Assembling Modules
The following example demonstrates the procedure for assembling a CPU module and an I/O module together.
1. When assembling an analog input or output module, set the
rotary switch to select the desired operation mode. Use a small
flat screwdriver to turn the rotary switch.
2. Place the CPU module and I/O module side by side. Put the
expansion connectors together for easy alignment.
3. With the expansion connectors aligned correctly, press the
CPU module and I/O module together until the latches click to
attach the modules together firmly.
4. Press the end plate to each side of the module assembly. A pair
of end plates are supplied with each CPU module.
Caution
• Assemble OpenNet Controller modules together before mounting the modules onto a DIN rail.
Attempt to assemble modules on a DIN rail may cause damage to the modules.
• When using analog input or output modules, first set the rotary switch on the side of the module
to the desired input/output mode before assembling the module. The rotary switch cannot be
changed after the module has been assembled. For the operation modes of analog input and out-
put modules, see pages 2-28 and 2-31.
