Preface
■ About this Guide
GL20‑RTU‑PN series PROFINET communication interface module features support for
PROFINET communication and is applicable to PROFINET master devices such as S7‑
1500 and S7‑1200. One PROFINET module can connect up to 16 GL20 I/O modules.
When the number of connected I/O modules exceeds 16, an expansion power supply
module is required (one power supply module for every 16 additional I/O modules).
This guide describes the mechanical installation, electrical installation and
programming examples of the product.

Safety Instructions
■ Safety Precautions
1. Before installing, using, and maintaining this equipment, read the safety
information and precautions thoroughly, and comply with them during operations.
2. To ensure the safety of humans and equipment, follow the signs on the equipment
and all the safety instructions in this user guide.
3. "CAUTION", "WARNING", and "DANGER" items in the user guide only indicate some
of the precautions that need to be followed; they just supplement the safety
precautions.
4. Use this equipment according to the designated environment requirements.
Damage caused by improper use is not covered by warranty.
5. Inovance shall take no responsibility for any personal injuries or property damage
caused by improper use.
■ Safety Levels and Definitions
: Indicates that failure to comply with the notice will result in death or
severe personal injuries.
: Indicates that failure to comply with the notice may result in death or
severe personal injuries.
: Indicates that failure to comply with the notice may result in minor or
moderate personal injuries or damage to the equipment. Please keep this guide well
so that it can be read when necessary and forward this guide to the end user.
During Control System Design
●Provide a safety circuit outside the PLC so that the control system can still work safely
once external power failure or PLC fault occurs.
●Add a fuse or circuit breaker because the module may smoke or catch fire due to long‑
time overcurrent caused by operation above rated current or load short‑circuit.

‑5‑
●An emergency stop circuit, a protection circuit, a forward/reverse operation interlocked
circuit, and a upper position limit and lower position limit interlocked circuit must be set
in the external circuits of PLC to prevent damage to the machine.
●To ensure safe operation, for the output signals that may cause critical accidents, please
design external protection circuit and safety mechanism;
●Once PLC CPU detects abnormality in the system , all outputs may be closed; however,
when a fault occurs in the controller circuit, the output may not be under control.
Therefore, it is necessary to design an appropriate external control circuit to ensure
normal operation.
●If the PLC output units such as relays or transistors are damaged, the output may fail to
switch between ON and OFF states according to the commands.
●The PLC is designed to be used in indoor electrical environment (overvoltage category II).
The power supply must have a system‑level lightning protection device, assuring that
overvoltage due to lightning shock cannot be applied to the PLC power supply input
terminals, signal input terminals and output terminals and so forth, so as to avoid
damage to the equipment.
Installation
●Installation must be carried out by the specialists who have received the necessary
electrical training and understood enough electrical knowledge.
●Disconnect all external power supplies of the system before removing/installing the
module. Failure to do so may result in electric shock, module fault or malfunction.
●Do not use the PLC where there are dust, oil smoke, conductive dust, corrosive or
combustible gases, or exposed to high temperature, condensation, wind & rain, or
subject to vibration and impact. Electric shock, fire and malfunction may also result in
damage or deterioration to the product.
●The PLC is open‑type equipment that must be installed in a control cabinet with lock
(cabinet housing protection > IP20). Only the personnel who have received the necessary
electrical training and understood enough electrical knowledge can open the cabinet.

‑6‑
●Prevent metal filings and wire ends from dropping into ventilation holes of the PLC
during installation. Failure to comply may result in fire, fault and malfunction.
●Ensure there are no foreign matters on ventilation surface. Failure to comply may result
in poor ventilation, which may cause fire, fault and malfunction.
●Ensure the module is connected to the respective connector securely and hook the
module firmly. Improper installation may result in malfunction, fault or fall‑off.
Wiring
●Wiring must be carried out by personnel who have received the necessary electrical
training and understood enough electrical knowledge.
●Disconnect all external power supplies of the system before wiring. Failure to comply
may result in electric shock, module fault or malfunction.
●Install the terminal cover attached to the product before power‑on or operation after
wiring is completed. Failure to comply may result in electric shock.
●Perform good insulation on terminals so that insulation distance between cables will not
reduce after cables are connected to terminals. Failure to comply may result in electric
shock or damage to the equipment.
●To avoid electric shock, cut off the power supply before connecting the product to the
power supply.
●The input power of the product must meet the specifications listed in this guide. If the
power input does not meet the specifications, the equipment may be damaged. Thus,
check regularly that the DC power provided by the switching‑mode power supply unit is
stable.
During Operation and Maintenance

‑7‑
●Maintenance & inspection must be carried out by personnel who have the necessary
electrical training and experience.
●Do not touch the terminals while the power is on. Failure to comply may result in electric
shock or malfunction.
●Disconnect all external power supplies of the system before cleaning the module or re‑
tightening screws on the terminal block or screws of the connector. Failure to comply
may result in electric shock.
●Disconnect all external power supplies of the system before removing the module or
connecting/removing the communication wirings. Failure to comply may result in electric
shock or malfunction.
Safety Recommendations
●On‑site manual devices or other backup means must be equipped in the position where
the operator directly touches the mechanical parts, such as loading and unloading
mechanical tools, or the position where the machine runs automatically. The manual
devices and backup means, which can start or interrupt automatic operations of the
system, must be independent of the programmable controller.
●If you need to modify the program while the system is running, use the lock function or
other protective measures. Ensure that only authorized personnel can make the
necessary modifications.
Disposal
●Treat the scrapped product as industrial waste. Dispose of the battery according to local
laws and regulations.
●Recycle retired equipment by observing industry waste disposal standards to avoid
environmental pollution.
