Hi John,

Ø Is the TC32 supported by PROD_IOC_LINUX measCompApp ?

Yes, but as the R2-0 release notes say, it has not been tested on Linux yet (because I don’t own one).

Ø The TC32 is connected via ethernet and configured to be Board# 1

I assume you mean it was configured as Board #1 with InstaCal? On Linux the InstaCal assignment of board numbers is not used. Rather you need to add a cbAddBoard() command to your startup script before the call to MultiFunctionConfig().

Here is the difference between st.cmd and st.cmd.linux in iocBoot/iocETC for the E-TC thermocouple module.

corvette:measComp/iocBoot/iocETC>diff st.cmd st.cmd.linux

9a10,11

> cbAddBoard("E-TC", "164.54.160.218")

You should add this line to your st.cmd file where xxx.xxx.xxx.xxx is the IP address of the device.

cbAddBoard("E-TC32", "xxx.xxx.xxx.xxx")

The first cbAddBoard command will define board #0, the second will define board #1, etc. So you will use board=0 in MultiFunctionConfig().

Let me know if this works for you.

Mark

Subject: measComp 2-1 and TC32

I am confused about the status of support for Measurement Computing TC32 on linux.

measComp-R2-1/measCompApp/src

the Makefile includes the lines:

PROD_IOC_WIN32 += testTC32

testTC32_SRCS += testTC32.c

ifeq (win32-x86, $(findstring win32-x86, $(T_A)))

testTC32_LIBS += cbw32

else ifeq (windows-x64, $(findstring windows-x64, $(T_A)))

testTC32_LIBS += cbw64

endif

but there is not a testTC32 IOC for linux. Is the TC32 supported by PROD_IOC_LINUX measCompApp ?

I tried running measCompApp with a single thermocouple.

The TC32 is connected via ethernet and configured to be Board# 1

Here is the IOC console on start-up:

jad22@erp201 $ ../../bin/linux-x86_64/measCompApp st.cmd

InstaCall reports a reasonable temperature.

I am completely new to this device and to Measurement Computing support.

Any help appreciated.
