CODESYS runtime supported protocols
The built-in CODESYS runtime for the cMT and cMT X series supports the following protocols for communicating with external party devices:
- Modbus TCP/IP (Master, AKA. Client), up to 32 devices
- EtherCAT (Master, AKA. Client), up to 65,535 devices
- EtherNet/IP (Master, AKA. Client), up to 32 devices
- CANopen (Master, AKA. Client), up to 126 devices
- PROFINET (Controller, AKA. Master), up to 64 devices
When structuring a project in CODESYS IDE for the cMT Series’ built-in CODESYS runtime, users are advised to utilize the following drivers:
| CODESYS IDE Device | Recommended Version |
|---|---|
| Ethernet adapter (added above any drivers for connecting to ethernet devices) | 3.5.15.0 |
| EtherNet/IP Scanner | 3.5.15.50 |
| Modbus TCP Master/Modbus TCP Client | 3.5.15.0 |
| EtherCAT Master/EtherCAT Client | 3.5.12.0 |
| CANbus | 3.5.15.0 |
| CANopen Manager | 3.5.15.0 |
| PN-Controller | 3.5.12.60 |
Note: The built-in CODESYS runtime is not natively able to act as a Modbus TCP Slave/Server using a single Modbus Slave/Modbus Server device in the Device Tree of a CODESYS IDE project. Users can, however, utilize function blocks provided by the ModbusTCP Slave library to achieve similar functionality.
Note: The built-in CODESYS runtime must be running on a cMT series device featuring a CANbus interface to offer CANopen functionality in CODESYS IDE projects.
