Development of Embedded EPICS on F3RP61-2L Jun-ichi Odagiri Presented by Tadahiko Katoh

Embedded EPICS on F3RP61-2L Abstract F3RP61-2L running Linux A module of FA-M3 PLC Can work as an IOC Off-the-shell EPICS runs on it Can work with/without PLC CPU As reliable as PLC CPU Boosts application development Oct. 17, 2008 @ EPICS'08 Embedded EPICS on F3RP61-2L

Embedded EPICS on F3RP61-2L Motivation Implementation and maintenance of ladder programs costs us a lot Having controller (PLC) under yet another controller (IOC) doubles the cost for application development Few ladder programmers (at J-PARC site) Emacs is better than any commercial ladder development tools Oct. 17, 2008 @ EPICS'08 Embedded EPICS on F3RP61-2L

Embedded EPICS on F3RP61-2L Make an intelligent interface board an IOC VxWorks, RTEMS, Linux, … Make a Digital Storage Oscilloscope running Windows an IOC Make the most front-end controller an IOC CC/NET(CAMAC Crate Controller) and Others Oct. 17, 2008 @ EPICS'08 Embedded EPICS on F3RP61-2L

Embedded EPICS on F3RP61-2L New Hope F3RP61-2L(for Yokogawa FA-M3 series PLC) Standard Linux Kernel (2.6.24.3-based) Preemption enabled Target dependent code is available under GPL I/O drivers is available under GPL BSP includes ELDK-based build tool chains All I/O modules of FA-M3 PLC are available EPICS device/driver support is just a wrapper of the kernel level I/O drivers Oct. 17, 2008 @ EPICS'08 Embedded EPICS on F3RP61-2L

Embedded EPICS on F3RP61-2L F3RP61 running EPICS on Linux Oct. 17, 2008 @ EPICS'08 Embedded EPICS on F3RP61-2L

Specifications of F3RP61-2L CPU: MPC8347E, 533MHz OS: Linux (kernel 2.6.24.3) DDR2 SDRAM: 128MB SRAM: 512KB (for system) User SRAM: 4MB I/F Ethernet: 100BASE-TX (2ch) RS-232C IEEE1394 CF Memory JTAG PCI RAS support Oct. 17, 2008 @ EPICS'08 Embedded EPICS on F3RP61-2L

Embedded EPICS on F3RP61-2L No modification of source code required Just add a new target to the configuration files IOC core program and EPICS sequencer run stably Implementation of EPICS device/driver support is a piece of cake Feature of each I/O module is expressed not in device/driver support but in the EPICS runtime database Oct. 17, 2008 @ EPICS'08 Embedded EPICS on F3RP61-2L

Real-time Responsiveness Soft real-time based on kernel 2.6 feature Preemptive option Time critical application can rely on PLC CPU Hard real-time extension may be available by using RTAI (under users responsibility) Oct. 17, 2008 @ EPICS'08 Embedded EPICS on F3RP61-2L

Embedded EPICS on F3RP61-2L Summary F3RP61-2L can be used as an IOC with ease Boosts application development for the front-end controller Gives us a cost-effective solution Hardware is as reliable as PLC CPU Soft real-time on kernel 2.6 feature Oct. 17, 2008 @ EPICS'08 Embedded EPICS on F3RP61-2L
