Hi Kay：

Thank you for your response and important information.

We hope that we will update the control software from EPICS V3.13 to EPICS V3.14 in short time, especially keeping the existing the architecture of ControlLogix hardware. 

we perfer finding or converting driver of ControlNet interface module from V3.13 to V3.14, if there is no critical failure about ControlNet interface module. 

Of course, the Ethernet-based EPICS interface for A/B ControlLogix PLC will be second alternative.

Best regards,

Gang

> Hi all,We built the BEPC cryogenic and vacuum control system, using ControlLogix PLC via Controlnet module (EPICS driver originally developed by SNS of USA), based on EPICS Base R3.13(VME_IOC), about ten years ago,  at IHEP of China.

> Now, we want to update the control software from Base R3.13 to Base R3.14 with keeping the existing hardware. However, I could't find any information about EPICS Base R3.14 VxWorks driver of VME ControlNet interface module(5136-CN-VME)  from the website https://epics.anl.gov/modules/bus.php#VME%2dControlNet or https://ics-web.sns.ornl.gov/. 
> Has anyone converted VME ControlNet driver from R3.13 to R3.14? or knows the status of VME ControlNet driver support? Any advice or suggest is appreciated. Best regardsGang
