abstract = {{In order to make the system stable and reliable, Programmable Logic Controllers (PLCs) are widely used to realize the slow control and interlock control of the accelerator control system. EPICS is a set of software tools used to build control systems for large scientific instruments such as particle accelerators. A prototype of communication between Inovance PLC and EPICS IOC was built by using a Inovance AC812 PLC controller. In order to simplify the system structure and reduce the development cost, the EPICS IOC was run in the AC812 PLC controller while running standard PLC program. The PLC program running in the AC812 PLC controller communicates with the EPICS IOC through the Modbus protocol, so as to integrate the data from the AC812 PLC controller into the EPICS IOC. Based on the brief introduction of EPICS, AC812 PLC controller and EPICS Modbus driver, the communication between the AC812 PLC controller and the EPICS IOC using EPICS Modbus drivers was tested. The test results show that the communication between the AC812 PLC controller and the EPICS IOC using the EPICS Modbus driver is smooth.}},
