lnlssol/docker-powerpmac repository overview

⁠Power PMAC module docker

This docker has the powerpmac module (https://github.com/dls-controls/pmac⁠) fixed to run on lnls.

⁠Building the image

Run

git clone https://gitlab.cnpem.br/SOL/Docker/powerpmac.git
cd powerpmac
docker build -t powerpmac_ioc .

⁠Running container

If you want to create a development folder on host computer, as you could do for your customized IOC, map the host folder on dev folder, which was created for this purpose:

docker run -it --rm -v /path/to/your/dev/folder/:/home/dev powerpmac_ioc bash

⁠Running Diamond IOC simple-power-pmac:

• Edit /usr/local/epics/apps/pmac/iocs/simple-power-pmac/iocBoot/ioclab/stlab.src , to use the right IP, changing this line:

drvAsynPowerPMACPortConfigure("BRICK1port", "172.23.247.1", "root", "deltatau", "0", "0", "0")

• Edit /usr/local/epics/apps/pmac/iocs/simple-power-pmac/labApp/Db/lab_expanded.substitutions to properly configure the motors.

  • The main fields are:
    • SREV: Number of controller counts (open loop) or encoder counts (closed loop) per turn of the motor
    • UREV: Number of units in EGU which the motor moves per turn. For closed loop, UREV = SREV×(Encoder Resolution)
    • MRES: UREV÷SREV
    • VMAX: Max motor speed in EGU
    • HLM: Software positive limit switch in EGU. 0 in this field means 'software limit switch disabled'
    • LLM: Software negative limit switch in EGU. 0 in this field means 'software limit switch disabled'

'
The example below setup a stepper motor in closed loop which has:
 SREV = 400 encoder counts per motor revolution
 UREV = 400×(Encoder Resolution) = 400*50 [nm] = 0.02 [mm]
 MRES = UREV÷SREV = 0.00005
 VMAX = 0.1 [mm/s]
 HLM = 0
 LLM = 0

    }

• After changing the substitutions, recompile the IOC:
  cd /usr/local/epics/apps/pmac/iocs/simple-power-pmac/
make clean uninstall install

• Then execute:

cd /usr/local/epics/apps/pmac/iocs/simple-power-pmac/iocBoot/ioclab/
/.stlab.sh

⁠Create your own IOC from scratch

If you want to build your customized IOC from scratch, follow the presentation⁠, which uses the slit⁠ setup for example.

⁠LNLS slit coordinated motion IOC

We have developed a simple coordinated motion using the simplest mecanism on our Lab: the slit. Check out our repository⁠!

⁠PowerPMAC trajectory generation

We are integrating the codes from Diamond Light Source⁠ on our setup. Check out our repository⁠!
