Assembling Modules
The following example demonstrates the procedure for assembling the all-in-one 24-I/O type CPU module and an I/O
module together. When assembling slim type CPU modules, take the same procedure.
Disassembling Modules
1. When assembling an input or output module,
remove the expansion connector seal from the 24-I/
O type CPU module.
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 and
the blue unlatch button in the down position, press
the CPU module and I/O module together until the
latches click to attach the modules together firmly. If
the unlatch button is in the up position, push down
the button to engage the latches.
• Assemble Web server CPU modules together before mounting the modules onto a DIN rail. Attempt to
assemble modules on a DIN rail may cause damage to the modules.
• Turn off the power to the Web server CPU module before assembling the modules. Failure to turn power
off may cause electrical shocks.
Caution
Unlatch Button
1. If the modules are mounted on a DIN rail, first
remove the modules from the DIN rail as described in
“Removing from DIN Rail” on page 3-6.
2. Push up the blue unlatch button to disengage the
latches, and pull the modules apart as shown. When
disassembling slim type CPU modules, take the same
procedure.
• Remove the Web server CPU modules from the DIN rail before disassembling the modules. Attempt to
disassemble modules on a DIN rail may cause damage to the modules.
• Turn off the power to the Web server CPU module before disassembling the modules. Failure to turn
power off may cause electrical shocks.
