TES Industrial Module – Modbus RS-485 Remote I/O for Electrical Substations
The TES industrial modules from LEROY Automation are remote I/O terminals, Modbus slaves over RS-485 network, specially designed for site monitoring, technical management, and industrial data acquisition. Ideal for electrical substations, these modules ensure quick integration with the TESIS configuration tool. With pre-programmed smart functions and a predefined Modbus communication mapping, the TES modules provide simplified implementation and optimal reliability.
The TES range includes specialized variants such as the TES Mirror, TES Chronology, and TES Front, tailored to specific automation needs. Although this series is no longer manufactured, LEROY Automation continues to offer maintenance and repair services to extend the lifespan of your Modbus module for electrical substations and ensure the continuity of your industrial installations.
The “TES” modules are at the end of their lifecycle and are no longer manufacturable. However, we can offer you solutions to ensure the sustainability of your installations through after-sales services (diagnostics and repairs), operational maintenance (OM), and upgrades/migration to the most suitable control-command platforms for your industrial applications.
TES with digital inputs/outputs
TES with analog inputs/outputs
Inputs : 10 bits resolution, 0-10V ou 0-20mA
Outputs : 15 bits resolution, 0-10V ou 0-20mA
Analog TES also systematically have 4 digital inputs and 4 digital outputs.
TESIS32 allows the TES’s commissioning in few minutes :
A TES Mirror is a TES Modbus master associated in pairs with a conventional TES Modbus slave remote (described above) .
It has mirror inputs / outputs of the conventional TES.
It transmits the state of its inputs to the outputs of the remote TES and conversely reads the inputs of the remote TES to copy them on its outputs.
The distance between the two can reach 3km.
At power-on, the master TES tries to communicate perpetually with a remote TES slave no. There is no setting. The communication is established automatically according to the communication parameters of the remote TES.
The TES “CHRONOLOGY” is a TES with 32 logical inputs (based on the hardware of a TES32ET) that detects the state changes of its inputs with a resolution of 2ms.
It timestamps these changes and puts them in a queue event waiting to be accessed by the Modbus master of the network.
The resynchronization of the clock, to compensate for the drifts, is carried out either by a TOP rising edge on an input (model Chrono2000) or by a synchronization frame broadcast in broadcast on the network (model Chrono32ET) .
It is perfectly adapted to the traceability of the trips in the electrical cabinets.
The centralizer TES is a Modbus master on the RS485.
It assures the cyclical exchanges with the multiple slaves of a network and builds a Modbus table with the data collected to the higher system.
Conversely, it can receive commands via RS232 from a master, and transfer them to the slaves on the RS485.
The TES can ensure the transfer of data between slaves without using a higher system.
The HERMES software tool allows to declare the frames to be launched cyclically or on demand, to define the exchange table with the system above.
