Here's a question from Juliane Reinhardt, ALS:

  > anyone having some advice for connecting motors to a smarAct MCS
controller? What does the channel number mean? Our .iocsh file looks
like this

### Motors
# Motors substitutions, customize this for your motor
dbLoadTemplate "motor.substitutions.smaractmcs_201"# Configure each
controller
#origvalues# drvAsynIPPortConfigure("MCS_ETH","192.168.1.17:2102",0,0,0)
drvAsynIPPortConfigure("MCS_ETH","192.168.168.201:5000",0,0,0)#
Controller port, asyn port, number of axis, moving poll period, idle
poll period
# smarActMCSCreateController(const char *motorPortName, const char
*ioPortName, int numAxes, double movingPollPeriod, double idlePollPeriod);
smarActMCSCreateController("MCS", "MCS_ETH", 1, 0.020, 1.0)# Controller
port, axis number, controller channel
# smarActMCSCreateAxis(const char *motorPortName, int axisNumber, int
channel)
smarActMCSCreateAxis("MCS", 0, 0);

This doesn't seem to be a good thing.
The axis number is the EPICS axis number - it must start with 1.

The channel is the axis number inside the controller - I don't
know if they start counting at 0 ?

Not having such a controller, I would speculate and try
smarActMCSCreateAxis("MCS", 1, 0);
