Module Preparation, Wiring and Installation
The modes of operation must be set internally to suit the conditions under
which the module will be used. In addition, switch contacts and
decoupling diodes must be wired to the module.
The module is capable of operating in a variety of modes depending on
the kinds of switches connected to it, whether the module is placed in a
local or remote I/O rack, and/or whether latched data in module memory
will be reset automatically or by program logic after the transfer of data.
The mode selection switch is mounted near the lower rear corner of the
printed circuit board under the left side cover of the module. It is
accessible by removing the four slotted cover screws on the right side of
the module.
The modes are selected by setting the mode selection switches ON or OFF
according to the positions defined in Figure 2.1.
