About the Device/PLC Connection Manuals
Prior to reading these manuals and setting up your device, be sure to read the
"Important: Prior to reading the Device/PLC Connection manual" information. Also,
be sure to download the "Preface for Trademark Rights, List of Units Supported, How
to Read Manuals and Documentation Conventions" PDF file. Furthermore, be sure
to keep all manual-related data in a safe, easy-to-find location.

Device Net - Slave I/O
GP-PRO/PBIII for Windows Device/PLC Connection Manual
• Only the LS Area's User Area (from LS20 to LS1999) is used for this
communication.
• The System Area (from LS0 to LS19) and Reading Area settings cannot be
used for PLC communication.
• GP will be used as a slave unit.
• Explicit Message Communication is not supported.
• The Contents in System Area are programless.
Note:
Slave I/O
Slave I/O is the feature that converts I/O data automatically between the PLC installed with the master unit and GP unit.
Slave I/O uses a special link method that does not allow a user to access a PLC
directly .
When using Device Net Connection the GP series unit performs like an I/O terminal
(Remote terminal). The GP's LS area will be used as a device which inputs/outputs
data with the host (PLC).
The master (host PLC) unit Output area is allocated to GP's Input area, and the
master's Input area is allocated to GP's Output area. The LS area's Input area is
followed in sequence by the Output area. (See below)

After all connector wires are attached to the connector, connect the connector to the
Device Net I/F Unit (5-wire type).
Be sure to connect T erminating Resistors (121Ω1/4W) to both sides of the cable.

List Device Net Cables
There are two types of cable, thick and thin, for the Device Net unit.
Be sure to use only cables that meet the Device Net specifications. The following
two cables are recommended.
• Rockwell (Allen Bradley) Thick type 1485C-PI-A***
• Rockwell (Allen Bradley) Thin type 1485C-PI-C***

For setting the baud rate and the node number, use the Dip Switch (8 positions) on
the rear side of the Device Net expansion unit (Model: GP070-DN41). The normal
SIO communication setting cannot be used. Node number is available from0 to 63
on the GP .
