customer use. Provides an area for customer identification
of the particular block. It also contains a brief I/O block appli-
cation description. The following is an example outer label:
I/O Module Rear Panel
Figure 7-2 shows the typical rear panel of an I/O module. The
switches, jumpers, and connectors are recessed to allow rest-
ing the assembly face up on a table.
For a CIO-100 block, P4 is a station link connector rather than
redundancy link and is labeled as such. For DIO blocks, the
field power select jumpers are for digital output field power
and are labeled as such.
Table 7-4 summarizes the SW2 special operations switch
settings.
