Serial modules
provide communication with serial devices—such as chart recorders, barcode
readers, and security devices—or serial-based networks, such as Profibus
®
DP. Each module has
one or two serial ports.
•
Special-purpose modules
provide specific functionality, such as motion control or power
monitoring.
Inserting Modules
Up to 12 modules snap into place in the row of connectors inside the SNAP-IT unit. A maximum of
eight serial modules can be used in one SNAP-IT unit. All types of modules can be mixed in any
position on the rack.
EXCEPTION: SNAP-PAC-R1 controllers with serial numbers less than 600000 can use 4-channel digital
modules in module positions 0–7 only. All other module types can be in any position.
1.
Make sure all power to the SNAP-IT unit is off. Open the unit’s door and remove the small white
fuse from the module mounting rack.
WARNING:
Make sure there is no power to the rack before continuing, or you may severely damage
the module.
2.
Notice that each connector position on the mounting rack has a number, beginning with zero
on the far left.
3.
Position the module over the connector,
aligning the small slot at the base of the
module with the retention bar on the
rack.
4.
With the module correctly aligned over
the connector, push on the module to
snap it into position.
When positioning modules next to each
other, be sure to align the male and
female module keys (shown in the
detailed view in the illustration at right)
before snapping a module into position.
Modules snap securely into place and
require a special tool (provided) to
remove them. If you need to remove a
module, see
for instructions.
