for model-specific information related to XL7/XL7
PRIME OCS models such as pin-outs, jumper settings, and other key installation information. Visit the
Horner websites to obtain datasheets, user documentation, and updates.
8.1
Overview
The XL7/XL7 PRIME OCS is a compact unit that contains high density, very versatile I/O. Using the I/O
properly requires wiring to the proper terminals, configuring jumpers inside the XL7/XL7 PRIME OCS unit
and configuring Cscape properly. This section will offer some tips and suggestions to configure the I/O
properly. For the register mapping of the I/O, refer to the
at the end of this manual for the pages
referencing register mapping.
8.2
Removing the XL7/XL7 PRIME OCS I/O Cover
Some I/O configurations require jumper settings to be changed in the XL7/XL7 PRIME OCS unit.
Examples of these settings are setting positive or negative logic on digital inputs or setting current or
voltage on analog inputs.
Each XL7/XL7 PRIME OCS I/O jumper is set to a factory default. Refer to the XL7/XL7 PRIME datasheet to
find the default setting to determine if a jumper change is necessary for a particular application.
To remove the I/O cover of the XL7/XL7 PRIME OCS, remove the four (4) Phillips screws from the I/O
back. It may help to place the XL7/XL7 PRIME OCS unit face down on a clean work surface. Once the four
screws are removed the I/O cover can be lifted straight off.
