Safety Precautions
■Definition of Precautionary Information
WARNING Not following a precaution given as
a “Warning” may result in fatal or
serious injury.
■Warnings
WARNING Do not attempt to take the Unit apart
and do not touch any internal parts
while power is being supplied. Doing
either of these may result in electric
shock.
Precautions
1. When unpacking the Units, check carefully for any
external scratches or other damage. Also, shake the Units
gently and check for any abnormal sound.
2. Always tighten the connector screws after connecting
communication cables.
3. Double-check all the wiring before turning on the power
supply.
4. Confirm that the system will respond safely before turning
the power supply on or off.
5. Do not attempt to disassemble, repair, or modify the Units
in any way.
6. Dispose of the Units, according to local ordinances as
they apply.
Operating Precautions
You must allow sufficient leeway in ratings and performance
and provide proper fail-safe and other safety measures
when using the Unit in any of the following applications. Be
sure also to consult your PNSPO representative before
actually attempting any of these applications.
1. Applications under conditions or environments not
specified in user manuals.
2. Applications for nuclear reactor control, train facilities,
aviation facilities, motorised vehicles, furnaces, medical
equipment, amusement equipment and safety
equipment.
3. Applications strongly related to human life or property,
particularly those requiring safety.

Correct Use
1. Do not install the Unit in any of the following locations.
•Locations subject to rapid changes in temperature.
•Locations subject to temperatures or humidities outside
the range specified in the specifications.
•Locations subject to condensation as the result of high
humidity.
•Locations object to splashing chemicals or solvents.
•Locations subject to corrosive or flammable gasses.
•Locations subject to strong shock or vibration.
•Locations outdoors subject to direct wind and rain.
•Locations subject to strong ultra-violet light.
2. Take appropriate and sufficient countermeasures when
installing systems in the following locations.
•Locations subject to static electricity or other forms of
noise.
•Locations subject to strong electromagnetic or
magnetic fields.
•Locations close to power supply lines.
•Locations subject to possible exposure to radioactivity.
3. Do not use benzene, paint thinner or other volatile solvents,
and do not use chemically treated cloths.

1. Parts and Functions
The GWY-MPI and GWY-HMI are protocol converters that allow
PNSPO HMI terminals to be connected to other brands of PLC.
The GWY-MPI is specially designed for usage with Siemens S7-
300 and S7-400 PLC’s. This unit converts the PNSPO 3964R
protocol into Siemens MPI protocol.
The GWY-HMI allows you to connect PNSPO HMI to other
brands of PLC (Allen Bradley, Siemens, Schneider, etc.)
The following diagram shows the outline of the GWY-MPI and
GWY-HMI and explains the location and functions of the
different parts.
2. How to use the GWY-MPI
The GWY-MPI protocol converter is based on the Profibus chip.
When connected, the unit will be powered by the PNSPO!NS
terminal. The unit will convert the 3964R protocol into MPI
protocol and vice versa. The unit is developed in such a way
that it is a plug and play unit. There is no need for any
programming of the protocol converter.
NT-Link baudrate will be auto-detected, MPI baudrate is set to
187500 Baud. The GWY-MPI can read maximum 128 words
and write maximum 110 words.
3. How to use the GWY-HMI
The GWY-MPI protocol converter is based on the Profibus chip.
When connected, the unit will be powered by the PNSPO
terminal. The GWY-HMI needs to be programmed using the
GWY-SETUP SW. With this SW you can create a project
(mapping) which allows you to link addresses and coils of NON-
PNSPO products to PNSPO HMI terminals.
