The GRT1 series is a Smart Slice I/O system which allows up to 64 small input/output modules to be plugged into a single communications module.
This gives the slave configuration flexibility so it can match user requirements more accurately. It can also be added to at a later date.
The SmartSlice I/O units are usually piggybacked into one another, but up to two turn-back units can be added if installed in a confined space. The range has recently been expanded with a number of additional modules, including two-channel analog inputs and outputs, high-speed counter and positioning modules. Currently, only a DeviceNet slave communication interface is available although connections to other fieldbuses can be anticipated in the future.
The entire range uses screw-less I/O terminals for quicker and easier wiring. Smaller terminals mean greater I/O density for the given space. The I/O modules can be added or removed while the system is powered and the communication module itself retains I/O unit configuration settings for easier replacement during maintenance.
The GRT1 is part of Omron's 'Smart' series. This means that in addition to the normal I/O status, Smart slaves also report data for I/O and network power supply monitoring, error history, record last maintenance date, etc to their master. These features are suitable for sites where preventive maintenance is carried out. The smart series also offers auto baud rate detection, alleviating the need for separate hardware setting.
