Communication with PLC devices by the TECO company (Czechia)

The EPSNET protocol

The standard solution is to communicate with TECO PLC devices (TECOMAT, TECOREG, ...) by the EPSNET monomaster protocol (the protocol comes from the definition of the transportation level of the PROFIBUS protocol).
 
For this communication in the PROMOTIC system can be used:
- PmTeco - Driver for communication with PLC devices by the TECO company
This driver can communicate via the computer's serial port or via Ethernet.
For easy integration of this driver into the application it is handy to use:
- Preconfigurations in group "TECO"


Type series Communications
TECOMAT TC400 2x serial port
TECOMAT TC500 2x serial port
TECOMAT TC600 3x serial port
TECOMAT TC650 3x serial port, 1x Ethernet
TECOMAT Foxtrot 2x serial port, 1x Ethernet
TECOMAT TC700 up to 10x serial port, 2x Ethernet
TECOREG TR050 2x serial port
TECOREG TR200 2x serial port
TECOREG TR300 up to 3x serial port

The OPC protocol

The TECO company supplies the OPC servers (OPC UA and OPC DA type) for communication with its devices.

- OPC UA:
For this communication in the PROMOTIC system can be used:
- PmOpcUaClient - Driver for communication with OPC UA server

- OPC DA:
This type of the communication is considered obsolete and it is better to use OPC UA.
For this communication in the PROMOTIC system can be used:
- The PmaOpcDaClientGroup object

The usage OPC (the PmOpcUaClient communication driver or PmaOpcDaClient object) requires purchase of the "PmOPC" licence. When developing the application in the freeware mode PmFree, or with development environment and while testing it in runtime, this component is always functional.
