CODESYS, the Optimal Solution for the IoT Era.
The PAC Series supports CODESYS programming, which complies with the IEC 61131-3 international standard, and is equipped with functions to enable the manufacturing industry to construct open systems. Enables the overall optimization of systems by integrating PLC and HMI control and implementing open communication.
Integrated Development Environment
An integrated development environment for developing applications can be downloaded free of charge.This makes it possible to seamlessly perform development such as control logic and field bus I/O.
- Supported Integrated Development Environment:
- V3.5 SP7 Patch 2 or later.
- Supported Languages:
- LD / SFC / FBD / ST / IL / CFC
- IEC 61131-3 compliant Up to 6 programming languages are supported.
- Up to 11 types of fieldbus protocols are available.*
- Supports OPC UA that is adopted by Industrie 4.0 standard.
CODESYS Integrated Development Environment
A CODESYS development environment, that has been integrated PLC programming, fieldbus settings, etc. is provided free of charge. It overwhelmingly reduces the man-hour of developing an automation system in the production site.

PLC Programming
Supports all 5 types of IEC61131-3 standard programming languages (ST, LD, FBD, SFC, IL), and CFC programming languages.
Also supports objectoriented programming defined in IEC 61131-3 third edition.
- ST (Structured Text)
- LD (Ladder Diagram)
- FBD (Function Block Diagram)
- SFC ( Function Chart)
- IL (Instruction List)
- CFC (Continuous Function Chart)
“Connecting” Controller
Because CODESYS supports OPC UA, a standard communication protocol, and various types of fieldbus protocols, it contributes to the rapid popularization of Industrial IoT. Communication settings of OPC UA and the field buses are all possible from the CODESYS integrated development environment. This enables seamless development of many things ranging from control programs to fieldbus communication settings and assignment of slave I/O variables, thus greatly reducing engineering work-hours.
Inter-device Communication
- OPC UA
- OPC Classic
- Serial Communication
- TCP/UDP Communication, etc.
Supported Field Buses*
- EtherCAT
- EtherNet/IP
- PROFIBUS
- J1939
- I/O-Link
- IEC 61850
- PROFINET
- Sercos
- CANopen
- Modbus TCP/RTU
- BACnet
Open Scalability: CODESYS STORE
A variety of packages ranging from sample programs to plug-ins for communication with SQL are available in the "CODESYS STORE." Some of the packages in this online store are free and some are not. In addition to the packages provided by CODESYS as standard, a wide variety of third-party tools have also been released, which provides the system with scalability.
PAC Controller Functionality

Web monitoring Function Using Built-in CONPROSYS HMI
CONPROSYS PAC series includes a web server function and web screen creation software. Monitoring screens can be developed in a user friendly web browser environment. Devices can be monitored through a web browser without the use of a cloud server. No programming experience required.
Fieldbus Master Function
The built-in customized CODESYS Runtime engine supports EtherCAT / Modbus TCP master functions. In the CODESYS integrated development environment, fieldbus I/O can be directly assigned to variables in the same manner as the built-in I/O of a PAC integrated controller and the attached I/O of a PAC configurable controller.
Built-in OPC UA server for SCADA/MES/EPR linking
The built-in OPC UA server provides the ability to embed the CONPROSYS. PAC series controller into a host SCADA system or other applications that support OPC UA protocol.
Integrated Type
The integrated type offers a wide range of models with a variety of I/O interfaces
and communication protocols.

EtherCAT Slave Controller
- CPS-ECS341-1-011
- The EtherCAT slave unit is used to monitor or control equipment in Ethernet-based EtherCAT networks. An EtherCAT network connects an EtherCAT master controller to slave unit(s) by LAN cable(s) (RJ-45). Users can attach CONPROSYS I/O modules to EtherCAT slave units to suit a variety of applications including semiconductor and FPD manufacturing equipment, machine tools, test benches, and transportation systems.
- EtherCAT Slave Unit
- EtherCAT features allow the I/O modules to be controlled from a distance. Up to 16 I/O modules can be stacked to one slave unit.
- Work with CONPROSYS PAC Series Controllers
- Together with the PAC series EtherCAT master controller, an all Contec devices EtherCAT system is available.
- Modular Device Profile (MDP)
- The EtherCAT slave unit complies with the EtherCAT Modular Device Profile (MDP) standard (ETG.5001.1). An MDP standard supported master will recognize and register the I/O modules automatically.
- Daisy Chain Connection
- Each slave unit is equipped with an input port and an output port. Up to 65,535 slave units can be connected to one master.
