# masterMacs
|
|
|
|
## <span style="color:red">Please read the documentation of sinqMotor first: https://git.psi.ch/sinq-epics-modules/sinqmotor</span>
|
|
|
|
## Overview
|
|
|
|
This is a driver for the masterMacs motion controller with the SINQ communication protocol. It is based on the sinqMotor shared library (https://git.psi.ch/sinq-epics-modules/sinqmotor). The header files contain detailed documentation for all public functions. The headers themselves are exported when building the library to allow other drivers to depend on this one.
|
|
|
|
Compatible to MasterMACS software 2.0.0.
|
|
|
|
## User guide
|
|
|
|
This driver is a standard sinqMotor-derived driver and does not need any specific configuration. For the general configuration, please see https://git.psi.ch/sinq-epics-modules/sinqmotor/-/blob/main/README.md.
|
|
|
|
The folder "utils" contains utility scripts for working with masterMacs motor controllers:
|
|
- decodeStatus.py: Take the return message of a R10 (read status) command and print it in human-readable form.
|
|
- decodeError.py: Take the return message of a R11 (read error) command and print it in human-readable form.
|
|
- writeRead.py: Send messages to the controller and receive answers.
|
|
|
|
## Developer guide

|
|
### Usage in IOC shell
|
|
|
|
masterMacs exposes the following IOC shell functions (all in masterMacsController.cpp):
|
|
- `masterMacsController`: Create a new controller object.
|
|
- `masterMacsAxis`: Create a new axis object.
|
|
|
|
The full mcu.cmd file looks like this:
|
|
|
|
```
|
|
# Define the name of the controller and the corresponding port
|
|
epicsEnvSet("NAME","mcu")
|
|
epicsEnvSet("ASYN_PORT","p$(NAME)")
|
|
|
|
# Create the TCP/IP socket used to talk with the controller. The socket can be adressed from within the IOC shell via the port name
|
|
drvAsynIPPortConfigure("$(ASYN_PORT)","172.28.101.24:1025")
|
|
|
|
# Create the controller object with the defined name and connect it to the socket via the port name.
|
|
# The other parameters are as follows:
|
|
# 8: Maximum number of axes
|
|
# 0.05: Busy poll period in seconds
|
|
# 1: Idle poll period in seconds
|
|
# 1: Socket communication timeout in seconds
|
|
masterMacsController("$(NAME)", "$(ASYN_PORT)", 8, 0.05, 1, 1);
|
|
|
|
# Define some axes for the specified MCU at the given slot (1, 2 and 5). No slot may be used twice!
|
|
masterMacsAxis("$(NAME)",1);
|
|
masterMacsAxis("$(NAME)",2);
|
|
masterMacsAxis("$(NAME)",5);
|
|
|
|
# Set the number of subsequent timeouts
|
|
setMaxSubsequentTimeouts("$(NAME)", 20);
|
|
|
|
# Configure the timeout frequency watchdog:
|
|
setThresholdComTimeout("$(NAME)", 100, 1);
|
|
|
|
# Parametrize the EPICS record database with the substitution file named after the MCU.
|
|
epicsEnvSet("SINQDBPATH","$(masterMacs_DB)/sinqMotor.db")
|
|
dbLoadTemplate("$(TOP)/$(NAME).substitutions", "INSTR=$(INSTR)$(NAME):,CONTROLLER=$(NAME)")
|
|
epicsEnvSet("SINQDBPATH","$(masterMacs_DB)/masterMacs.db")
|
|
dbLoadTemplate("$(TOP)/$(NAME).substitutions", "INSTR=$(INSTR)$(NAME):,CONTROLLER=$(NAME)")
|
|
dbLoadRecords("$(masterMacs_DB)/asynRecord.db","P=$(INSTR)$(NAME),PORT=$(ASYN_PORT)")
|
|
```
