Page 15: Intended Audience
!WARNING It is extremely important that a PLC and all PLC Units be used for the speci- fied purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC system to the above mentioned applica- tions.
Page 16: Operating Environment Precautions
• The PLC outputs may remain ON or OFF due to deposits on or burning of the output relays, or destruction of the output transistors. As a counter- measure for such problems, external safety measures must be provided to ensure safety in the system.
Page 17: Application Precautions
• Locations subject to possible exposure to radioactivity. • Locations close to power supplies. !Caution The operating environment of the PLC System can have a large effect on the longevity and reliability of the system. Improper operating environments can lead to malfunction, failure, and other unforeseeable problems with the PLC System.
Page 18 • Be sure to press terminals until they are fully seated. • Mount Units only after checking terminal blocks completely. • Before mounting a wired terminal block to the main block, be sure that the terminal block-main block combination is correct.

This section describes the features of GRT1-series Slice I/O Units and lists the available Units. Slice I/O Terminal Introduction ........
Page 23: Slice I/O Terminal Introduction
The GRT1-series Slice I/O Units have the following features. Features Shared by all Units Small I/O Increments The GRT1-series Slice I/O Units have just a few I/O points (2 to 4 points) per Unit, so the application can be flexibly constructed to match the space and capacity requirements.
Page 24 This function records the total time that the Slice I/O Unit's internal circuit (Power ON Time) Monitor power has been ON. A warning level can be set in the Unit and a warning flag will be turned ON when the set warning time is exceeded. The Power ON Time can be read with an explicit message command or from the Configura- tor.
Page 25 Configurator or explicit messages. A warning set value can be set in the Unit to monitor the total ON time, and turn ON a warning flag in the Sta- tus Area when the set value is reached.
Page 26 Slice I/O Terminal Introduction The status can be checked at the Master using the Off-wire Detection Flag. This function is valid only for the input ranges 4 to 20 mA and 1 to 5 V. User Adjustment Input or output values can be adjusted to compensate for errors in the input or output voltage or current resulting from the characteristics or connection methods of the I/O device.
Page 27 The temperature differences between input channels 0 and 1 can be calcu- Channels lated and compared to a set value. The host will be notified with a flag when the temperature difference exceeds a set value.
